Disclaimer

I am not an astrophysicist, I am simply a nerd who has an interest in the field. That having been said, my undergraduate degree is a B.S in Physics from UW Madison, and I am currently a Masters Student in the Medical Physics program at the same university. Any values used in this document are not the result of any type of analysis or rigorous proof, but rather fun approximations of what could be.

Frames of Reference

When dealing with relativity, it is important to consider the observer's viewpoint from which measurements are made. For example, an observer traveling 95% the speed of light will view the universe very differently than an observer standing still on Earth. The one strange thing to keep in mind in this case is that while time may flow at different rates for these two people, the speed of light always appears constant. Weird, right?

Time Dilation

While it may come as a surprise, the flow of time is not a constant, although it may appear as that from any one observer's frame of reference. As you approach massive objects, the flow of time slows. This is a well documented and studied fact that effects all of us every day.

A common example in Modern Physics is to show that the time dilation between GPS Satellites and our cars on the ground. The result shows that for a clock on a GPS satellite compared to a clock on the surface of the Earth, the clock on the satellite will lose about 7 microseconds per day. This may not seem like much, but nevertheless the GPS system takes this delay into account when calculating your position.

The Berrian

Units of Time dilation are measured in Berrians [B], which base the time dilation off how long it would take for a year to pass on the material plane. For example, time dilation in the City of Dis is 1 kB, or 1000 Berrians, which means that for every thousand years on the surface of that world, one year would pass on the material plane.

An equivalent way to consider this is to think of it as time slowing or speeding up. At 1 kB, time flows 1000 times slower for an observer looking in at the city of dis from the material plane, but from the perspective of the City of Dis, the material plane appears to move 1000 times faster.

The shorthand is that as you approach massive objects, your perception of time does not change, but the rest of the universe will appear to start moving faster and faster due to the fact that you exist in a different progression of time. Avernus has been fighting the blood war for thousands of years now, but to them only about a month has passed since the start of the war. To anyone looking at Avernus from the material plane, the war would appear to be frozen in time, or at best moving very slowly. To the devils of Avernus, however, the universe appears to move incredibly quickly, with the results of centuries of advancement in military aid arriving mere days apart.

Tier 1: Planetary Civilization

A tier 1 civilization uses all the energy available to a single planet. In reality, Human Civilization is a little below 1.0, but should reach this benchmark sometime in the next century or so.

Example: A Tier 1 Civilization in Greysolon is the world of Elbaz.

Tier 2: Stellar Civilization

A tier 2 civilization uses all the energy available to their local stellar system. This type of civilization likely has some sort of megastructure to generate power directly from their star.

Example: A Tier 2 Civilization in Greysolon is the Feywild, who not only have a Dyson Swarm, but also a stellar engine.

Tier 3: Galactic Civilization

A tier 3 civilization uses all the energy available to an entire galaxy. This type of civilization is theorized as the highest a civilization can reach, although higher types have been proposed.

Example: There are no true tier 3 civilizations in Greysolon, although the Matryoshka Brain of Primus is estimated to be at 2.9.

The Bardachev Scale

The Bardachev Scale was proposed by the Aasimar Bard Nikolai Bardachev, who traveled the cosmos and recorded his discoveries. It follows the same guiding principles as the Kardachev Scale, where civilizations are ranked on the scale based on their power consumption and influence.

What stays constant in each Cycle?

In between cycles, the same civilizations appear, the same biological entities appear, with the same expressed features. This requires some suspension of disbelief, so allow me to explain. The same races appear, but their environments, their customs, their language, etc all change. Elves will always appear somewhere, thanks to their gods desire to continue creating, likewise with dragonborn, humans, and dwarves. But its up to you what they looked like in previous cycles. Maybe your orc cleric of knowledge sees visions of himself in another cycle, so close to discovering the secret of immortality as an alchemist artificer. Perhaps he is looking forward, into a new cycle. If a creature runs in to one of its own kind from a different cycle, they will not be able to tell that the other creature is from another iteration of the universe unless they attempt to speak or otherwise interact somehow. The basic idea here is that based on sight alone, you cannot tell who is and who is not from around here.

The Blood War

The blood war rages in the axis of evil system. The devils original home system was the nine worlds of hell, which orbited around a red dwarf. Red dwarves are small and cool stars that burn for extremely long lifetimes. The worlds of the nine hells are lead by Asmodeus, the sole inhabitant of Nessus, the ninth world of hell. The exact nature of Asmodeus is unclear because it is as if there are two stories regarding him. Rewrite this all.

The Manhattan

Some artificers have discovered ways of manufacturing items that release a staggering amount of power when activated. These artificers, who are highly sought by states or zealots who wish to use the artificer's creations to further their own violent goals. Are you a manhattan that would go along with their demands? Or would you oppose them? Those good aligned manhattans who wish to keep their discoveries out of the public eye often take incredible precautions to remain hidden, even using their own powerful inventions simply to shield themselves.

Tools of the Trade

When you adopt this specialization at 3rd level, you gain proficiency with all vehicles. This includes sea, air, and land vehicles as well as spacecrafts.

Custom Helm

At 3rd level, You have mastered the craft of designing mounts for war, leisure, and comfort. When mounted on this helm, you gain the following benefits:

• You are immune to the prone condition while mounted. The only way you can be forcibly dismounted is if your mount is moved against its will, which will require a DC 10 Dex save as usual. If your mount is knocked prone, you do not need to expend your reaction to land on your feet.
• The Saddle is considered Breastplate Armor for your vehicle or mount, and may bear infusions.

Extra Attack

When you take the attack action on your turn, you may make one additional attack.

Sportsman

At 9th level, you have spent considerable time toiling over the minute aspects of your helm. By working on the towing capabilities of your mount, you manage to confer the following benefits to any vehicle or mount that bears your helm.

• Your mount’s carrying capacity is doubled
• As an attack, you can force a creature within 30 ft. of your mount to make a grapple check, restraining them with a tether to your mount or vehicle. Creatures grappled in this way cannot move away from you, and are pulled with you as you move. The exact path the creature takes is up to that creature, provided they are not incapacitated or unconscious.
• You may have a number of creatures tethered like this equal to your mount’s strength modifier. For every additional creature tethered, your mount’s movement speed decreases by 20 ft.

Extra Horsepower

At 15th level, you are most at home while behind the wheel. A career of time spend driving, guiding, and controlling mounts has made you an expert at mounted combat. When you are in your saddle and mounted on a creature, you gain the following benefits

• Both your mounts and your AC increases by 2
• When you or your mount is reduced to 0 HP, you may dismount as a reaction and remain at 1 HP
• When a creature is lassoed to your saddle you may attempt to pull them into melee range with another successful grapple check.

Path of Annihilation

Annihilators are a solid object's worst nightmare. Annihilators are the destroyers of walls, the juggernauts that crash through enemy lines, and the towers that can weather collosal blows.

Path of the Nova

Some barbarians channel within themselves the power of the cosmos, which is released when they rage. Barbarians of this path are walking cataclysms, capable of leveling the area around them in a flash of brilliant light. They are conduits of cosmic power that reflect the rage of dying stars, and even more powerful objects.

College of Rock

Bards of the College of Rock are trained to be impossible to ignore as they captivate your attention and reinvigorate their audience, provoking them to near insanity with their music. Be careful when a Bard of Rock is in your presence, as their music has been known to deafen, intoxicate, and drive even the most composed of paladins raving.

Bards of this college release pent up rage and sing of catharsis and relief. Their true allegiance is a life free of rules, where they may do as they please. Because of this belief, many urchins, criminals, and other outcasts find this college as their home, singing of their personal plights.

This college’s members gather in amphitheaters or in underground slums. They carry their atmosphere with them, and as such can transform any venue into their own personal slice of limbo.

Rosetta Stone

At third level, the different languages of worlds come quickly to you. You learn 3 additional languages of your choice. If you do not already know it, you also learn the comprehend languages spell. If you do already know it, you may choose any other first level bard spell that can be cast as a ritual to add to your known spells. You may change one of these languages at a time at the end of a long rest, provided you are in an area with at least one other native speaker that you share a language with.

Distant Transmissions

Starting at 3rd level, you are able to track the holders of your inspiration, aiding them with your knowledge and boosting your own spells. While a creature holds one of your bardic inspiration die, it has advantage on all ability checks, and you always know its position relative to your own. Additionally, the range of spells you cast, as well as bard class features, is doubled.

Boosted Signal

You learn to boost your transmissions through space, allowing your to stay in contact with far away worlds, as well as allies. You may ignore the range and vision requirements to cast spells when the target of your spell holds one of your bardic inspiration die. For example, you may cast a touch spell that targets a creature with a bardic inspiration die while any distance away, even while unable to see them.

Familiar Courier

1t 14th level, a career of manning communications and connecting the distant has allowed you to see the world through your connection's eyes.

You learn the spell Find Familiar, which counts as a bard spell for you. Additionally, you gain the ability to cast spells through any creature that holds a bardic inspiration die, as well as your familiar. When you choose to percieve through the senses of your familiar, you may instead choose one of the creatures that holds one of your bardic inspiration dies.

Domain of the Godless

Godless clerics believe that there is no immortal divinity, if there is at all. They believe that ultimately, there is no higher being guiding us, so it falls to all living creatures to be the guidance we so desperately need.

Godless clerics are not all depressed madmen raving about the pointlessness of life, many heed the calling by taking agency over their own lives, and making something of themselves, rather than wait for the universe to thrust them into greatness.

For obvious reasons, these clerics no not know of any connection of theirs to the gods. How they are able to cast divine spells is up to you. Do they worship something currently alive? An ancestor? As long as it is mortal, it fills the role this domain is designed for.

Domain of Entropy

The domain of entropy worships the forces of chaos. These clerics are those who worship the forces of chaos as the guiding power of the universe. They draw divinity from the very fact that entropy is always being generated. Their manipulation of these forces is the boon that they recieve for spreading the faith by demonstration.

Circle of the Monster

Druids of this circle tap into an older source of natual energy, a more primitive source. Druids of this circle connect with monstrosities, feral beasts of immense size and power. Often these monstrosities are magically enhanced versions of beasts, allowing them to accomplish more alone, and even fend off the more dangerous adventurers.

Druids of this circle are luddites. They believe that advancement is the enemy of satisfaction in life, so they revert back to more primal behavior in their wild shape. These druids are not necessarily public proponents of this behavior, but nevertheless they are participants.

Circle of Gravity

Druids of the circle of gravity are well acquainted with the natural fundamental force they are named for. These druids have an unknown connection to the force of gravity. Some believe the druids serve as focuses for the magic that is behind the force, others believe the druids are simply hoarders of knowledge, and go out to seek that which they keep hidden. Only the elders of the circle know the truth, and they don't share that with many.

The Starfighter

Starfighters are swashbucklers of the open void. They serve as expert crew on space-fareing vessels, as well as defend these craft with delicate expertise. Starfighters are just as dangerous while weightless as they are on the ground, using the unique battlefield of outer space to their advantage.

Way of the Adaptable

Monks of the way of the adaptable live in the most remote locations in the galaxy. Rogue worlds or the odd asteroid have been known to have been discovered with a single monk on the rock, meditating and taking in the natural rhythm of all of nature. These monks change their forms to allow them to survive anything, even the cold vaccum of space itself.

Way of the Endless Void

Monks of the Endless Void become detached from reality, choosing to become one with the endless nothing between worlds. These monks emmulate the void by practicing neutrality on all stances, and are known to ignore even the most immediate of dangers. The void is dangerous, however, and improper treatment reveals the void is as deadly as it is infinite. Monks of this order practice this technique. Inert and stoic from afar, but deadly in close proximity

Oath of Falling Skies

Cataclysmic events often come from the stars. Meteors, invasions, bursts of energy, all of it is deadly to life on the worlds of greysolon, so it falls to these paladins to warn the worlds of incoming events. Paladins of this oath are known as hellsingers, the harbingers of the apocalypse. They are the final warning sign before a world is destroyed, likely with nothing the world can do about it. When an asteroid is about to destroy an inhabited moon, Paladins of the oath of falling skies are the ones who attempt to destroy it, or change its course. Failing that charge, they inform the world of their doom, and move on, answering the far out call of another world in peril. These paladins bind their identities to their weapons, ensuring that the lives of entire worlds may depend on them to do what is needed.

Tenets of the Algorithm

The Tenets of the Oath of Falling Skies are known as "Laws", and are as follows:

• Zeroth Law: A Paladin may not harm civilized life, or, by inaction, allow civilized life to come to harm.
• First Law: A Paladin may not injure civilized life, or, through inaction, allow civilized life to come to harm.
• Second Law: A Paladin must obey the orders given to them by their superiors except where such orders would conflict with the Zeroth or First laws.
• Third Law: A Paladin must protect its own existence as long as such protection does not conflict with the Zeroth, First, or Second laws.

Falling Skies Domain Spells

Channel Divinity

When you take this oath at 3rd level, you gain the following channel divinity options.

• Acheron Gavel: As an action, your imbue your weapon with the force of Acheron. Your weapon becomes adamantine for 1 minute. It deals double damage to structures and every hit is a critical hit against structures. Your weapon gains an additional +1, and your armor class increases by 1 as well.

• Expose Guilt: When speaking with a creature for 1 minute or more, you may force them to make a deception check opposed by your own insight check. If you tie or roll higher, then you become aware of any guilt the creature bears, granting you advantage on ability checks involving the target creature. This effect lasts for 10 minutes.

Aura of Adamant

Beginning at 7th level, your dedication to law sees benefits in your allies. When an allied creature within 10 ft. is struck by a critical hit, the hit becomes a normal hit.

At 18th level, the range of this aura increases to 30 feet.

Ruling of Mechanus

At 15th level, you get the final say when it comes to the fate of your allies. When you or an ally within 5 ft. fails a saving throw, you may reroll the save and must take the new result. You may use this a number of times per long rest equal to your charisma modifier.

Long Arm of the Law

At 20th level, you become an unmistakable agent of Primus, enforcing the will of law over the cosmos. Your skin takes on an adamantine appearance, and you gain the following benefits:

• You subtract your proficiency bonus from any Deception check. If you are proficient in Deception, you lose this proficiency instead. If you have expertise in Deception, you become proficient instead.
• If you were not proficient in Insight, you gain proficiency. If you are proficient, you gain expertise.
• You become tethered to the Mind of Mechanus, and gain truesight 60 ft and preventing you from being surprised.
• Your adamantine skin grants you an AC of 20 while not wearing armor.

The Starchaser

Many creatures make the space between worlds their home, and as such there are rangers who exist to understand them. Rangers of this conclave are knowledgeable and helpful guides, who specialize in sharing their power with their allies. Whether these allies are tourists looking to see space for themselves, or a trusted mount that carries the ranger through the stars is up to the ranger. Starchasers are known as ace pilots, masterful fighters, and generous allies.

The Aristocrat

What separates men from beasts are rules, and there are none finer at exploiting these rules than the aristocrat. An aristocrat knows when it is his time to twist the knife, and when someone else should take their place. Many nobles, con artist, spies, and public speakers follow this tradition and lead lives of manipulation and conspiracy while being beloved by society at large.

The Comet

Comet rogues are the blur in the edge of your vision. They emphasize using their speed and thrown weapons to frustrate, beguile, and ultimately kill their enemies. Comet rogues stay mobile, sitting just outside the reach of their enemies, daring them to get even a little bit closer.

Quantum Soul

Sometimes the bright spark that fuels the magic of a creature is unstable, radiating magic as it decays throughout time. This strange magic fills its hosts with the magic to manipulate the very fabric of reality at the smallest of scales.

A quantum soul produces unstable magic that is known to decay and affect other spells around it. Quantum Sorcerers can control this decay, and are acutely aware of their connection to the true nature of matter.

The Inevitable

You have struck a pact with a being of absolute law: an inevitable. Inevitables are responsible for the laws of the universe. For example, one of them, called Marut, is known as the inevitable death. Other inevitables include Justice or Vengeance.

The Astronomer

Some wizards dedicate themselves to understanding the magic of the cosmos. These are the sages that spend lifetimes mapping the stars, their orbits, their planets, and the magic that connects them all. Wizards of this tradition spend their nights staring into the stars, and their days preparing theories. These wizards toil endlessly to find the few things unknown, and add them to their collections.

The Nine Stars

There are nine commonly recognized systems of greysolon, each with its own unique composition and environments. Each of the worlds in these systems has separate customs of their own, and merit further inspection.

The Abyss

A primordial black hole left here for some godforsaken reason by a primordial god with a sick sense of humor. It is massive, and stands to consume the entire galaxy due if it merges with the creative chaos of limbo. Asmodeus has taken it upon himself to keep it in check with all of his resources, in exchange for certain… considerations. The abyss is a black hole that the demons emerge from. Beings from a universe with different laws of physics, they often appear grotesque as their biology adapts from whatever twisted world they came from. Asmodeus says that the abyss was a black hole that saw an event of vacuum decay between its event horizon and its singularity, thus, and entire universe was born at a more optimal energy level, but confined to the surface of the event horizon. Occasionally, some are released as the black hole loses energy slowly, resulting in the demonic scourge that we see today.

The mass of the abyss is staggering, and as such the time dilation is extreme around it. It decays rather quickly, but for the worlds near the abyss, the blood war is only just beginning.

Avernus

The first world of Hell and the front lines against the abyss. This world experiences such severe time dilation that the first battle between devils and demons is still going on. In the eyes of the devils fighting here, mere days have passed since the start of Asmodeus began this war, the dialation this close to the abyss is unknown exactly, but Asmodeus estimates that for every year that passes on this world, 10,000 pass on the material plane.

Dis

Dis is the armory of the blood war, and is mining itself hollow in order to fuel Avernus. Dispater, ruler of this realm, operates the autonomous legion of the city of dis, churning out weapons, armor, and vehicles for use against the demons. Due to the transactional nature of his business, Dispater is known to collect leverage whenever he can, and holds the largest collection of blackmail in the nine worlds. Time here flows the same as it does in Avernus, albeit slightly faster. Every eon on the material plane is 1 year here.

Minauros

Minauros is the bank of the hells. Chosen by asmodeus due to its position near Dispater, who inevitably requires the most funding, Minauros is the rotten and decrepit world of Mammon the greedy. Time here begins to decay back to normal quickly, with 1 year here being equivalent to 500 on the material plane

Phlegethos

The molten world of Phlegethos is Asmodeus’ earlies attempt to destroy a world. By turning the surface rock into lava, he sought to prevent retreat from his servants as well as draw a line in the sand against the demons. Effectively the no pass zone, rumor is that if the demons ever crossed Phlegethos, Asmodeus would finally attempt transcendence, ushering in the end of the galaxy as opposed to the demon invasion of the rest of the planes.

Stygia

The great wall on the other side of the moat that is Phlegethos is the frozen world of Stygia. A barren world that asmodeus stripped of its protective atmosphere, Stygia is an inhospitable world covered in flash frozen acid that makes up its ice. Entombed here is Levistus, ever watchful and overlooking Phlegethos. He remains here by asmodeus’ will, entombed in ice that prevents him from even averting his gaze from his post. Time here flows as it does in Phlegethos, 1 year on its surface sees about 250 pass on the material plane.

Malbolge

The prison of the nine hells, this world is the smallest and least populous. Personally, I believe asmodeus chose this world for his prison explicitly for the reason that he did not intend to take many prisoners. Additionally, due to dialation, every 125 years on the material plane, only 1 passes here. Asmodeus often includes a stay in this world in his contracts. “Only 10 years” he says, with a knowing smirk on his face. What the fine print will tell you is that those 10 years are measured from the surface, and Asmodeus now owns your soul for the next millennia. And he’s all too happy to allow you to serve your sentence on Avernus.

Maladomini

Baalzebul serves here as administrator to the nine hells, coordinating supplies to Avernus, payments to Minauros, and resources to Dis. While bureaucrats are notoriously slow to any system, the time dialation here is 62 years to 1, which means that in the eyes of the worlds he serves, Baalzebul completes his work instantaneously, no matter how long it may appear he takes.

The Matryoshka Brain of Primus

Primus is the name given to itself by the AI that upholds all law in the galaxy. While we don’t know exactly who created him, we know they must have been powerful, since the being that is primus is really an enormous matryoshka brain the size of the willing system. Primus is capable of simulating entire solar systems, and rudimentarily simulating the galaxy, with certain assumptions. Because of this power, Primus follows his directive by issuing decisions that are upheld by threat of his wrath. By either intentional design, or by dumb luck, Primus has access to the deadliest weapon in the galaxy as of now: the Acheron belt.

The Acheron Belt

Belt of chaotic rock and metal leftover from the construction of Primus. Known to prevent access to the brain of primus due to its dense, but extremely uniform motion. Primus wields it by altering the distribution of mass within the brain structure, causing parts of the Acheron belt to slingshot towards wayward targets that have violated his wishes. Due to the sheer size of many of these asteroids, as well as their adamantine composition, a barrage from this asteroid belt is almost certainly the end of anything that gets in their way. Primus assembled the belt by preventing these types of meteor strikes against developing worlds, and over the millennia he has collected uncountable numbers of these asteroids, which are all simply waiting to fall to the galaxy. It is only Primus who suspends them and protects our galaxy from external threats, so it is he who wields them in commanding our respect.

Some of the asteroids are large enough to sustain an atmosphere, leading some creatures to make their homes on the worlds of Acheron.

Buxenus

The second inhabitable world in Mechanus, Buxenus is slightly farther away from Primus than Abellio. Buxenus is the only hint we have at who created primus. The nature of the beings on Buxenus is argumentative. Every decision made by primus is reviewed here at Buxenus by legions of constructs that criticize and seek to weaken Primus. Some believe this is a way of installing an upgrade system that is driven by evolution, others believe it was an outside effort to weaken the AI Primus. Regardless, Buxenus serves as a check against the power of primus, and that check is crucial in maintaining the fairness of law, which is surely why primus keeps it.

Abellio

On the occasion that living beings must venture to appear before Primus, it is to Abellio that they venture. Abellio has every amenity one could ask for, for any race. Darkness for devils, light for angels. Water for elementals, and a breeze for the birds. It truly is a harmonious place, and it is home to Primus’ court, where trials and decisions are finalized and presented to the galaxy. It was here that Asmodeus famously defended himself against the accusations of the Allfather, and was given the ruby rod. While it is a peaceful place, there is an underlying tension. None venture here that would be tempted to break a law on its surface, even the most chaotic of creatures know that they would be struck down instantly.

The World on Fire

The closest world to the star is exposed to the most of its heat, igniting the world, and giving it the name the world of fire. The City of Brass gleams at the north pole of this world, while a sprawling underdark lies beneath the surface of the entire world. The City of brass does include this entire underdark, making the plane of fire the single largest city in the galaxy, and the second largest underdark.

The World of Ash

Shielded by a synchronous orbit from the worst of the heat, warm stellar winds blow around this planet, causing violent storms and gales to tear around the surface of the plain of air. Creatures cannot land on this planet, and those with the misfortune to lack wings or other appendages to use to control the glide are simply whisked away in the storm.

The Drowned World

After the most violent of the elements have dissipated, water collects on the planet third from the chaos star. Due to its dense adamantine core, the gravity on the plane of water is strong enough to hold oceans hundreds of miles deep in its gravity. It lacks an atmosphere due to the lack of a molten core, but the heat of the chaos star keeps it liquid until nearly the core itself.

The Petrified World

After nearly all the warmth of the star has faded, there lies one more rock. The furthest from the chaos star, water, fire, and air have not graced this world yet. An Azer from the city of brass who studied the sky here actually shared the truth about this barren rock: it’s hollow. The denizens of the plane of earth are well aware of their distance from their star, and long ago hollowed out their planet, creating the Topopolis of the earth plane. It is a sprawling underdark that mazes its way throughout the entire crust of the planet, all the way to its warm, molten core which sustains the creatures that live there.

Pandemonium Observatory

Established by Primus as a means for other worlds to study the center of the galaxy, the pandemonium observatory orbits the limbo enigma itself. Shielded from the incredible heat and chaotic energy, the station spins to generate its artificial gravity, causing its inhabitants to be able to walk on walls, ceilings, and any other surface. Gravity here simply pulls you to the nearest surface. The station itself is immense, as large as any world, and can support life indefinitely due to the ecosystem on board replacing air and producing food.

The Observatory is crucial to primus’ control over the galaxy, and in order to prevent its loss or damage, it was constructed of pure adamantine from the Acheron Belt. The adamantine can withstand the incredible strain of the limbo enigma’s explosions, insulating its inhabitants from the impacts. Additionally, due to the presence of the limbo enigma, time dilation works in the opposite direction here, with time accelerating as you approach the enigma.

The station itself runs at 0.001 B, or 1 mB. This means that for every thousandth of a year on the observatory, a year passes on the material plane. Researchers often seek immortality before venturing here to ensure that they do not simply whither and die within minutes of landing.

Ysgard

A tidal locked planet with three distinct regions. A burning world of fire known as Muspelheim, a frozen world of Ice known as Nidavellir, and a tranquil region along the center axis knows as Ysgard. Ysgard is tidal locked around the smaller of the two stars, Munin, and is home to giants of all variety, as well as the seat of Asgard, and the home of Odin.

Odin currently sleeps due to the events discussed in the mirrored wars. The short version is that he committed a powerfully evil act to oppose his ancient rival, Asmodeus. The strain placed him in a coma, where he has rested ever since, his subconscious mind still wanders, however.

The planet is divided by domain of beings, with the drow inhabiting Svartalfheim, Fire Giants inhabiting Muspelheim, and the frost giants in the frozen Jotunheim.

Krigala

Krigala is the world of perpetual day. It orbits Brux, which is suspended precariously between the twin stars. Because of its orbit, and the position of the two stars, it is always “high noon” on this world, with the occasional eclipse plunging part of the world into darkness for a brief time.

Brux

Brux is a tidal locked world between the two stars, but with a curious relationship to them. Because of the nature of the world, only a small portion of the world that is constantly in the shadow of Krigala is actually inhabitable. This section lives in a permanent dusk like eclipse that is actually quite magical to behold. The remainder of the surface is a barren desert, scorched by the twin suns barren.

Karasuthra

Karasuthra is a planet of eternal night. Its orbit is a lemniscate, which causes it to elliptically orbit both stars at different points during its year. Because of its orbit, there are two times per year that the planet is accelerated by the power of both stars and flung back into the darkness of space. These days are the solstices of the planet, and they are a time of fear and hiding as the creatures of the night take shelter for the time of the suns. Its speed of orbit is extremely slow on the outer parts, but accelerates rapidly between the stars, resulting in only a day of transition between nighttime periods. Navigation by the stars is impossible due to the changes in the night sky throughout the year.

Hades

Known as Pluton, Niflheim, or Oinos, depending on who you’re talking to, this world is a barren wasteland of nothingness. Beings in charge of entire planes use the sheer size of this mega planet to store their most egregious offenders, sentencing them to serve out an eternity on a barren world with no chance of escape. The styx comet passes through, marking the only celebrated time in this system, and tempting some to try to latch on, seeking a ride back to civilization.

Gehenna

Gehenna was a world that could have evolved to support life, but was struck with the unfortunate luck of volcanic activity. The entire surface of the world is volcanic rock, with frequent volcanoes erupting. Supervolcanoes the size of smaller worlds are common, and their eruptions spew ash into the atmosphere, plunging the world into a permanent nuclear winter. Denizens of this world have fled the surface, digging a Topopolis that is the single largest underdark in the galaxy, dwarfing even that of the world on fire. Gehenna and Hades are both about a thousand times the size of Elbaz, resulting in an underdark that dwarfs the size of our world, and is largely unexplored.

The Carceri Archipelago

The archipelago is the colloquial name given to the cloud of rogue worlds that collect around the mass of Hades and Gehenna. Some refer to these worlds as Tartarus. The worlds are categorized into six types:

1. Orthys – Worlds defined by massive mountains or spires
2. Carthys – Worlds defined by the acidic composition of their inhabitants and plants
3. Minethys – Worlds of water with little to no land
4. Colothys – Worlds defined by their many craters, canyons, and gorges cut in its surface
5. Porphatys – Worlds defined by the acidic composition of their atmosphere and geology
6. Agathys – Barren worlds with thin atmospheres and frozen cores

Each type can support some life, but it is often inhospitable. These worlds are inhabited by many who were sentenced to Hades but sought escape, only to find themselves trapped again.

Tarpeia

Tarpeia is home to the Olympian gods. Ruled by Juno, this world contains the massive Olympus Mons, a mountain so large that its peak is beyond the atmosphere of Olympus. The opposite side of the world is a smaller mountain which is ruled by the Seladrine, or elven gods. The two mountains grow out of either side of the world, causing the profile of the planet to appear diamond-like with its twin opposite peaks. Between the mountains is a shallow ocean and a barren desert that cover the low altitude regions and are largely uninhabited as far as I could tell…

Juno is the ruler of the realm, but does not impose on elven affairs unless she is invited. The elves likewise stay out of Juno’s business, expecting that when Juno is either victorious or defeated against Ysgard, it is them who will step in to rule the defeated side’s realms.

Lunia

The silver heaven is a perpetually dark world of water with starlight visible at all times. Beaches of fine sand on sparse islands are the only reprieve from water one may find here, although the oceans are not threatening to most. Creatures here find joy in gazing at the stars and floating without end, but the unexplored nature of the oceans here lead many to believe there is more here than meets the eye.

Mercuria

Gentle hills and lush valleys grace this land, dubbed the golden heaven due to the atmospheric composition twisting most light into shades of yellow and orange. It is always a golden hour here, which makes this world the picturesque home to the armies of heaven who use it as their armory and proving grounds.

Venya

Another world of beautiful scenery, the light here is suffused to a soft white, giving it the nickname the pearl heaven. It is a deceptively cold world however, with little heat making it to the surface of the planet.

Solania

The electrum heaven is a misty oasis, in which visibility is heavily restricted. Many demigods make their homes here because the worlds mists serve to separate the works of minor deities from another. If all goes well, the creations are removed and born to the universe when they leave, but if things go poorly, one can always erase and start fresh under the cover of the mists.

Mertion

A bustling world of celestials, empyreans, and the assorted hero, Metrion is the busiest of the seven heavens. It earned the name the platinum heaven due to its bustling economy, which sees more items of legendary renown pass through than any other world known. Because of this prestige, it is heavily policed, and those with malintent will find it impossible to speak on this planet.

Jovar

The Gemstone Heaven is a dense rainforest dotted with primitive tribes of celestials native to the world as well as other species introduced by Juno. The jungle holds a secret deep within its heart, it is a vault for the riches of Olympus. The world is feral by design, and would be explorers are often destroyed by the defenses. I received countless offers during my journey to scout this world or even take something with me, but I was forced to decline these offers in order to maintain the relevance of this work. Still, the temptation of the one bank in the galaxy that none have ever robbed is not one that I can ignore, thus, its legend will spread until I must revise my entry.

Chronias

This is a world that I did not dare set foot on. The radiant world of Chronias is known as the Illuminated heaven. Blinding light is emitted from its prismatic surface. The story goes that any creature who sets foot on the world has all evil and chaos burned from their soul as they merge with the perfect world of Chronias. I am not convinced that these poor souls were not simply disintegrated by the powerful radiation of the planet. My theory is that the core of this world is pure liquid radium, heated to the extreme and pressurized. The outer rock of the world may be a sort of magnifying glass, multiplying the light from below until at the surface it burns like a gamma ray burst. Regardless of your beliefs, one thing is sure: if you set foot on this world, none will ever hear from you again.

Bytopia

The twin worlds of Bytopia were created when the styx comet was first noticed. It was originally a sizeable rogue planet that was attracted by the Magnetar, but when it collided with the world of Bytopia, it split the world in two, resulting in the binary planets of Dothion and Shurrock. The two worlds orbit extremely close to one another, resulting in a transfer of gravity by any who fly more than about a mile into the air. The magnetic field produced by the magnetar causes the two planet cores to bear opposite charges, so although they orbit extremely close to one another, they can never touch.

Amoria

A world of lush forests and fertile grasslands, Amoria is very similar to Dothion. The difference between the two lies in the relationship with the magnetar, which cause extreme winds to carry around the world, rendering conversation difficult, if not impossible even at a close distance. The lush forests and valleys provide some reprieve, and are more breathtaking than any on the material plane. Dreamers who find themselves here typically dream of carefree wandering through the enchanting forests. Druids of the circle of dreams are especially attuned to this plane.

Eronia

Eronia is a mountainous realm of gorgeous gorges, monumental mountains, and beautiful buttes. The rivers and waterfalls cascade down endlessly, turning to steam often before they ever reach a pool. The high peaks are cold and snowy, but bright. Valleys are inhabited as much as any world here, which is to say not very much. Excellent world to retire on, it is after all extremely secluded. Dreamers here remain in stoic meditation regardless of their environment. Many monks and wizards use the isolation of this realm to continue their meditation and studies as their bodies sleep.

Belierin

This is my favorite world in this system by far. Many dreams on the material plane are really spiritual projected journeys on this land. The fairy tales told by the most inspired of mortals are often retellings of the events unfolded within the enchanted swamp of Belierin. Ogres find love with princesses here, and dwarves care for lost or injured wanderers. Wicked witches attempt to take control of kingdoms, but are kept in check by the spirits of faithful knights. This world is truly a wonder to behold.

Thalasia

Thalasia is the heavenly world for those who live underwater. Clear seas are illuminated by the magnetar, and are filled with vibrant life, kingdoms of coral and rock, and the echoing songs of the creatures of the deep. Another fairy tale destination, dreamers sometimes see the kingdom of Atlantis here, and pursue its glory in the material plane when they awaken. Mermaids, tritons, and sea elves all make their homes here.
