We will be using the following optional rules from various sources.
Some characters in Birthright come to rule their own domains. These characters are known as regents. Their divine bloodlines give them a mystical connection to their holdings, letting them shape the domain as they will.
Spellcasting regents can channel the power of the land or of the faithful into powerful ritual magic. This involves taking a domain action to cast a realm spell. In order to cast a realm spell, the regent must have access to minimum level of source or temple holdings in the province in which the spell is being cast and will take effect. Druids, sorcerers, and wizards can forge ley lines to allow them to tap into their sources at a distance, though they still need a ley line terminating in the province where they intend to cast the spell. Most realm spells also have a cost in RP and GB.
Most, but not all, of the creatures from *Dungeons & Dragons* can be found in Cerilia. However, some monsters do not exist or differ from their familiar forms.
Dragons on Cerilia are powerful creatures of legend. Since humans arrived on the continent over 1500 years ago, fewer than two dozen dragons have been known to exist, and scholars believe that only a half dozen or so are still alive. Even the youngest of them is many centuries old.
