The Elder Xorn has grown fat and large off of its diet of precious gems and minerals. It's tough skin resembles that of unpolished diamonds and has grown tolerant to the extreme heat and cold of the Elemental Chaos.
When the Xorn smells magical materials, it makes a point to demand these items from adventurers, and will often bully them until they give up a suitable amount of their magical weapons, or a large amount of platinum, gold, silver and copper (in that order).
Because the Xorn has grown so fat from minerals, it is looking for a different diet to sustain itself. By hunting through the Elemental Chaos, it can occasionally find magical elements, but never enough to satisfy it's unending hunger for it. The Elder Xorn will travel to the Material Plane and hide out in dungeons and caverns, waiting for adventurers to come by.
