Vorlishar is the Lord of Chaos, and is arguably the greatest Chaos god of the Empire. His worship is strictly outlawed, but even amongst the civilized cities of Blackfire he has a strong following who practice his rites in secret and who strive to bring about a return of the powers of Chaos and anarchy to dominance in the realm. Outside of the enclaves of civilization, Vorlishar has a strong following amongst the evil races, who see the power of this dark deity as a means to gain their own ascendancy. The dark elves are particularly fond of the Mad God. Cults of Vorlishar are completely self serving, and almost never work together.

Vorlishar is completely insane, and wholly unpredictable. He typically does not grant powers or priveliges to those who invoke his name, but sometimes one of his worshippers develops vast abilities for destruction. The only thing that can be truly expected of Vorlishar is that he delights in destruction and the disruption of order. When he appears on the mortal plane, his semblance could be anything, but blight and decay follows where he treads. The plants he walks upon wither and die, buildings he touches crumble in an instant, and pure water touched by his shadow is made putrid and unclean.
