The Watcher of the Mists
The Prince of Darkness is the only evil deity whose worship is tolerated in most civilized areas. It is said that he created the concept of contracts, and was instrumental in sealing the insane god Rovagug the Destroyer at the beginning of time after Sarenrae had subdued it. The Church of Asmodeus teaches strict discipline and holds that it is the right of the strong to rule over the weak. Priests of Asmodeus delight in drafting complex contracts that, while seemingly fair, actually favor one party over another, or include clauses that are seemingly benign but can cause ruin if acted upon.
The Church of Asmodeus is the state religion of Cheliax.
