Belial

Belial is one of the most powerful and feared Dukes of Hell. His domain encompasses the seed of darkness that lies within the hearts of men. Corruption of the pure is his favorite sport, and the passtime of his servents. Belial has corrupted virtueous Preists into slavering cultists, and great kings into tyrants. His greatest acheivment in the eyes of history was the conversion of the Champion of Pelor, Sif, to the worship of Kuthian, causing the downfall of the city of Northwatch to an army of Orcs. All men are evil, teaches Belial. They just don't know it yet.

Domain
Belial is sealed within the layer of Baator known as Minauros. Minauros is a dark and twisted version of a once great and prosperous kingdom, where the trees look eerily like human forms, and where the houses look like they are locked in an eternal scream.

Summoning
In order to summon an avatar of Belial, a pentagram must be drawn on the floor. Within this pentagram, a black cloak must be placed, along with a paper with the word "virtue" written on it. This paper must be burned. Then, the follwoing incantation must be chanted:

"Oh, Belial, knower of Souls, I call thee to earth! I have seen the darkness, and have hearkened to it! I bend my knee to thee, that I might serve thee, and know more of that wonderous dark which makes up my soul. Allow me to give in to this Blackness!"
