Vecna

Vecna is the evil god of lies, secrets, and the undead. He is usually depicted as a mummified, desiccated corpse missing his left hand and left eye. His many titles include the Arch-Lich, the Undying King and the Whispered One. Different cults of Vecna worship him covertly, keeping his name a secret to the general population of Khilaria until he is ready to take steps toward the domination of the gods.

History
Born a mortal wizard, he ascended to lichdom after assuming a mastery of the dark arts that no mortal had ever achieved, before or since. He is considered to be the most powerful wizard and lich to ever exist, as well as the most evil. At the height of his power, he was betrayed by his trusted lieutenant, the vampire Kas the Bloody-Handed, who destroyed Vecna's mortal body, leaving only his left hand and left eye behind. Sometime after the battle, Vecna rose to godhood and now seeks to usurp the powers and positions of all other gods until he is the only god left in existence. He is opposed by good gods and some evil gods. While he does not like Grimm, he prefers him to Orcus as the god of death. Vecna's symbol is a left hand holding an eye, to represent the two pieces of his body that were left after his mortal form was destroyed by Kas.

Relationship
Ioun is often considered to be Vecna's antithesis, because she wishes to share with the world all the knowledge that Vecna would rather keep secret.

Worshippers
New inductees into Vecna's cult are carefully groomed and often believe they are joining an obscure sect of some knowledge god, and are only told the truth when they show their willingness to do anything in pursuit of knowledge and power.

Vecna's clerics amass knowledge and secrets by any means necessary. They are spies, blackmailers and corrupters, using the knowledge they gain to hold power over others. They work to corrupt and destablize nations by turning the rulers or his advisors. The clerics of Vecna seek The Hand and Eye of Vecna, as well as the evil power they grant.

Vecna's cult is extremely secretive, and various places of Vecnan worship have been uncovered in places such as Diamond Lake, Greyhawk and Verbobonc.
