D&d Cult Of Vecna. He was once a mortal king who transformed into an undead lich in order to accumulate limitless magical power. The hand is a mummified and shriveled left extremity.
His skin was weathered and decayed pulled taut against his skeletal frame. Vecna also known as the Whispered One the Undying King and the Lord of the Rotted Tower was a powerful mortal-born archlich who achieved godhood. The Cult of Vecna is a secretive group that is devoted to the demigod Vecna master of lies of destruction.
He was first introduced in the World of Greyhawk DD setting.
Vecna was created by Brian Blume for the original DD supplement Eldritch Wizardry in 1976. So she has her pre-lich symbol of a red circle with a red cross in it. He is usually depicted as a mummified desiccated corpse missing his left hand and left eye. The Cult of Vecna was founded by a group of mages from the city of Neverwinter and led by Gabrielle Revvan.
