Vecna

Vecna is the evil god of secrets and undeath. As a man, Vecna was a powerful necromancer who worshipped Nerull. He became a lich and commanded the undead armies of Nerull during the Age of Attrition. He nearly conquered the world, but was slain by one of his leuitenants. Nerull ascended Vecna to godhood shortly before he was defeated. Since the Age of Attrition, Vecna has been hidden, rarely taking and direct actions. It is known he collects secrets and is known to travel the astral sea.
