The Warlock Lord is the principal villain of The Sword of Shannara. He was formerly the Druid Brona. Brona desired power. He delved deeply and quickly into forbidden knowledge and was corrupted by the dark power of Ildatch, a book of magic said to have a mind of its own. His first attempt to subvert the Four Lands resulted in the First War of the Races, in which he led an army of Men. He and his followers were defeated by the combined forces of the other races, led by the Druid Council. Brona was never found and presumed dead.
