Ner'zhul is a fictional character from the Warcraft universe, originally a shaman of the Shadowmoon Clan on the planet Draenor. He became a powerful figure after being manipulated by the Lich King, ultimately transforming into the first Lich King himself. His actions led to the creation of the undead Scourge, a significant force in the Warcraft lore. As the Lich King, Ner'zhul sought to conquer and control the living, spreading death and despair across the world of Azeroth. His story is central to the events of the Warcraft III game and the subsequent World of Warcraft expansions, where players confront his legacy and the consequences of his dark ambitions.
