Ner'zhul

The Elder Shaman Ner'zhul was the Warchief of Draenor of the clans that remained uncaptured after the Dark Portal was destroyed in Azeroth. He was deceived into making a Blood Pact with Kil'jaeden the Deceiver; one that bound the orcs into the service of the Burning Legion. Following the Second War, he opened several portals on Draenor in an attempt to seek out new lands to escape to and conquer, but was immediately captured by Kil'jaeden. His mortal form was destroyed and his spirit was transformed into the helm of domination, known as the Lich King, which was then encased in the mystical ice of the Frozen Throne atop the Icecrown glacier in distant Northrend.
