Lich King

The Lich King is the master and lord of the Scourge which he ruled telepathically through the Helm of Domination from his Frozen Throne atop Icecrown Citadel.
Kil'jaeden the Deceiver created the original Lich King from the spirit of the orc shaman Ner'zhul for the purpose of raising an undead army to weaken Azeroth in preparation for the Burning Legion's invasion. Initially trapped within the Frozen Throne with Frostmourne, the Lich King eventually betrayed Kil'jaeden and merged with the human Arthas Menethil. Wowpedia -
