Ul'haik Hadanot is a high elf and the co-leader of the Cult of the Damned alongside Pai Stormbringer. He is tall for an elf, with a thin frame. His hair and skin has darkened almost to pitch black due to his fevered study of magic. He had been a sequestered and unfriendly mage dedicated only to his studies. He preferred his books over contact with other elves, and did not mourn them when Dalaran fell. Instead of feeling disgust at the invading undead, he felt a sense of awe at their power, and surrendered to them willingly. Kel'Thuzad recognized his ambition and quickly put him in charge of the cult, directing mages within and researching dark magic to further the spread of the undead. He prefers to keep to himself and study dark magic on his own, but finds himself in meetings with Pai and the lich, discussing the deeper aspects of necromancy and plans of attacks to get more cult members to move the Scourge further south. He secretly detests Pai and her cheerful attitude and plots to kill her and render her body so damaged with magic that she will be unable to rise as undead.
