Bosses

Arcurion
Horde and Alliance assaults against the Twilight's Hammer have slaughtered many of the cult's fearsome elemental ascendants. One exception is Arcurion, a formidable ice ascendant tasked to slay Thrall and retrieve the Dragon Soul. Should this twisted elemental being succeed, nothing will be able to stop Deathwing from ushering in the Hour of Twilight.
Asira Dawnslayer
Former blade-for-hire Asira Sunbright was initially leery of working for the Twilight's Hammer, but the cult's generous payments quickly won her over. In time, she succumbed to the corruptive influence of her dark employers, even going so far as to take the name Dawnslayer. As one of the cult's deadliest assassins, Asira has been called upon to exterminate Thrall and his comrades.
Archbishop Benedictus
Archbishop Benedictus is the revered leader of the Church of the Holy Light. For years, his wise guidance has been instrumental in seeing humanity through bleak times. Yet beneath his apparent benevolence lies the shocking truth that Benedictus has pledged himself to the eradication of all life on Azeroth through the agency of his dark master... Deathwing.
