Haethen Kaul is the leader of the Twilight's Hammer clan in the Masters' Gate area of Deepholm, hovering in a blue pillar of light in the rocky overlook upon the Twilight Terrace[[:File:|[, ]]]. He directs his followers in unearthing the waygate that leads to Uldum, paving the way for Deathwing to enter and claim a powerful titan weapon. Even so, he reminds his followers that they "serve a higher power", presumably the Old Gods. Haethen is also siphoning the power from several bound elementals imprisoned by his cultists.
