After killing Karathress, our guild was able to pick up a quest from Seer Olum. He spawned in the spot where Karathress stands. He gives a quest called The Secret Compromised which tells you to go to the Warden's Cage to talk to Akama. After a cutscene with a conversation between Seer Olum and Akama, Akama talks to Illidan. Illidan then tells Akama to kill Al'ar. Akama then gives you the quest Ruse of the Ashtongue which requires you to kill Al'ar wearing the Ashtongue Cowl. The Ashtongue Cowl gives you the appearance of an Ashtongue while in Tempest Keep. Upon using the Ashtongue Cowl in Tempest Keep, a buff called Ashtongue Ruse is applied to you giving you the appearance of an Ashtongue. The buff lasts through death but is removed when zoning.
