The arrival of the Twilight's Hammer, a sinister cult who worshipped Azeroth's malefic Old Gods, seduced by Deathwing's thirst for absolute domination over Azeroth, has claimed the Twilight Highlands as its base of operations. The black dragonflight has driven off the agents of the red dragonflight who guarded Grim Batol so that it may be used as a fortress for training Deathwing's minions. The halls of Grim Batol run so deep into the highlands that it is unknown to what twisted end the Twilight's Hammer is using this doomed dwarven marvel.

Called to action by the red dragonflight in the Twilight Highlands, adventurers will be charged with putting a decisive end to the foul machinations developing within. The army within is lead by General Umbris.

Grim Batol will be an instance hub in the upcoming Cataclysm expansion. Now part of the new the Twilight Highlands zone, it will contain both a 5-man dungeon and a raid.

Instances

• Level 85 5-man Grim Batol (instance)
• Level 85 raid Bastion of Twilight
