Cho'Gall (17 January 2011)

Cho'gall, Initiate of the Fifth Circle of the Shadow Council and Chieftain of the Twilight's Hammer clan, is a two-headed ogre and the first of the ogre magi. He was the last adversary inside Bastion of Twilight.
Using both warlock and mage spells, Cho'gall tried to crush the wolves with no mercy. Later on the mutated ogre started using abilities granted by C'thun; tentacles, spilled blood of the old god, etc. In the end, it was another victorious night for the pack. The bastion was fully cleared.
