This quest chain involves sowing confusion among the Burning Legion at Forge Camp: Anger in Blade's Edge Mountains. This quest chain starts when you find a [Damaged Mask] off of a defeated Fel Corrupter. (See Culling the Wild.) While one will eventually discover that the Burning Legion is also on the plateaus of Ogri'la, the Burning Legion presence at Forge Camp: Anger is the only one accessible without a flying mount.
