Blackwing Descent is a raid instance introduced in World of Warcraft: Cataclysm. The entrance to the raid instance is close to Nefarian's throne in Blackwing Lair and is accessible by flying to the throne on the eastern side of Blackrock Mountain. It features Nefarian as a boss, who returned from the assault on his lair and retreated further into the spire.
Little is known about Blackwing Descent at the moment. It is a part of the Blackrock Spire complex occupied by the Black dragonflight and, probably Twilight's Hammer that recently changed sides, as they were previously allied with Dark Iron dwarves inhabiting Blackrock Depths who rivaled for control of the mountain against Nefarian and his minions. However the alliance between Deathwing and Ragnaros in Mount Hyjal suggests the forces of Blackrock Mountain may be fighting as a single army.
