Blackwing Lair

Blackwing Lair is a 40 player raid instance and is the only place in Azeroth where players can fight against Nefarian and his minions, including the five powerful Chromatic Dragonflight drakes and their father, Deathwing the Destroyer. The entrance to Blackwing Lair can be found at the very height of Blackrock Spire and is a short 40-player raid, much like Molten Core in size. Blackwing Lair is located at the very height of Blackrock Spire. You can enter Blackwing Lair from the same place you enter Blackrock Spire, but once you're inside, you must take the left-hand spiral ramp leading upwards. The ramp will take you to a balcony that overlooks the main hall of Blackrock Spire. From here, you can either go left or right. The left-hand path leads to Blackwing Lair, while the right-hand path leads to Blackrock Depths.
