After killing Broodlord Lashlayer in the Halls of Strife, lab packs of Blackwing Technicians, Blackwing Spellbinders, Blackwing Warlocks and the occasional Death Talon Overseer line the walls. The very first pack immediately to the right of the door guards the second of the two Alchemy Labs that were found in the Old World (before the Shattering). Up until Wrath of the Lich King, alchemists were required to be within range of a lab to make flasks. The first lab was found in the original Scholomance, in Ras Frostwhisper's room in the basement. The goblin technicians are also important, as they are the only source of Elementium Ingots, necessary for the crafting of .
While clearing out the first room, keep an eye out for the first black drake boss encounter, Firemaw, who patrols the length of the room.

At the base of that semi-circular ramp, guarded by another wyrmguard pack is Master Elemental Shaper Krixix, the author of the . Finally, in the upper room is Flamegor, the last of the three drakes.
Once the drakes are dead and the last wyrmguard pack has been defeated, players may flip the lever in the next room to unleash Chromaggus, the penultimate boss encounter of Blackwing Lair.
