- Were you looking for the achievement called the or the subzone called The Menagerie in The Underhold, Siege of Orgrimmar raid?
The Menagerie in Karazhan lies beyond the Broken Stair and leads directly into the Guardian's Library. This is the location of The Curator, and several other arcane guardians populate the area as well. It appears to be some sort of Museum-esque display hall with several statues.
Though the room looks normal (if not wrecked) at first glance, you will quickly notice that the wreckage is not what it seems, often floating in place as though frozen in time as it fell apart.
