The throne room of Insectoid queen Laz'arax in the Insectoid Hive. From here she not only rules the hive, but tends to her hatchlings as well.

You enter a cavern filled with thousands of luminescent eggs stuck to the walls. Laz'arax (LAZ-ar-rax), the Insectoid queen, patrols her nest, pausing occasionally to feed her hatchlings mashed up food from her own mouth. - The Hive (GS-ADV3)

Across the room is a large crack in the floor. It is filled with blue ichor.
