Qelburuda

Once a proud Illithid city with structures of glasslike crystal, Qelburuda is now in ruins after the dragon Zavajounik's attacks.

Resources
This city was once filled with mind controlled slaves, who would act completely under the mind flayer's will. Since it's fall though, the slaves have broken from their bonds, and a few still reside here for lack of method to get to the surface or survive in the Underdark wilds on their own.

This city is filled with rubble of Crystal Glass (overly clear quartz rock). It also has deposits of iron and copper nearby. There were once large farms of fish and algae here, used to feed the slaves, or an illithid if hungry enough.

The Elder Brain Chamber
Located at the top of the tallest structure in the city, this chamber consists almost entirely of the vat that once held the Elder Brain. The dragon was unable to topple this structure, but managed to tear a large enough hole into the side to enter it and destroy the brain.

Fishery
Pools of water located near the slave quarters. They still contain fish, though they aren't quite as well maintained as before.

Planetarium
A ruined building that the Illithids would use to conjure illusions of the sky far above, using a device that projects a scrying onto a major illusion on the ceiling.

Slave Quarters
Rather cramped tents in one fenced courtyard in the city. A few of the surviving slaves still live here.

Arboretum
A conservatory dedicated to trees that the Illithids had chosen to grow here.

Recent History
This city has fallen recently to Zavajounik after a several day long assault against the mind flayers, using both force and psionics.
