Golbah hive
From Wookieepedia, the Star Wars wiki.
The Golbah hive was a Geonosian hive that built IG-227 Hailfire-class droid tanks for the InterGalactic Banking Clan and experimented with adding chemical weapons to them. When the Golbah drones revolted, the Geonosian aristocracy responded by dropping a proton bomb on them, obliterating them and creating Golbah's Pit on the former site of the spire.
