A hive of Geonosians active in the final decades of the Galactic Republic, the Stalgasin hive made its home in a massive spire located near the Petranaki arena in the E'y-akh Desert. Governed by an archduke who ruled the hive's political and economic business, the true leader of the hive was the hive queen, who maintained a hidden court in the Progate Temple.
Hadiss the Vaulted ruled for several years. Hadiss was slain by his successor, Poggle the Lesser, during a bloody rebellion secretly funded by Dark Lord of the Sith Darth Sidious. Poggle rode astride an acklay during the fight and eventually forced Hadiss to the ground and tore him into several pieces. Having assumed the title of Archduke, Poggle went on to expand the Geonosian Industries factories underground and pledged loyalty to the political idealist Count Dooku, leader of the fledgling separatist group, the Confederacy of Independent Systems, after the Count demonstrated fealty to the Stalgasin Queen Karina the Great.
After producing a large number of B1-Series battle droids for the Trade Federation and Techno Union, Poggle ordered the production of the B2 super battle droid to compensate for the wiry frame of their predecessors. When war finally came to the galaxy, the armies of the Confederacy and the Republic met at the Petranaki arena in 22 BBY. As the battle erupted on the surrounding plains, many Geonosians died, and the hive spire sustained great damage. Despite all this, the hive's foundries continued to mass-produce droids. Archduke Poggle retreated to the Progate Temple, the hidden palace of Queen Karina and her undead guardsmen.
Following the Clone Wars, the Stalgasin hive remained active in galactic affairs. Despite the death of Archduke Poggle on Mustafar at the hands of Darth Vader, the newly formed Galactic Empire employed Geonosian laborers and scientists to produce technologies for the Imperial Department of Military Research.
