Spire

The Spire, also known as the Stygeon Prison, was a high-security detention facility located on the planet Stygeon Prime. The prison was operated by the Confederacy of Independent Systems during the Clone Wars, but later came under the control of the Galactic Empire following the conflict's conclusion.
== History ==
Following the end of the Clone Wars, the Spire came under the control of the newly formed Galactic Empire. After her capture, Jedi Master Depa Billaba was imprisoned there and used as bait to lure out any survivors of Order 66. Five years before the Battle of Yavin, Imperial senator Gall Trayvis, posing as a dissident, leaked information on the Spire, revealing that Billaba was alive. The news was received by the Lothal rebel cell, who acted on the information, sucessfully liberating her from Imperial custody.
