During the Galactic Civil War, the Galactic Empire utilized the Imperial Stronghold as a military installation on the planet of Corellia.
This Stronghold, a Galactic Empire base during the Galactic Civil War, was situated in the Suntir Plains, located south of Dregan's Pike on Corellia, a planet.
The Stronghold's infrastructure included five watch towers, three landing pads, and seven single-story, bunker-like structures. A metal wall enclosed most of the Stronghold. It was patrolled and manned by stormtroopers, Imperial troopers, non-commissioned officers, Triumphant-class dark troopers, as well as specialized stormtroopers such as assault troopers and stormtrooper medics. The Stronghold also housed two TIE/LN starfighters, one TIE/sa bomber, and a single Lambda-class T-4a shuttle, with TIE pilots among its personnel. An Imperial Surface Marshal had their office located inside one of the Stronghold's buildings.
This base was constructed and operated by the Galactic Empire during the Galactic Civil War, which was fought against the Alliance to Restore the Republic. The Empire exerted considerable effort in building this strategic outpost.
Following the Battle of Yavin, very few Corellians were aware of the base's precise location or its intended function. A journalist hailing from Tyrena attempted an investigation of the Stronghold, but Imperial forces turned him away. Subsequently, the eager journalist sought a spacer to infiltrate the base and uncover its purpose. Lock Vlash, a former Follower of Nyax, was also among those who knew of the base's existence.
By 1 ABY, the Imperial Stronghold had evolved into a highly contested area during the Galactic Civil War, with numerous battles fought between Imperial and Rebel forces for control of the base. While Rebel forces succeeded in capturing the base on several occasions, Imperial forces consistently managed to reclaim it. Around that time, a spacer managed to infiltrate the Stronghold and pilfered boots from Scout trooper armor.
The 2003 video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game created by Sony Online Entertainment and released by LucasArts, featured the Imperial Stronghold prior to the game's shutdown on December 15, 2011. The "Publish 1" update, released on August 3, 2003, transformed the Imperial Stronghold into a "Factional NPC Base." Rebel player groups could then engage Imperial NPCs and complete various objectives to seize control of the base.
