The Mauler Stronghold served as the central hub for the Maulers' operations on the planet Naboo during the era of the Galactic Civil War. This base encompassed both a modest Nabooian villa and an underground bunker complex, situated in close proximity to the city of Keren. Previously, this locale was a haven for peaceful Naboo philosophers; however, it was reduced to smoldering ruins following its seizure by the Maulers. Within the Stronghold, Mauler beast masters were responsible for training veermoks for combat, and the facility included specialized enclosures for these creatures.
In the year 1 ABY, the Royal Security Police Force launched a raid on the Mauler Stronghold, resulting in the death of the Mauler leader known as the Mauler Usurper. Concurrently, the Stronghold also became the target of an operation conducted by the Royal Marine Regiment. During these actions, caches of weapons were seized, and four key Mauler leaders were eliminated: the chief tactician Zolo Sartain, the chief of security Yarick Tempol, the assassin Xylan Kee'choap, and the mystic Walus Mutin.
Subsequently, a spacer, dispatched by Boss Rugor Nass, infiltrated the Mauler Stronghold with the mission of recovering a fragment of a shattered Gungan artifact, which had been scattered across various locations on Naboo by the Ultragungans.
In that same year, the Maulers executed a raid against the Corellian Security Force. Later, Jabba the Hutt's associate, Bruce McBrain, sent a spacer to the Mauler Stronghold. The purpose of this mission was to obtain the destruction code sequences for a CorSec Corellian Corvette, which was believed to have been stolen by the Maulers.
