The base on Arda I for the Rebel Alliance was founded by the Ardan resistance some years before the Battle of Yavin, later becoming an important Alliance position within the Gordian Reach sector.
This base was situated inside the Gauntlet, a lengthy, winding canyon located on Arda I. The main hangar was integrated into the canyon's cave system, spanning two kilometers in width. Living quarters included dormitories along with numerous rooms designated for officers. During downtime, the mess hall functioned as a recreational lounge. Additionally, the base featured a medbay, a command and control center, an armory, and a secondary hangar that accommodated at least two Kihraxz assault fighters.
Ran Niall led the Ardan resistance in establishing the base a number of years preceding the Battle of Yavin, which subsequently evolved into a pivotal Rebel Alliance outpost. The location of the base was compromised by the turncoat Var Narek several weeks following the Battle of Yavin. The Galactic Empire dispatched a substantial force to attack the base. Its ultimate destruction occurred when the Rebels intentionally disabled the primary power core.
The Arda I base is featured in Onslaught at Arda I, a roleplaying game adventure from Fantasy Flight Games published in 2014.
