The Tertiary Feswe system, a star system, existed within the Gordian Reach region of the Outer Rim Territories.
The Tertiary Feswe system, similar to the other Feswe systems, gained attention primarily due to its position along the emergency routes established by Rebel scouts preceding the Evacuation of Yavin. Initially, the Rebel forces planned to execute a jump from the Feswe Corridor directly into the Tertiary Feswe system, aiming to continue their escape towards Feriae Junction and the Hydian Way. However, the Empire intercepted and blocked this specific path, which compelled the Alliance to attempt their escape by navigating past Feswe Prime.
