Like the other Feswe systems, the Tertiary Feswe was notable only for being located on the emergency routes blazed by Rebel scouts ahead of the Evacuation of Yavin. Rebel forces originally intended to jump from the Feswe Corridor to the Tertiary Feswe system before making their getaway to Feriae Junction and the Hydian Way. But the Empire cut off that route, forcing the Alliance to try to escape past Feswe Prime.
