The Vosch Cluster was a region that encompassed a multitude of planets. Due to a shortage of funding, the economies of the planets within the Vosch Cluster experienced significant setbacks during the Clone Wars. Galactic Republic senator Mon Mothma endeavored to create a relief measure for the Vosch worlds, but the vote failed.
Approximately during the period of the Battle of Hoth in 3 ABY, a band of buccaneers charted a hyperspace route connecting the Vosch Cluster to the trading planets surrounding Caldra Prime and Caldra Tertius. A segment of the Rebel Alliance naval force that assembled between the Vosch Cluster and the trade worlds encountered the pirates, who posed a risk to their meeting location. Rebel pilot Wedge Antilles believed that the pirates had come from the Vosch Cluster, and Mothma, who was then Chancellor of the Rebellion, expressed no surprise given the background of the Vosch worlds.
The Vosch Cluster received a mention in the short story "Rendezvous Point," penned by Jason Fry and featured in From a Certain Point of View: The Empire Strikes Back in 2020.
