A conflict occurred on the planet Brigia during the Pre-Republic era. This battle involved the Kingdom of Cron, led by Pirate King Xer, and the forces of the Back Spiral.
After the defeat of King Ferece, Xer took the throne, becoming the new King of Cron. He then initiated a number of military operations with the goal of dominating the Tion Cluster. Once he had finished conquering the entirety of the Kingdom of Cron and had defeated the Three Allied Kingdoms, Xer set his sights on the territories of the Back Spiral. Following successful battles at Caluula and Brigia, Xer proceeded towards Tion.
