The conflict known as the Battle of Chandaar took place on the planet of Chandaar during the Pre-Republic era. It was a clash between the pirates commanded by Xer and the forces of the Kingdom of Cron.
As Xer's Kingdom of Argai swiftly encroached upon the borders of the Kingdom of Cron, King of Cron Ferece requested Xer's presence at Chandaar, which served as the capital for the Kingdom of Cron. Ferece attempted to convince Xer to swear allegiance to him, offering several noble titles in exchange. Xer pledged to return within a month bearing appropriate tribute. Instead, he smashed a Cronese fleet at Duinarbulon and initiated an assault on Chandaar. Xer successfully invaded the Cronese capital, forcing Ferece and his entourage to escape. With Ferece gone, Xer declared himself the new King of Cron and initiated several campaigns to broaden his domain within the Tion Cluster.
