Following the defeat of King Ferece, Xer installed himself as the new King of Cron and launched a series of campaigns to take control of the Tion Cluster. After have conquered the complete Kingdom of Cron and defeated the Three Allied Kingdoms and eventually the Back Spiral, Xer's Empire reached its greatest extend. However, one power managed to stand against the Pirate King: the Livien League. Following a first battle at Amarin, the Liviens defeated the Cronese fleet again at Lorrad. The twin defeats infuriated Xer but he took their lesson, concluding that he had overextended himself. He retreated from the League's borders and spent the remainder of his rule forging Cron into an empire.
