Xuc was an individual who lived during the Pre-Republic era. Xuc was the son of King Xer of the Kingdom of Argai, and the brother of Xic, Xim, Xom and Xil. According to the play The Pirate Prince, which was made by the Lisst'n dramatist Lyechusas, the existence of Xuc, Xil, Xom and Xic was kept secret from Xim. When Xer eventually introduced Xim to his brothers while on Argai, Xim killed Xuc, Xil, Xom and Xic, so that he wouldn't have to share Xer's wealth with them. Xer was overcome with grief, so Xim killed his father as well and then made himself the new king.
