Xyn, Torvin
this was the alias assumed by a Yuuzhan Vong warrior, who managed to infiltrate the Imperial military and spy on the activities of the Imperial Remnant. He was discovered shortly after the Battle of Bastion, as the remaining Imperial fleet massed to defend Borosk. Jacen Solo and his specially-programmed MSE-6 mouse droids identified Xyn and several other "Imperial officers" as Yuuzhan Vong in disguise, and called them to a "staff meeting" aboard the Right to Rule. Without a way to escape, Torvin Xyn removed his ooglith masquer and attacked. When a squadron of stormtroopers were called in as support, Jacen managed to take advantage of the Yuuzhan Vong's surprise to slice through the alien's chest with his lightsaber.
