Xyrias Undea was a Corellian Security Force rogue who operated as a female Human during the era of the Galactic Civil War. Her existence unfolded during that time.
Following the Battle of Yavin, Xyrias Undea took the lead of a band of Rogue CorSec criminals situated in Doaba Guerfel. In 1 ABY, they began to bother Gwhirrye Baric, a minor criminal engaged in a spice operation from a small medical facility within Doaba Guerfel. An operative of CorSec, reporting to Captain Vitala Baize, consented to aid Gwhirrye with his predicament, ultimately eliminating several Rogue CorSec offenders, with Xyrias Undea among them. Consequently, Gwhirrye Baric came to an agreement to support CorSec in their investigation concerning the Chirq Council.
Xyrias Undea functioned as a non-player character featured in the video game Star Wars Galaxies from 2003, a massively multiplayer online roleplaying game. This game was created by Sony Online Entertainment and brought to the public by LucasArts. The game ceased operations on December 15, 2011. Xyrias Undea's presence was integrated into the game through an update titled "Chapter 1: The Corellian Captives," which was released on June 8, 2006.
