The Ghrag Mercenaries served as adversaries to the Civilian Protection Guild, notably to Eyma, a Guild member, on the Wookiee's planet of origin, Kashyyyk. Their operational base was located within the Tyyyn Nebula. During 1 ABY, the Ghrag pilfered a CR90 corvette belonging to the Civilian Protection Agency, but Eyma dispatched a team of spacers who successfully recovered it from them.
During space engagements, Ghrag pilots utilized Kihraxz assault fighters, Ixiyen-class fast attack crafts, Rihkxyrk assault fighters and X4 Gunships as their primary vessels.
The Ghrag Mercenaries were featured in the 2003 video game Star Wars Galaxies. This massively multiplayer online roleplaying game was created by Sony Online Entertainment and distributed by LucasArts, before its discontinuation on December 15, 2011.
