Roshyk was a Wookiee who alongside half a dozen other Wookiees including Hrrgn and Kirratha escaped from the planet Kessel after being enslaved by the Galactic Empire. After escaping the group began to work as mercenaries who cared little for the politics of the New Republic. When an opportunity arose for the smugglers Han Solo and Chewbacca to liberate the Wookiee homeworld Kashyyyk, Solo asked Chewbacca if he could get in contact with Roshyk and the others.
