Roshyk, a Wookiee, managed to flee the planet Kessel after the Galactic Empire had enslaved him. He was joined in his escape by approximately six other Wookiees, including Hrrgn and Kirratha. Following their escape, the group started operating as mercenaries with minimal interest in the politics of the New Republic. When Han Solo and [Chewbacca], who were smugglers, found an opportunity to liberate the Wookiee homeworld Kashyyyk, Solo inquired with Chewbacca about the possibility of reaching out to Roshyk and his companions.
