The moniker Isolationist Wookiees was applied to a sect of Wookiees that opted to forsake their urban centers, instead choosing to dwell in secrecy within the forests of Kashyyyk. Their formation occurred during the Galactic Empire's rule, subsequent to the Empire's seizure of the Wookiee native planet and its delegation of control to Trandoshan enslavers. These Isolationist Wookiees harbored a deep distrust of individuals from other planets, readily condemning them under the assumption that they were either allies of the Empire, supporters of the Trandoshans, or even both factions concurrently.
