Kashyyyk, also known as Planet Wookiee C to some humans in the Core Worlds, was a wroshyr tree-covered forest planet located in the southwestern quadrant of the galaxy and the homeworld of the Wookiee species. Four millennia before the Battle of Yavin, Kashyyyk was discovered by the Czerka Corporation, who enslaved the Wookiee population and renamed the planet G5-623, later to Edean. During the Clone Wars, Kashyyyk was a member of the Galactic Republic, and endured enslavement under the Galactic Empire, the Republic’s successor. Later, during the rise of the New Republic, Kashyyyk was liberated with the help of Republic forces led by Han Solo.
The original drafts of Return of the Jedi called for the second Death Star to be built in orbit around Kashyyyk by Wookiee slave labor. It wasn’t until later drafts that George Lucas decided that the setting and characters would be changed to the forest moon of Endor and Ewoks.
The planet was introduced in 1978 in The Star Wars Holiday Special, but this is considered to be part of the Legends continuity. Kashyyyk’s first canon appearance was in 2005 in Star Wars: Episode III Revenge of the Sith. Phuket in Thailand and Guilin in China were the locations scouted for Revenge of the Sith, to capture plate photography for Kashyyyk backdrops.[source?]
Kashyyyk appeared in the non-canon animated television series LEGO Star Wars: The Freemaker Adventures episode «Peril on Kashyyyk,» which premiered on Disney XD on June 27, 2016. As in the Legends and Canon timelines, Kashyyyk is blockaded by an Imperial fleet. In the story, the Freemakers, a scavenging family, rescue the Wookiee prince Tantarra from a Trandoshan fortress island. Hitherto, the Trandoshans had been ruling Kashyyyk on the Empire’s behalf and had taken Tantarra as a hostage in order to force Tantarra’s submission. The rescue of Tantarra allows his father Chief Attiburra to launch an attack on the Trandoshans.
