Ahch-To is an aquatic planet with numerous islands which served as the origin for the Jedi and is the location of the first Jedi Temple. It was also home to Jedi Master Luke Skywalker, who went into self-exile seeking the Ahch-To Jedi Temple after most his new generation of Jedi Knights were killed by Kylo Ren and the rest of the Knights of Ren.
- Ahch-To Jedi Temple: A Jedi Temple is hidden on Ahch-To. It was the first of many temples built throughout the galaxy, it was established and maintained by the Jedi Order; it is one of the few Jedi Temples that were not destroyed by the Galactic Empire in the Jedi Purge or the Galactic Civil War. Based on what had been seen in The Force Awakens, it looks like the Ahch-To Jedi Temple had been abandoned by the Jedi Order even before the Clone Wars and the Jedi Purge respectively began.
