Ahch-To

In the decades after the Galactic Civil War, an aquatic planet became home to Jedi Master Luke Skywalker, who went into exile after his new generation of Jedi were killed by Kylo Ren. The aquatic world, which had numerous islands, was the location of the first Jedi Temple, which Skywalker sought out during his exile. After the Resistance pieced together two map fragments to reveal Skywalker's location, Rey traveled to this world in order to find Skywalker.
