Land of Departure

Land of Departure is a large, rural, Harvard-like castle built high up on a grassy mountain and is surrounded by flowing water. The castle is a golden building decorated with stained glass windows with tall spires protruding from the roof. It is the home-world of Master Eraqus, a Keyblade master who the three main protagonists of Birth by Sleep—Ventus, Terra and Aqua—train under. Terra and Aqua also take their Master Qualification Exam here, supervised by Master Eraqus and Master Xehanort. It serves as the hub world of Kingdom Hearts Birth by Sleep, similar to the role of Traverse Town in the first Kingdom Hearts game.

After the world was consumed in darkness, only the castle ruins remain on a plane somewhere in between the realms of light and dark, likely closer to the latter. Arriving to the ruins with Ventus, Aqua used her powers to reform the building into Castle Oblivion (忘却の城, Bōkyaku no Shiro?) and creates the Room of Wakening where Ventus resides
