Land of Departure

The Land of Departure is a world in Kingdom Hearts Birth by Sleep. It is the original "hub" world of Kingdom Hearts Birth by Sleep.

Settings and Areas
The Land of Departure is one of few special worlds in the Kingdom Hearts universe that is located between the Realm of Light and the Realm of Darkness. The Land of Departure has physical qualities of several major worlds from the Kingdom Hearts series. The Land of Departure is shown in artwork to be set high in grassy mountains, surrounded by flowing water. The building itself decreases in width as it reaches the ground, tall spires protruding from the roof. Two lengths of golden chain connect the castle to twin peaks. Similarly to Twilight Town, there is one major building in this world's render; the main building also bears a resemblance to Twilight Town's clock tower. Like Radiant Garden, this world also has a circular area in the middle of it, with a large building overhead.

The game's tutorial, while still controlling Ventus, takes place in the Sandou (山道). Going up into the hill leads to the Sanchou (山頂). The area before the Mountain Trail is the Zentei (前庭), where the world's Moogle Shop can be found if the player chooses to return to the Land of Departure for a limited time in the story. Beyond is Terra's, Ventus's, Aqua's and Master Eraqus's home.

The Land of Departure is also one of a select few worlds in the series that features areas that eventually cannot be accessed during later portions of the game. After Master Eraqus is killed and Master Xehanort plunges the world into darkness, the world cannot be fully revisited. The Forecourt is no longer accessible because the road leading to it has collapsed, and it is seen one last time towards the beginning of the Final Episode.

Before Kingdom Hearts Birth by Sleep
Years before the events of Birth by Sleep, after being made Keyblade Master, Eraqus became the steward of the Land of Departure while his fellow apprentice, Xehanort, became a Seeker to learn more of the worlds. By the time the two crossed paths again, they entered into a discussion where Xehanort revealed his intent to create a second Keyblade War that resulted with the two having a major falling out with Xehanort scarring Eraqus. Years after that event, after creating Vanitas from the youth who somehow survived the process, Xehanort decided to take advantage by leaving the amnesic Ventus in Eraqus's care to be trained by him alongside Terra and Aqua.

Kingdom Hearts Birth by Sleep
On the day before Terra and Aqua undergo the Mark of Mastery, they momentarily spar with Ventus before Aqua gives her fellow apprentices Wayfinders so the three of them would never be truly apart. The next day, arriving to see the exam proceedings, Xehanort rigs the test with orbs of light attacking the three Keyblade users. Despite the interference, Eraqus allowed the test to resume and names Aqua master while Terra is dismayed that he remains an apprentice. As Eraqus takes Aqua to inform her on the duties she is to take, Xehanort and Vanitas respectively manipulate Terra and Ventus into leaving the Land of Departure. As Ventus chases after Terra, Aqua is sent by Eraqus to retrieve the former.

Later, after an encounter with Xehanort presents a startling revelation, Ventus returns to the Land of Departure to confront Eraqus of his past. However, seeing that Xehanort is still acting on the scheme he unveiled to him ages ago, Eraqus resolves to kill Ventus for the good of the worlds. However, Xehanort arranged Terra to arrive to stop his master and makes his move to kill his former friend. From there, Xehanort then blasts an orb of darkness into the sky that causing the Land of Departure to become shrouded in darkness while sucking in most of the castle.

Shortly before meeting at the Keyblade Graveyard, Terra, Ventus, and Aqua each separately return to their ruined home and encounter a time-traveling Young Xehanort, who attacks each of them in turn. He vanishes after his defeat, continuing onward to the future to carry out his tasks.

After Ventus loses his heart and falls into a comatose state in the aftermath of the events at the Keyblade Graveyard, Aqua returns to the destroyed castle with Ventus on her back. She places Ventus in the middle throne and, using Eraqus's Keyblade, seals the Keyhole and reconfigures the Land of Departure into Castle Oblivion to both protect the land from any who would take advantage of it and keep Ventus safe in the Chamber of Waking.

Characters

 * Although he does not make an appearance, Eraqus and Xehanort's master is mentioned on several occasions. It is known that he was a Keyblade Master who taught the two when they were only apprentices.

Trivia

 * In Ventus's room, two of the books on his bookshelves are titled Birth by sleep and Ultimania.
 * In the original Japanese release of Kingdom Hearts Birth by Sleep, Land of Departure disappears from the world map after its destruction in each character's story, making it inaccessible in that character's save file from then on. Due to this oversight, it becomes impossible for the player to complete the Journal (and by extension the Trinity Archives) if they had not opened the Treasure Chests in that world beforehand. This was rectified in all subsequent versions, where a ruined version of the world could still be accessed after this event, which also serves as the location for the Unknown boss battle.
