Kingudamu hâtsu: Bâsu bai surîpu2010

[Aqua is in the ruins of the Land of Departure, remembering her final lesson]

Master Eraqus:
Now that you are a Master, there is one secret in particular you must know. Should anything happen to me, and you find the legion of darkness at our doorstep, I ask that you take my Keyblade and use it to lock this land away.

Aqua:
What?

Master Eraqus:
Generations of Keyblade Masters have been charged with keeping this land safe. Light and darkness exist in balance here, and there are those who would abuse such neutral ground. This is why our predecessors devised a certain... trick.

[Aqua hold out the Master's Key, revealing the keyhole]

Master Eraqus:
[v.o] Just use the key, and this land will be transformed. From that day forward, all who visit this land will be lost to oblivion, none ever able to solve the mystery. None, Aqua, except you.

[the Land of the Depature transforms into Castle Oblivion]
