i noticed recently that there is a face-like symbol in the middle of castle oblivion that is similar to the face-like symbol that appears on the handguard of MX's keyblade. perhaps not exactly the same, sure, but i think it reinforces a connection here. first of all, there is the visual similarity (which I actually dont see much) between Land of Departure and CO that so many have noted, which would connect the realms of the two keyblade masters if CO were to be MX's castle. second, there is the obvious insinuation that the Chamber of Awakening that most likely houses Ven is inside CO somewhere, which would make sense if MX or whoever were to place him there and so maybe xemnas somewhat remembered him being there which is why he told the Org. to look there? who knows. anyways, im just saying that since they usually dont reveal the main ending world in trailers (and sunset horizons would prolly be a boring ending world anyways if it's just desert), perhaps the real ending world will be MX's possible lair, Castle Oblivion. what do you think?
