Marluxia looked over to where Vexen indicated, thoughtfully. Vexen wanted to be away from the bulk of the inhabited areas, did he? That was true to form. Vexen, Zexion, and Lexaeus had been part of the basement operations in Castle Oblivion, keeping themselves separate from Marluxia, Larxene, and of course Axel up above.

However long ago that might have been. The history was patchy as to when exactly the Palace fell into the ground, and maybe someone had tried to keep using it before giving up due to the nature of the Zertinan Caverns. Marluxia certainly wouldn't have walked away from somewhere that had remained largely intact despite its fall without retrieving some things, or shoring them up for later retrieval.
