After the apprentices banished Ansem, but before they became Nobodies, the apprentices created the Chamber of Repose within the Radiant Garden's castle. Xemnas would frequently travel to the room, as if something within it reminded him of his forgotten past. In the scene in Kingdom Hearts II Final Mix, Xemnas entered Ansem's computer room, inserted a data disk into the machine, and typed in the password "Another", after which he typed in six more passwords: the original names of the six apprentices.
This caused a passage to appear below the Heartless Manufactory, which had a long stairway spiraling down to a long hall. Inside this hall were doors electronically locked and bound with chains. At the end of the hall was a room containing a throne for Xemnas to sit on, as well as the armor and Keyblade of a warrior named Aqua. Xemnas would speak to the armor, addressing it as a "friend".
