Um, Dan, you got one thing wrong. (Actually, more than one, as I'm not turning 42)...

The SC is inside Mata Nui. I quote from the Bionicle Wiki's article:

"The mainland was underground, on the same level as Metru Nui."

Besides, it appears in Reign of Shadows, which would be impossible if it were on Aqua Magna.
