To be blunt, I have an overactive imagination. An incredibly overactive imagination. Thus, the Xenogears: Prelude to Destruction series doesn't merely expand on the Xenogears game, it pulls theories from an eclectic mixture of games, animes, and my own personal stuff. This makes a section such as this necessary, because I've created not only classes of magic and dimensions, but whole technologies.
A bit of a disclaimer first, though: the TAG weapon is NOT my own creation...neither is the Planeshifter. They was first created by Mox Jet in his Planeswalkers series (and used very well, I might add). Just thought I'd get that out of the way.
