Tower of Animus/WMG

"Your world has been destroyed. I saved you. Let's all be happy here."

So what is going on in this tower, anyways?


 * One theory behind the collar colors is that the hues higher up in the rainbow are for the more powerful characters - perhaps there's some kind of failsafe in them? It would make sense with how the color swap event made the characters who climbed up in the rainbow more powerful. Supporting this is that (as far as this editor can remember) all of the Persona protagonists have violet, as do any deities in the Tower.
 * It has been speculated that the characters are having continuous out-of-body experiences. The collars are used as some sort of stability mechanism for the souls, perhaps relating to the theory above (this would explain why everyone went haywire when the collar colors were changed). Note the fact that characters revive with their body intact even if it was blown to bits, the lack of an 'astral projection' section in the research library, and the fact that the game's title translates directly to 'Tower of Souls'.
