And then it's usually a case of "Okay, which one of you Old Gods and Monsters sent a servant to incarnate in Human Form?"
And the answer is usually Multiple Choice.
So then it's usually a case of handling a problem that Nobody knows how to deal with. And I'm an Engineer, Keri just plays a Doctor on TV and Yaori is a damn pokemon.
Granted, just the diverse perspectives help more than anything when trying to understand Magic and multiple systems...
@Motodrachen
Doesn't help that multiple system capability differs so much, both internally and externally. The best explanation I have for some of the stuff is that consciousness is independent from any personality and system members often are formed to act on mental needs (and then stay for other things to do). Perceptual and Kinesthetic fragments get particularly weird.
