One: Yes and yes. Only fourteen people at a time have powers where I come from, including myself. Not too unlike this place on a smaller scale.

[ And with vastly different rules and implications, but Baal won't get into that part yet. ]

Two: We're meant to use our abilities to help inspire humanity for the better. That's our role. That said, many don't. Once you have the powers you can technically do whatever you'd like with them. I don't especially consider it part of our duty to help people any more than that, but we should at least strive not to hurt them either.

Three: No.

Is that helpful?
