Let me dumb it down for her.
Basically everyone here is immortal, and if not, they can reform after death, like Creatures of Night, but different still.
A Guardian is a being that was here since the birth of Time, more powerful than any other being, except Phen, Ci-Annifyr, or Pharaoh. They made the gods, the gods made mortals, and they can therefore control any and all of us, except Ci-Annifyr or Pharaoh. They are immortal.
Brycen, shut up. Darkness is clearly better and more powerful and therefore good and I'd kill the goddess of light if I were able. Being the god of darkness, I don't care about peace or balance or all that crap.
