Very cool lore and everything as usual. The whole setup made me think of an Esper from Final Fantasy 12 named "Ultima", a six-winged angel-like being. Perhaps something for Peter's Archon form?

I'm guessing Peter's element of choice will be this "Golden" element that I've mentioned in the Codex, and that you mentioned here yourself. I've named in "Aether" in one of the cards for the combat system, which can be something to keep in mind. It could also be called "light", perhaps. I don't think it should have a set name as some other elements, seeing as it is pure spirit energy or energy of the Etro (God), or something like that.

Anyway, this bubble that Peter can surround himself with and shield others, is that the same thing as the "barrier" technique in the codex? Or is it different? Also, this 'sleep' effect that you mention, how does that work specifically? Like, can it put an active combatant instantly to sleep or is it one of those things where the target is unaware of Peter's presence, to begin with, like a 'stealth' kind of thing?
