Also, I feel like maybe we should collaborate a little more and put some effort into the history, now that we've decided there's reincarnation and hearts lost going on.

Like, how did Amaterasu lose her heart? Why are we 999 year old triplets? Surely Eos isn't only 999 years old. Well, maybe, I guess I don't know?

If we were just unrelated Gods to Eos, that would fly, or angels born under the aspects of those gods sure, but if we're supposed to actually be said legendary beings, there's a few lingering questions.
