Angels?

[berto]

If you think about it, the same could be said of the Order and whoever created the wing talisman. They were unable to comprehend that a higher force wouldn't stand against demons alongside them, so they invented the myth of angels to cope.

I don't know about that. They had a god who was a demon and they were well aware of that fact, it's not as though they need angels as higher beings to help them fight the demons.
