What happens if an angel breeds with a demon, therianthrope, vampire or werewolf?
This is less complicated. Demons and angels, if they’ve ever had offspring (it’s difficult for a demon and an angel to engage in sex, because it’s such a powerful thing and demons can lose control and hurt the angel), would create angels. But because demons are immortal, their child would resume with aging as though their parents were both angels. As in, if the child is at least third generation on the angel side (or there has never been mortal interference), they will stop aging at eighteen, as is normal. If an angel breeds with a therianthrope, vampire, or werewolf, there is a human factor. These species are not immortal. They will affect the aging as a human would, so the human rules apply. (For example, because this is confusing, if an angel has children with a therianthrope, their children will stop aging at forty because therianthropes are entirely non-angel.
