The Fifth Order introduces three Demi-gods into the mix.
Aka Birth or Eileithyia
Sixth was God's first creation after Satan. They are a non-binary demi-god, with the pronouns of She/Her.
Sixth specializes in the creation of new life, so they are paralleled with goddesses of childbirth and fertility. Sixth's remaining job is to help guide souls into new bodies, as well as give a seed of spirit to every being.
Aka Mother Nature or Persephone
Deo is the daughter of Sixth, the only demi-god not made by God himself. She instead was sculpted by Sixth to take over some of Sixth's duties as a demi-god.
Deo is very closely paralleled in many ways to the greek goddess Persephone, especially in Order 6 with the introduction of the Creation Myth.
Aka The Grim Reaper or Thanatos
Death was originally created by God for population control. Death is another non-binary god, their pronouns are He/Him/His.
The Grim Reaper is not as bad as he is depicted often in pop culture and the like. The grim reaper does not kill anyone but instead finds those who just died. Upon a person's death, the grim reaper is the one that keeps them company on their journey to Hell or Heaven, he will answer as many questions as he can that you may have. The Grim Reaper cannot force you to go to Heaven or Hell, which it is in cases where people refuse to go that they become a ghost.
