Angels

Angels are a race of immortal celestial beings from Abrahamic mythology who were created by Yahweh/Allah to be his servants. They are imbued with considerable power and the strongest of them, the Archangels, can stand toe to toe with major Olympians.

Unlike those deities however Angels aren't dependent on being worshiped or remembered by mortals or on the survival of any human civilization in order to continue existing, so they cannot "fade". Angels are one of the only supernatural beings to exist in the World of One God.

Although originally united, the First Angelic War permanently divided this race into two discrete factions. The loyalists led by Michael became known as the Angels of Paradise while the rebels led by Satan after being defeated and exiled became known as the Angels of Darkness.
