Deities or Gods/Goddesses are very powerful beings, usually worshipped or feared by creatures in the World.
There are only three known gods in the Overlord universe — the Mother Goddess and The Forgotten God, the latter was killed by the Third Overlord in Overlord: Raising Hell, possibly taking his place as a god.
