Erebus!

In Greek mythology Erebus was the son of a primordial God, Chaos, the personification of darkness and shadow, which filled in all the corners and crannies of the world. He was the offspring of Chaos alone. He was brother of Nyx and father with her of Aether and Hemera, according to Hesiod (c. 700 BC). According to Hyginus (c. AD 0), he was the father of Geras.

According to some later legends, Erebus was part of Hades, the underworld. It was where the dead had to pass immediately after dying. After Charon ferried them across the river Acheron, they entered Tartarus, the underworld proper. Erebus was often used as a synonym for Hades, the Greek god of the underworld.

Erebus was known as the embodiment of primordial darkness, the son of Chaos (who was the void from which all things developed, known also as Darkness). According to Hesiod's Theogony, Erebus was born with Nyx (Night), and was the father of Aether (the bright upper atmosphere) and Hemera (Day). Charon, the ferry-man who took the dead over the rivers of the infernal region, is also said to be the son of Erebus and Nyx.

Later legend describes Erebus as the Infernal Region below the earth. In this version, Hades was split into two regions: Erebus, which the dead have to pass shortly after they have died, and Tartarus, the deepest region, where the Titans were imprisoned. Aristophanes' Birds says that Erebus and Nyx were also the parents of Eros, the god of love.

In short, Erebus was the son of Chaos, father of day & love and husband of the night!
