Erebus in Wikipedia

In Greek mythology, Erebus (pronounced /ˈɛrəbəs/), also Erebos or Erebes (Ancient Greek: Ἔρεβος, "deep darkness or shadow"), was the son of a primordial god, Chaos, and represented the personification of darkness and shadow, which filled in all the corners and crannies of the world. His name is used interchangeably with Tartarus and Hades since Erebus is often thought of as part of the underworld. Erebus married his sister Nyx (goddess of the night) and their children include: Aether (god of sky), Hemera (goddess of day), Nemesis (goddess of revenge), Charon (the Ferryman), Momus (god of satire), Geras (god of old age), Oneiroi (god of dreams), the Moirai (Fates), the Hesperides (guardians of the golden apples), Cer (goddess of death), as well as Hypnos (god of sleep) and his twin brother Thanatos (death)...
