Dark place under the earth in Greek Mythology through which the dead passed before entering Hades.

In Greek mythology Erebus (Έρεβος Erebos, "Deep blackness/darkness or shadow " from Ancient Greek Έρεβος) 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).
