Erebos

Here is Nyx' husband Erebos, the primordial god of darkness. His name is also synonymous for the underworld. Nyx carries Erebos' mists of darkness across the sky each night, which is why she wears his cloak. He is the father of Aither (bright upper air) and Hemera (day). In the morning, Erebos' darkness is shattered by Hemera, who reveals the light of her husband Aither. According to some sources, he is also the father of the children whom Nyx (according to Hesiod) bare alone (Eris, Thanatos, Hypnos, the Keres, etc.).
He was easier to draw than Nyx, Gaia and Ouranos. I made him wear Nyx' belt, because she is wearing his cloak.
