Moros (Greek: Μόρος, English: doom, fate) is the god of doom. He was the one who drove mortals to their death or doom. He was the son of Nyx who created him without male intervention. In a sense he was also the spirit of depression. Moros is also the older brother and leader of the The Moirae. It was even proclaimed by the Moirae that not even Zeus could prevent his fate from becoming reality. Aeschylus describes how Prometheus saved mankind from the misery of seeing their doom (moros) with the gift of hope (Elpis). Moros' siblings Thanatos and Ker represented the physical aspects of death--Ker was the bringer of violent death and killing sickness, while Thanatos represented a peaceful, passing away.
