Moros (Greek: Μόρος, English: Morrow) is the God of doom.
He manifested as a shapeless being that 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. Moros wrote the destination; the Fates made sure that it came true, and shortly afterwards, chaos was integrated into the cosmos for all beings that could escape on the occasion of their own destiny. It was even proclaimed by the Moirae that not even Zeus could question Moros (destiny), who like his mother, Nyx, was invisible and dark. To break with destiny was to reintroduce Chaos into the world. Even if Zeus issued a decree or made a promise he later regretted, he could not then change his decree because it was destiny. In which case, he was the only force that Zeus dreaded. Because of this, Moros was also considered to be omnipotent, omniscient, and omnipresent. 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 were the bringers of violent death and killing sickness, while Thanatos represented a peaceful, passing away. In other terms Thanatos represented natural death.
- Ever since Moros was concealed from the perception of humanity, he was hardly mentioned in mythology. He is briefly mentioned when Prometheus was telling the chorus about the gift of hope he and Elpis set in motion. From that point on as his younger sisters carried on larger roles in manipulating fate, though he still existed as a force of destiny.
- Moros' name is also the origin for the word "morose", meaning sullen, ill-humored or gloomy. The word is used to describe the victims of whom he revealed their fates to.
