Moros

It is suggested by Roman authors that Moros was son of Erebus, primordial god of darkness.

Regardless of the presence or absence of Moros' father, this would make him the brother of the Moirai, or the Fates.

Among his other siblings are Thanatos and the Keres, death spirits who represented the physical aspects of death—Keres being the bringers of violent death and terminal sickness, while Thanatos represents a more peaceful passing.

In Prometheus Bound, the titular Titan suggests that he gave humanity the spirit Elpis, the personification of hope, in order to help them ignore the inevitability of Moros.

Weir Smyth): "A man dies not for the many wounds that pierce his breast, unless it be that life's end keep pace with death, nor by sitting on his hearth at home doth he the more escape his appointed doom (peprômenon moros).
