In Greek mythology, the Keres /ˈkɪriːz/ (Κῆρες), singular Ker /ˈkɜr/ (Κήρ), were female death-spirits. The Keres were daughters of Nyx, and as such the sisters of the Fates – collectively known as the Moirai, the names of the three Moirai being Atropos, Clotho and Lachesis. Some later authorities, such as Cicero, called them by a Latin name, Tenebrae, or the Darknesses, and named them daughters of Erebus and Nyx. Thanks
