Real world
In Greek mythology, the white-robed Moirae or Moerae (the Fates, often called the "Apportioners") were the personifications of destiny (Roman equivalent: Parcae, "sparing ones", or Fata). They controlled the metaphorical thread of life of every mortal and immortal from birth to death (and beyond). Even the gods feared the Moirae. The three Moirae were Clotho (Greek � "spinner"), Lachesis (Greek � "allotter" or drawer of lots), and Atropos (Greek � "inexorable" or "inevitable", sometimes called Aisa).
