Atropos - The third of the three Fates from Greek mythology. The first Fate, Clotho, spun the string of life (birth). The second Fate, whose name I can't remember (sorry!), measured the length of the string of life (lifespan). The third Fate, Atropos, cut the string of life when it was to end (death). Also, all three fates shared one eye between them.
So basically, We'd need two others for the other Fates as well.
