Otherwise known as the Moirae, these timeless old hags weave the threads of destiny that control your life. The original spin doctors.
CLOTHO who spins the Thread of Life,
LACHESIS who allots the length of the yarn, and
ATROPOS who does the snip (the final one).
All the good and evil that befalls you is woven into your destiny and cannot be altered even one jot. You may find this a little unfair, but it's the stuff great Greek tragedies are made of.
