Luna is the Weird Sister of Fate.
She can be distinguished from the others by her white hair. Luna is the most mystical of the three.
Real-World Background
"Luna" is the Latin word for "moon", and also the name for the goddess of the moon in Roman mythology.

Phoebe is the Weird Sister of Grace.
She can be distinguished from the others by her blonde hair. She is supposedly more gentle and kindly than Luna and Seline (although she was just as eager for the destruction of the Avalon clan as were the other two).
Real World History
Phoebe's name comes from Greek mythology, where she was a Titaness, the mother of Leto and the grandmother of Apollo and Artemis. Her name means "the shining one." Later on, particularly in Elizabethan poetry, she came to be associated with the moon.

Seline is the Weird Sister of Vengeance, or Fury.
She can be distinguished from the others by her black hair. Seline is the most severe of the three; she was the one who told Macbeth that Gillecomgain had murdered Findlaech at Duncan’s orders, and gave him the magical ball of light which he used to slay Duncan in battle.
Real World History
Selene was the original goddess of the moon in Greek mythology (Artemis only filled that function very late in the development of classical mythology), the sister of Helios the sun-god (not to be confused with Helios the New Olympian). She was particularly noted for her romance with Endymion, whom she placed in an enchanted, unaging sleep, so that he could be her lover forever.
