Case File: The Muses vs. the Sirens
Case Status: Case closed. The Muses beat the Sirens in a singing contest, then plucked out the bird women's feathers and wore the feathers in their hair. The Sirens tried to file a countersuit of assault, but no one really cares what happens to the Sirens because they're always luring sailors to their deaths with their mesmerizing voices. The way we see it, the Sirens totally got what was coming to them.
