Snow people

Snow people are a population of polis that live in the polar region. They have evolved a form of hypertrichosis that gives them a white coat of fur. Like polar bears' fur, this keeps them warm in freezing weather without needing clothes, though many are fond of accessories.

Creation myth
For snow thou art...

Their creation myth holds that God created the first few snow people from snow, tree branches, and a cylindrical hat to act as a spirit conduit. A year of wearing the hat and eating food caused cells to replace the snow, allowing a snow person to pass the hat onto another. This established the initial population until the hat stopped working.

Though such a hat may never have existed (bah humbug), to this day, many snow people wear a top hat in honor of this myth.
