Mythology
Sedna is the Inuit Goddess of the Sea. She lives at the bottom of the ocean with the seals and whales. Hunters have a great respect for her. Sedna's anger against man is what drums up the violent seas. Shaman from the world above must swim down to her to comb her long, black and tangled hair. This calms Sedna down, and she releases her mammals to allow the Inuit to eat from the bounty of the sea.
