Igluik - World Parent

Long ago a great catastrophe caused the world's supporting pillars to collapse and destroy the earth. Two men emerged full-grown from hummocks of earth. They married each other, and one became heavy with child. The other man sang a magic song, which caused the pregnant man's penis to divide, he then became a
woman and gave birth to a girl child. The mother and father giants cared for the child who grew large and fiercely loved meat. One night she bit into her parents limbs while they slept. They awoke in horror as she tried to bite them again. They took her in a umiak far out into the deepest sea, where they pushed her into the water. She clung to the side of the boat, so they cut off her fingers. The fingers became whales, seals, and shoals of fish. The giant parents were afraid of their child and they rowed away into the night. The giant girl became the demon girl Sedna, the Great Mother of sea creatures. She causes storms and governs the migrations of her sea creature children.
