The seven ravens

a father who, in a fit of anger, curses his seven sons, turning them into ravens after they accidentally break a jug while fetching water for their newborn baby sister's baptism. Years later, the determined sister embarks on a quest to find and free them, journeying to the sun, moon, and stars, eventually sacrificing a finger to enter the Glass Mountain where they are imprisoned, and breaking the curse by leaving a ring in their food.
