Sampo.

Based on Finnish mythology; Lemminkäinen woos the fair Annikki and battles the evil witch Louhi. Louhi kidnaps Annikki to compel her brother to build for her a Sampo, a magical device that creates salt, grain, and gold. When Lemminkäinen fails to recover the Sampo, Louhi steals the sun, plunging the world into frozen darkness.
