Many heroes went to Pohjola to ask daughters of Louhi them to be their wives. Louhi did not give her daughters easily. She made men to do almost impossible missions to have her daughters. One such mission was to make Sampo, a machine that would do money, crop and salt. One hero, Ilmarinen, did this machine, but still Louhi did not let her daughter to marry Ilmarinen. Ilmarinen and other heroes then stole Sampo from Louhi. Louhi attacked them. There was a big battle and Sampo was destroyed. Some pieces of Sampo drifted on sea and they came to shores of Finland. Since that they have made wealth to Finnish people.
