In "The Kalevala", Pohjola's main function is to be the home of women whom the male heroes, from the land of Kalevala, seek as wives. The Mistress of Pohjola is Louhi, an evil witch of great power. The great smith Seppo Ilmarinen forges the Sampo at her request as a payment for the hand of her daughter in marriage. The Sampo is a magic mill of plenty like the Cornucopia, which churns out abundance, but its churning lid has also been interpreted as a symbol of the celestial vault of the heavens, embedded with stars, revolving around a central axis or the pillar of the world. Other Kalevala characters also seek marriage with the daughters of Pohjola. These include the adventurer Lemminkäinen and the great wise man Väinämöinen. Louhi demands deeds similar to the forging of Sampo from them, such as shooting the Swan of Tuonela. When the proposer finally gets the daughter, weddings and great drinking and eating parties are held at the great hall of Pohjola.
