Louhi is a queen of the land known as Pohjola in Finnish mythology and the mythology of Lapland. Louhi is described as a powerful witch, with the ability to change shape and weave mighty enchantments. She is also the main opponent of Väinämöinen and his group in the battle for the magical artifact Sampo in the Kalevala. She has a number of beautiful daughters, whom heroes attempt to win their hand. Louhi in true fairy tale form sets them difficult tasks to perform in order to claim such a prize.
