Hiisi is also used as a general term for demons who haunt Hittola (demon’s domain), a dreary region with charred and burned heaths and hills, not far from Pohjola, the Northland.
The Kalevala (runes 13–14) tells of the Hiisi Elk, a magic elk created by Hiisi. The hero Lemminkainen had to subdue it to win the Maiden of Pohjola as his wife. Lemminkainen defeated the Hiisi Elk by the use of magic charms and prayers. Hiisi originally referred to a sacred or sacrificial grove.
In some parts of The Kalevala the term is used for dread or haunted places. Paha Mies (evil man) is another designation of the devil in Finnish mythology. Paha Mies rules over Paha Valta, another name for hell.
