A troll is a supernatural being in Norse mythology and Scandinavian folklore. In origin, troll may have been a negative synonym for a jötunn (plural jötnar), a being in Norse mythology. In Old Norse sources, beings described as trolls dwell in isolated rocks, mountains, or caves, live together in small family units, and are rarely helpful to human beings.
