In Scandinavian folklore, the significance of the troll lies in its representation of the unknown and its dual nature as both a fearsome antagonist and a protector of nature. Trolls are often depicted as large, misunderstood creatures living in mountains or forests, reflecting humanity's struggle against primal and untamed forces of nature. They embody the tension between civilization and wilderness, and tales of trolls serve to impart moral lessons, warn against foolishness, or illustrate the need for respect toward the natural world.
