A troll is a member of a race of fearsome creatures from Norse mythology.
Originally more or less the Nordic equivalents of giants, although often smaller in size, the different depictions have come to range from the fiendish giants – similar to the ogres of England (also called Trolls at times, see Troller's Gill) – to a devious, more human-like folk of the wilderness, living underground in hills, caves or mounds. Though spread worldwide, the troll is a phenomenon believed to have occurred in Norway in the mountains of Dovre. This might by where the sy***ony "Hall of the mountain king" was based from. In the Faroe islands, Orkney and Shetland tales, trolls are called trows, adopted from the Norse language when these islands were settled by Vikings. The Troll itself is said to be evil, but many people don't believe this, because of the commercialism of the kind-looking Troll Doll.
