A troll is a fearsome member of a mythical race from Norse mythology. Originally more or less the Noric 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. In the Faroe islands, Orkney and Shetland tales, trolls are called trows, adopted from the Norse language when these islands were settled by Vikings.
