A troll is a fearsome member of a mythical anthropomorph race from Scandinavia, mostly Norway. Their role ranges from fiendish giants – similar to the ogres of England – to a devious, more human-like folk of the wilderness, living underground in hills, caves or mounds.depending on the type of troll (forest or mountain), the forest sometimes likes to hide or hybernate in deep springs or rivers. The mountain troll mostly likes to house in mounds or hills. In Orkney and Shetland tales, trolls are called trows,trows, adopted from the Norse language when these islands were settled by Vikings.

Nordic literature, art and music from the romantic era and onwards has adapted trolls in various manners – often in the form of an aboriginal race, endowed with oversized ears and noses. From here, as well as from Scandinavian fairy tales such as Three Billy Goats Gruff, trolls have achieved international recognition, and in modern fantasy literature and role-playing games, trolls are featured to the extent of being stock characters.
