The Fossegrim

A river-dwelling troll related to the Nøkken. The Fossegrim plays enchanting fiddle music like the Nøkken, but Fossegrim tend to be more mischievous and light-hearted. They have an affinity for lumber mills and waterfalls, and are known for pulling pranks on mill workers, splashing the lumberjacks or kicking logs being transported by stream. If you bring a Fossegrim a food offering, such as a large quantity of smoked meat, he’ll teach you to play the violin supernaturally well. The bigger the gift you bring, the better he’ll teach you to play.
