The Scandinavian näck, näkki, nøkk, nøkken, strömkarl, Grim or Fosse-Grim were male water spirits who played enchanted songs on the violin, luring women and children todrown in lakes or streams. However, not all of these spirits were necessarily malevolent; in fact, many stories exist that indicate at the very least that Fossegrim were entirely harmless to their audience and attracted not only women and children, but men as well with their sweet songs. Stories also exist wherein the Fossegrim agreed to live with a human who had fallen in love with him, but many of these stories ended with the Fossegrim returning to his home, usually a nearby waterfall or brook. Fossegrim are said to grow despondent if they do not have free, regular contact with a water source.
If properly approached, he will teach a musician to play so adeptly “that the trees dance and waterfalls stop at his music.”
