Nøkken is a mystical troll-like creature who according to Norwegian folklore lives in the lake. He has the ability to shapeshift, and often chooses to ascend from the lake as a beautiful white horse. Nøkken is known to play majestic violin tunes to lure people closer to the water before dragging them under to feast on its pray. It is unknown what it really looks like since no one has seen it and lived, but most think it is a huge creature covered in sea plants
