An ancient legend about a hunter who gets lost in the woods and encounters a creature known as Eld Fen, Old Fen, or King Wurm. The presence of Eld Fen is accompanied by darkness and fear. There are several similarities between the legend of Eld Fen and Tanis. Both exist in a forest, in a place with a strong, distinct smell. Both are found in clearings bordered by birch trees. People coming near both creatures lose a sense of direction, and both beings are associated by violence or blood of some kind. The author of the Eld Fen legend is unknown, but the story was passed down through oral tradition.
