This story was about one of the main characters of the epos Kalevala - Lemminkäinen, a powerful sorcerer and a carefree guy who often challenged fate. However, fate was rarely favorable to him - according to one of his assignments, Lemminkäinen had to get a sacred bird - a swan - from the afterlife kingdom. The killing of a bird was punishable by death and the sorcerer overtook an evil fate - when the old man, which was offended by Lemminkäinen, created a water snake and killed young sorceer.
