One of the five books found in Rudeus’ childhood home.
A tale of three young prodigious swordsmen, later known as the Sword God, Water God, and North God, who meet and eventually, after various twists and turns, successfully conquer a massive labyrinth together. The authenticity of the story is uncertain. All characters mentioned in the story, apart from the three swordsmen, meet tragic fates.
It is said that the swords passed down through generations in each school of swordsmanship were obtained in that labyrinth. However, the credibility of this claim is weak, as there is no such sword in the North God Style.
