The Blue Light
This classic German fairy tale, collected by the Brothers Grimm, tells of a discharged soldier who discovers a magical blue light in a witch's well and gains the power to summon a powerful dwarf servant. When the King dismisses and abandons him, the soldier uses his newfound magical ability to seek revenge—a quest that tests both the King's cunning and the soldier's moral resolve. Readers should expect a traditional folktale structure with magical elements, clever plotting, and the ultimate triumph of the wronged protagonist.
