​Dusk Shine is a young man gripped by a singular, burning ambition: to carve his name into the annals of history as a legendary sorcerer. Obsessed with achieving the esteemed status of a High Sorcerer like his idol, the great Star Swirl the Bearded, he pushes himself to the limit as the direct protégé of the ruler of the kingdom, Princess Celestia.
​His orderly world is turned upside down during a routine visit to the library. He discovers a mysterious book that, at first glance, appears to be a simple children's storybook. However, Dusk quickly realizes the tome holds a significance far greater than mere fiction—it is a harbinger of a darkness long forgotten.
As the kingdom prepares for the high-stakes "Sunset Celebration," the ancient prophecy of Nightmare Moon’s return begins to manifest. Dusk is tasked with overseeing the event and confronting the Queen of the Night, but he soon finds he isn't the only one interested in the mission.
