Four thousand years ago, Starswirl the Bearded accidentally created a race of immortal ponies with a dangerous allergy to sunlight. When one of them escapes their prison a thousand years later, he becomes Starswirl's apprentice in order to rescue his family from a tyrannical alicorn king. But when the darkness that's been festering inside of them for centuries finally appears, how will they defeat it? And when they are forced into the forefront of Equestrian history, will they even want to?
