Based on Robert Louis Stevenson's The Black Arrow.

During the War of the Sun and Moon in medieval Equestria, young Spike, a knight in training, doesn't know who he can trust when a band of outlaws accuse his guardian, Lord Tirek, of being responsible for his father's death. His suspicions grow when he meets a young colt who claims to have been kidnapped by Tirek. Soon Spike will have to choose between his duty to his guardian and his duty to his heart.
