In the magical world of Equestria, the land is divided and the realms are at war. With Princess Luna on the verge of being defeated by her sister, Princess Celestia, she attempts a long forgotten spell. It is one that calls forth a hero in times of great need and what appears is something that Luna did not expect.

A human by the name of Aerin Skyheart is called forth. Can he truly make a difference in a world where the blade rules above all else?

((Anthro ponies, humans and a Dog Days crossover? Oh my!))
