Long after the rise and fall of Nightmare Moon, the dark and mysterious servants of Princess Luna, her royal guard, battle the remaining nightmare forces to keep the waking world safe at night. But the Nightmare forces are a crafty entity, and with the population of Bat Ponies dwindling, the Luna Royal guard may face their toughest challenge yet.

A Magic scholar from Canterlort named Mystic Mind has traveled to Saddle Arabia to study Earth Pony magic, but is also on a secret mission from Princess Twilight Sparkle. However, all too soon does he realize that there is a big danger in Saddle Arabia. One that responds to the magic of Unicorns, and one that could threaten all of Equestria if not stopped.
