The Vampony Empire has fallen. The king and queen have been killed, and the heir to the throne gone with them. Vampony hunters have defeated the blood-sucking creatures of of the night, turning them into a thing of legend and myth. The Empire reigned for so long, causing ponies of the day to live in fear and never leave their homes at night. But when three young friends from Ponyville; a Unicorn, a Pegasus, and an Earth Pony come across a small filly one fateful night, they know a certain decision will turn their lives upside down.
