The Shrieker. A tale passed down through to Griffons generation after generation. It tells of a Griffon warrior, tricked by a sorceror and transformed into a hideous, corrupted monster. The tale has been told for thousands of years. When Twilight Sparkle, Princess of Equestria, reads it, she dismisses it as a old tale.

Exceppt strange things begin to happen around Ponyville. Claw marks on trees. Mysterious sightings of three green orbs floating in the night. And scariest of all...every waxing crescent, a horrifying howl echoes through the Everfree, belonging to no known animal or being.

Despite her disbelief, Twilight investigates, and soon finds herself face-to-face with a tale that just might be true after all...
