Princess Luna is the sole controller of dream magic. Some fillies and colts have shown potential to harness the same powers. She begins a summer camp for foals that will help them discover their talents while they help suffering ponies deal with their emotional baggage and daily struggles. But all is not as it seems. There is something far more sinister behind Camp Pax Æterna, something that looks to use these fresh minds for more than just relieving nightmares.

Sound Slumber, a young earth pony running from his past, stumbles upon Camp Pax Æterna deep within Whitetail Woods and learns the true nature of becoming a "Dreamscape Commando". Sound will learn that he has a gift, one that may just help him uncover the conspiracy hanging over the camp and put an end to the Dreamscape Commandos once and for all.

Dreams can be battlefields, and Sound Slumber will learn this the hard way.

A Psychonauts/MLP crossover. Dark tag applies to later chapters.
