One of the best known theories (E= mc²) says that if a body, made of flesh or something else, exceeds the speed of light, it will turn into energy. But what scientists don't know is that instead of transforming the body into a mass of particles, it can perform long journeys through a instantaneous displacement portal (or wormhole). Ethan Gray try it and finds himself stuck very far from Earth, on a world full of colorful ponies. But getting back on his homeworld will not be easy, especially if he's running out of of time, thanks to an incurable disease that is slowly killing him.
