Astronaut Marcus Andrew Underwood was just thrown into the abyss of space, and even worse, his ship has just crashed into a planet known as Equestria. There are no humans, only a population of ponies, who seem to find him hostile. Marcus tells himself he won't break under all of the stress. But maybe he can be used for something. Maybe Marcus crashing here can help Celestia and the whole of ponyville.
Huge thanks to randaltherin for the editing.
