During excavations in the deserts of equestria, Princess Celestia and Twilight stumble upon knowledge of ancient beings, including a book that allows the users to travel through the universe, if powerful enough. The first trip performed by the Princesses Celestia and Luna don't end well, meddling in a war on a far away planet and calling attention to their own planet. Shortly after their return, equestria is attacked by several hordes of strange and brutal creatures. Not having the slightest chance they call upon another spell, summoning "the one", namely Sam "Serious" Stone. Will he be able to stop the invasion of the pony world from his archnemesis Mental and free the universe once and for all?

The Highschooler Simon has a tough live and slowly loses his will to live. He is all on his own, until one night he is accidently pulled to equestria...without memorys but now equipped with untapped powers. Will he learn to control it and find a way back?

While trying to find back his memorys he builds up close relationships to his new friends in ponyville, but not everything works out fine and problems arise.
