After a magical accident, a human baby ends up in Equestria. When they figure out that the mysterious creature is from another technologically advanced world, research and experiments begin on the subject. Where is it from? What lies beyond Equestria, beyond Equus? What other worlds are out there? What kind of physics is there left to learn? Can they ever return it to its home world? Follow the baby's life as it grows up and what the Equestrians learn from it.
Warning: lots of math and science!
