NOTE TO NEW READERS: I've completed the full rewrite of this story, but if you wish to see the original story as well it will remain below the revised chapter entries. Because several chapters were expounded on or compressed together there's unfortunately no real corresponding order between where events appear in the "Revised" and "Original" chapters.
NOTE TO RETURNING READERS: This rewrite was more than skin deep. While core events will largely remain the same, the plot's events may still unfold in drastically different ways in terms of scenes and details from what you previously experienced. Hopefully the new interpretation of events will be an improvement in your eyes.
Our narrator has seen the darker side of life; abandoned, homeless, and finally chosen by a think-tank to serve in an experiment against his will. In their attempt to teleport him across continents, he was instead dumped into the Void between universes, where his only chance to exist again was to reach for the light.
By chance or purpose, he later finds himself in a world strangely similar to the one he had always known, but is yet completely alien; a world populated by many colored horses who can speak, think, fly, and even do magic. This is the story of that man. This is an adventure that was never supposed to happen. This is A Journey Unthought Of: A human's life in Equestria.
NOTE: This story has been marked 'Crossover' because the Earth the protagonist comes from is the one in the Doctor Who universe. The Doctor will also make appearances in later chapters.
If this story holds your interest, I've written four appendices and a now completed sequel, all of which you can find here. These stories enhance past events of My Little Pony: Friendship is Magic, though some of them may have been made partially obsolete by later episodes.
