Big thanks to Hei201 to providing me with cover art, and for being the only one who was willing to help me out!

When a man from a different world accidentally falls into a portal that lands him in Equestria and is now lost and now parts of his memory are locked. He's a highly-trained soldier from his world so his absence will be noticed. Can he make sure that he makes it back to prevent a possible invasion? Or will he come back to invade this new land? What choices shall he make? Will he establish peaceful relations and start trade? He has no idea. And the things he will experience shall change him forever, for better or worse. But before he can do any of that, Fluttershy is responsible for taking care of him first.

After reading other pieces I think I'm finally ready to begin writing myself I'm being held at gunpoint because I lost a bet. Feedback in all its forms is appreciated. One note however: I just hope I didn't create a Mary Sue/Gary Stu or otherwise I'll be very disappointed in myself.
Another note: Just because this is my first story, does not mean I get a free pass. So go crazy with the comments, I guess.
This is also a very bad story, in my opinion.
