When Kyle becomes a pawn in a disaster in his home town of Olean, he passes on due to this. He never knew he would wake up, but when he does he is somewhere he never even dreamed of, and something, well somepony is there with him. Now he has to find out if this is his new home, or if he is to leave immediately. Will he stay or go? And what other adventures await him in this magical land?

After falling asleep in a park you (Phil) recall from your childhood during a drunken wander, you find yourself amongst the land of Equestria; the land of ponies, peace, harmony, friendship and where the female to male ratio is 10:1 (and that's an understatement). You then spend your time finding out how you ended up in Equestria, all the while having fun, making friends, maybe even finding love finally. Oh, and who's to say you won't be a complete arsehole about the whole situation? However, with you and your sub conscience at your arsenal, who can really stop you from being one? A simple man in a magical land with pegasi, unicorns and earth bound ponies with the strength of a freight train, things will surely end up fine, right?

A second person story if you haven't realised by now.
