It was during Harry's summer before his second year. He was locked up in his room and unable to leave with out the grace of his neglectful relatives. In desperation to escape, his magic came to the fore and whisked him away to a new world. A world with no Voldemort, no fickle wizard society, and no Dursleys.
In this new place, with a new body and a chance to be something, someone else, to choose his path, he seizes it.
Not that he is without secrets in this new world. In the middle of slowly building relationships with other ponies, finding himself, and reaching his own chosen destiny, he tries to keep secret his origins, his true abilities, and one rather obvious difference between himself and other ponies, something that could disrupt his new ideal life in this amazing world full of ponies.
