Mark Fénix, a thirty-four year old man, as well as a builder and an admirer of art,finds himself falling through the Canterlot Castle roof after simply trying to flop onto his bed at night...although the forces of nature had something to do with this transition between planes. He'll have to wait at the castle before he can return home, but will he WANT to return home? Especially with the wonders that this new world holds.

Apparently, the one who made that work of art is called Moe, but I can't really reach his page.
