A border exists from a result of a uneasy truce between humans and pony kind in Equestria. Over 100 years have nearly completely cut of the cultures of the two. Dr. Moss, who studies humans from history and what he can glean from the border, is threatened to have his funding removed to teach his subject at Canterlot university because of the lack of interest. He resolves to make a dangerous crossing into the human land to see what has changed since the war.
