Humans in Equestria. It's almost a chiche, really, but humans aren't the only beings that end up there. Sometimes they come from farther away than Earth. Not just in space, but also in time. What happens when a being nopony knows anything about accidentally comes in, and tells what he's seen and done? Confusion, and eventually understanding. One may hope.
A parallel story to Beauty Is Where You Find It, set between Nathan Traveler's Omnius' Travels: Equestria and Eternal Twilight.
