Arthur Green is the kind of person who prefers stargazing to saving worlds. So, of course, fate decided to throw him into a fragmented Equestria, where each of the Elements of Harmony has transformed the bearers into alicorns with more power than common sense. Oh, and they've forgotten who they are. Just the usual.

As if that weren't enough, the event that divided this world conveniently coincided with his arrival, making him the "special guest" to fix the mess. Now he must join forces with Twilight Sparkle, the only sane pony in this madness, to recover the missing pieces of the Elements and save Equestria... although really, Arthur just wants to save his own skin and get some sleep.
