Canterlot, the last equine city, is an atmosphere-piercing metropolis of vast size. Clinging to its skin are the zones, a series of semi-autonomous city-states, each of which enjoys a different - and rigidly enforced - level of technology. Ponyville is pre-industrial; in Neon Heights they have television and electric trains . . .
Following an infiltration mission that went tragically wrong, Twilight Sparkle has been living incognito, working as a pathologist in the district morgue. She's never caused any bother for anyone, and she's certainly never caused any bother for herself. But when a near-dead alicorn named Shining Armour drops onto her dissection table, Twilight's world is wrenched apart once more as her past finally catches up with her, for Shining Armour is a winged post-equine from Canterlot's Celestial Levels, the penultimate heights of the Godscraper.
If Twilight is to save her life, she must leave her home and journey into the cold and hostile lands beyond Canterlot's base, starting an exile that will take her further than she could ever imagine with only her saddlebag of medicines, and the foul mouthed pegasus Rainbow Dash, to rely on. However, things aren't always that simple, and even as Twilight flees for her own safety, she soon finds herself entangled in a fight for the survival of the Godscrapers very exsistence.
