"The town of Ponyville doesn't exist."
That's how this all started. That single matter-of-fact sentence is how this entire thing began. Because despite what the books say, despite what the maps say, despite what the princesses say, Ponyville does exist.
Lyra remembers. Her memories of Ponyville run perpendicular to her memories of growing up in Canterlot. But of course nopony believes the crazy conspiracy mare.
That's fine. Lyra doesn't need anypony to believe her. She just needs to find her way home.
