The Anomalous Figure

Twilight and David finished the book about humans with 10 volumes and soon it was published and mass produced soon everpony knew about humans and their cultures and histories. David got a custom to living in Equestria and got use to its vocabulary and how everyone was a vegetarian like Princess Celestia had requested he never told anyone about the lab and he stayed away from the Everfree Forest mainly do to the fact that he knew what was in it. Sometimes he would get summoned at the Canterlot Castle and he would ride a train there but every time he went he got blood drawn to make sure he was healthy it was always in that laboratory and the doctor ever time would come back and tell him healthy as usually and he would always get injected and waken in his house that he bought with the bits he made for helping Twilight write the book. But David found himself wondering what was it like on Earth was everyone dead or did they find a cure? But sadly he will never know.
