By the year 2021 it has become obvious that there are still many ponies left on earth. More than had originally been anticipated. As well, humans around the USA. and the world, have continued to change, even after the fall of Discord. Due to the special nature of these people, the US Government created a new branch of law enforcement.
The Pony Special Investigation Division's job is to investigate crimes by and against ponies in the USA, as well as responding to crimes against US Military and Civilians world wide. Dedicated to finding the truth, the agents of the PSID operate under the Homeland Security umbrella.
Ponies may have been left behind, but they are not forgotten. These are the case files of the PSID.
This is going to be a little different, any author that wants to put their own story in can communicate with me and be included.
