The Canterlot Reformation, Reintegration, and Parole Office. Where supervillains, other-dimensional monstrosities, and general ne'er-do-wells are sent to become better people and reintegrated into society after their encounters with the Elements of Harmony. Some are just there for the therapy.

Unfortunately, its staff includes five mares who are a hair's breadth away from turning evil themselves. If they could be bothered to give a damn.

Somepony's gonna lose their job.
