My name is Jace. It has been 20 years since the portal to Equestria and Earth has opened. When I was young I did something terrible after that I was taken in by a good man and his daughter. I am now 16 years old and going to Canterlot high with the very same girl who helped me and now it's time to survive at school in the day but to live at night. I am a vigilante who helps stop crime whether minor or large I will stop it. By day Jace and by night the black guardian.

It's not set in the Equestria girls universe or the canon universe
