Historia Regum Britannia

Historia Regum Britannia (also know as De Gestis Britonum or the First-Class Singularity) is the adoptive son of Princess Luna, former second prince of Canterlot and the King of Britannica. Considered a singularity by higher forces ad that of Scheherazade.

Historia was born to two British nomads who traverse Great Britain. However, at some point, he was transported to Equestria with Christopher Sol being with him. Found by Princess Celestia, he was taken in by Princess Luna after she was freed from the Darkness, becoming her adoptive son.
