The Castellan of North America is a self-declared caretaker of the continent. Not above interfering with national politics he rarely does so, content to keep the continental landmass free from what he perceives as threats to its stability and safety.
He has officially banned the Nagenti and Vampiri from setting foot (or tail) onto North American soil. While no countries on the continent have ratified his statement they unofficially support it. He however welcomes the Angelus and Draconus people to make there home there. Some countries are less supportive of this statement.
While holding no official title the Castellan posses a great deal of power due to his connections throughout all of North American as well as employing a large set mercenaries. It’s rumored that the Castellan was a military engineer or is secretly supported by the military because many of his mercenaries use military technology that is more advanced that found on modern North American soldiers.
