Trivia & Notes

 * This page refers to Eurasian mythology, as such the Guardians that protect Albion may not actually be the Archangels, but may be intrepreted as such.
 * It should also be noted there's a chance the four archangels are actually based on the Guardians and never actually existed to begin with.
