Albion is the magical dimension that lives on top of the Mortal Plane, lying parallel to our own. Within this realm exists all sorts of fantastical magic and mythological beasts -- from the familiar dragon to the strange Nimiskal. To receive the Mark of Albion in the Mortal Plane means you have been chosen to become a Sorcerer and learn the secrets of Albion, and even bring those secrets to the outside world.
Sometimes, the Mark shows itself on those of ancient sorcerer bloodlines. Other times, the Mark appears on a random lost soul.
However, some are jealous of those who have been chosen. By the rules of Albion, only those who receive the Mark may practice magic. Some cry out against these laws and practice magic anyway. These are the followers of the Black Fox.
