We have a sacred duty. Hope nobody gets in our way.
An old branch of the Anglican Church, the Sacred Order of the Knights of Saint George can be found in all sorts of places. On the front of things, they are a humble order of Christians, dedicated to charities and good works. But, in secret, they have a darker nature; the core of the Sacred Order, the true Knights, are monster-hunters, motivated to hunt Witches and all spawn of magic because they know of the existence of dread and powerful entities. These "Faceless Angels" slumber, now, but magic makes them stir, and were they to wake, then the world would be destroyed.
Through mystical rites known as the Goetic Gospels, the Knights draw upon the powers of the Faceless Angels and use them to oppose all beings of magic.
