Astrum Arentum

This group is a splinter from MacGregor Mather's Coven, the Golden Dawn. Established by none other that Aleister Crowley in 1905 to further his research into the darker side of magic (This is before he established the Illuminati a few years later). These guys have been incredibly difficult to infiltrate as members only know their immediate superior and the people they recruit. The organization has continued after Crowley’s death and is devoted to recovering and controlling all arcane items and books to further their own powers over the Earth.
FIELD ADVICE: Make sure you bring heavy warding spells to any play date you make with the Astrum Arentum, these bastards don't pull their punches when it comes to protecting their secrets (you can ask Esme about that.)
