On Her Majesty's Arcane Service

Her Majesty Elizabeth, Queen of England, secretly established in 1560, the second year of her reign, the Arcane Service. The Service is composed of people, usually but not solely of magical bent, who have sworn to protect the realm from magical assault. The player characters are assumed to be agents of Doctor Dee. They are people passionately devoted to the welfare of England, and of the Queen, and unafraid of dealing with magical creatures and powerful workers of magic. At times they may be performing political missions, perhaps in other lands, perhaps in England. At other times they will be defending the realm from magical assault from foes domestic and foreign. They can function as spies, as diplomats, as magical assault squads, and as investigators.
