Ambrosian tobacco was a psychoactive type of tobacco that could be smoked, inhaled, or chewed. From an unknown planet of origin, Ambrosian tobacco was first utilized by the nomadic religious order called the Whills. Its use spread to other mystical organizations including the Je'daii Order and the Temple of Iziaka. Ambrosian tobacco was often rolled into a special kind of cigarette called a “cret”. Meaithe Akam often used crets to aid in her communicative efforts with the Otherworld and as a general sedative.
