This fiendishly forbidden book and tarot card deck draw upon Le Dictionnaire Infernal (Infernal Dictionary), a legendary tome originally published in 1818 by French occultist Jacques Auguste Simon Collin. Working from centuries of arcane magical texts, Collin described ancient daemons and organized them into hellish hierarchies. Now Ariana Osborne has reinterpreted Collins classic text for todays audience and created a divination system to identify the unique strengths and specialties of 69 of those daemons and explain how to summon their energies.
