Heretic Playing Cards by Lorenzo Gaggiotti (Stockholm17) is based on alchemy and the hermetic world. Salt (for the Jacks), Sulfur (for the Queens) and Mercury (for the Kings) are the three basic ingredients of the alchemist. This PCDB entry is for the Noctis version of the Gran Riserva edition, Sulfur class (just X serialized decks made with this class seal). Each deck in each class for the Gran Riserva editions have a custom printed seal for each class, plus a wax seal and signed by the artist. Other classes available in the Gran Riserva edition were classes for Sulfur, Salt and Antimony (for both Lux and Noctis), each with different quantities made. These are the tuck and cards as the basic versions of Lux and Noctis, but with the added seals and signed. In addition, there was also the basic versions of both the Lux and Noctis decks, plus uncuts of each. https://www.kickstarter.com/projects/requiemcards/heretic-playing-cards
