The Five Mystical Substances
The Five Mystical Substances are as follows:
Mystical Substance (Corresponding 'drug') Corresponding Moon Corresponding Element
Aer (Psychedelics) Aero Aer (Air)
Eth (Speed) Eth Ether
Flam (Opiods) Flam Flam (Fire)
Kaf (Tea/Coffee aka 'kaf') Hydro Hydro (Water)
Terra (Cannabis) Terra Terra (Earth)
Each Mystical Substance (aka 'drug') directly corresponds to one of Five Moons (Hydro, Terra, Eth, Flam, Aero). Each drugs' effects are potentiated or diminished by the phases of its corresponding Moon. Each drug temporarily conveys certain effects; conversely, regular use of any one causes adverse reactions. Each drug/moon also corresponds to one of the Five Elements: Hydro (Water), Terra (Earth), Ether, Flam (Fire), and Aer (Air)
Alcohol is virtually unknown, except perhaps in some niche chemistry/industrial applications.
Commonly consumed drugs include: Kaf (caffeine), Terra (cannabis), Eth (uppers), Flam (opiods), Aer (pyschedelics). Public social gathering halls typically, but not always, revolve around Kaf Parlo(u)rs. Combination Kaf Parlo(u)r/Inns are ubiquitous, in much the same way tavern/inns exist in most fantasy realms.
