Check out the final preview for the Strange New World Gazetteer: Volume 1.
Damps (from the Middle Low German word dampf, meaning "vapour") are heavy gases that can be weaponized. Found throughout the New World in such frequency that adventurers have begun using them in the fight against the beasts and horrors of the strange frontier. Damps are gathered from various sources where they might form naturally or even supernaturally. They are mostly invisible and may be found in enclosed environments such as basements, sewers, wells, tunnels and ships' holds. Or extracted from gaseous veins and volatile vapor pockets inside caves and mines. Perhaps one of the greatest sources of damp vapours are the perilous black swamps where toxic marsh gases linger.
