Double Proficiency
Double Proficiency is a two-person operation of Anna Urbanek and Jakub Wisz: a pair of writers and graphic designers working on a variety of tabletop RPG projects: mostly Herbalist's Primer (a system-agnostic book on magical real-world plants) and Project Aphelion (a hard sci-fi RPG with modular mechanics and choose-your-own-adventure character creation).
