Organizations, Agencies and Secret Societies
This supplement describes nearly 50 government agencies, secret societies, political movements, and resistance groups from the early 20th century. Entries cover each group’s purpose, goals, practices, and membership; society profiles also note their founding date, regions, and symbols. Designed for early 20th-century role-playing campaigns, the material can be used with different settings and rules systems. It provides background and plot possibilities rather than new game mechanics.
