Strongholds
A system-neutral guide to designing fantasy strongholds across technological eras from the Stone Age to the Renaissance. It explains why fortifications are built, examines historic and fantastical materials, and discusses practical layouts, local communities, and the story possibilities of a stronghold’s location. Standardized room guidelines help establish a basic plan, while free-form advice supports customized designs for individual campaigns.
