Campaign Hexagon System Judges Guild Dungeons & Dragons

Campaign Hexagon System, published in the late 1970s, provides a flexible, numbered hex‑map framework for wilderness exploration in early Dungeons & Dragons. Designed for referees building large, open‑world campaigns, it standardizes terrain mapping, encounter placement, and travel tracking. Its modular sheets support expansive, customizable settings, making it a foundational tool for classic hex‑crawl play and one of Judges Guild’s most enduring utility products.
