The Sector Construction Guide jumpstarts creativity to develop sectors of the referee’s own making, with a focus on the Foreven sector, an area adjacent to the Spinward Marches. The guidelines in this set provide tools to develop a detailed sector, whether in Charted Space or in an entirely different universe, covering overall setting creation, mainworlds, polities, and alien sophonts, with suggestions for variants to system creation rules to fit a referee’s unique ideas.
