Building Worlds

As a Game Master, you control the details of the galaxy your players explore. While Starfinder offers a diverse assortment of worlds to experience, there are infinite possibilities for new planets, whether in the unexplored regions of the Vast or in entirely new campaign settings of your own creation. Building your own campaign world can be a deeply fulfilling creative process, as it lets you bring to life the exact setting you envision. It gives you great flexibility so you can build only as much as you need for the next few adventures, and you can adapt your setting on the fly to meet the demands of your story. It also gives you great control, allowing you to build precisely the setting you need for the story you want to tell. Finally, it bypasses some of the issues that can come with playing within an existing campaign setting, where you might create a narrative that contradicts published canon, or your players might stumble across major plot or setting spoilers. Whatever your world-building goals, this chapter guides you through the design process step by step.
