I'm Making my Own Adventure

If you are looking to create your own Starfinder adventures, Chapter 2 provides you design guidance ranging from the broad strokes of building an entire campaign, to writing individual adventures, to the particular considerations of creating an encounter. This chapter also provides a toolbox you can use to build the creatures, hazards, items, and other elements you want to use in your adventures.

If you plan to create your own setting, the world-building section of Chapter 2 can guide that process and help you establish the details you'll need to bring your galaxy to life. You can also use the information in Chapter 3 to detail those parts of your galaxy.
