Everything you need to invent somewhere that isn't Earth: the planet, who lives there, the ship you arrived on, the gadget in your pocket, the dystopia you fled, and the moment the neighbors finally called.

These are the science fiction counterpart to the site's fantasy set, and they're built to be combined rather than used alone -- a world type, a biome, a species, a civilization and a hazard is enough to run a session or start a chapter, which is exactly what the Alien World preset stacks into one press. The hard-science material and the invented material are kept in separate filter categories throughout, so you can stay inside real exoplanet classes and plausible biochemistry if that's the story you're telling, or turn the filters off and take the ringworlds and the precursor ruins as well. Note that this group is deliberately separate from Space & Astronomy: everything there is a real catalogued object, and everything here is fiction.
