Adverse Weather and Terrain

Difficult terrain can slow progress during overland journeys but rarely lasts long enough to impact interstellar voyages. Unless it's important how far the group gets in a particular time frame, this can be covered with a quick description of chopping through the vines, trudging through a bog, or piloting through prolonged turbulence or a Drift storm. If the characters are on a deadline, adjust their speed on the Travel Speed table (Travel), typically by cutting it in half if almost all the land is difficult terrain or to one-third for greater difficult terrain.

Hazardous terrain, such as the caldera of an active volcano, might physically harm the PCs or their vehicles. The group might have the option to travel directly through or to go around by spending more time. You can transition into a more detailed scene while the characters move through hazardous terrain and attempt to mitigate the damage with spells or skill checks. If they endure hazardous terrain, consider giving the PCs a minor or moderate XP reward at the end of their exploration, with slightly more XP if they took smart precautions to avoid damage.

Dangerous crevasses, quicksand, and similar dangers are environmental hazards. Hazards that affect a starship instead use the cinematic starship combat system.
