Hostile Biosphere
Description The world is teeming with life, and it hates humans. Perhaps the life is xenoallergenic, forcing filter masks and tailored antiallergens for survival. It could be the native predators are huge and fearless, or the toxic flora ruthlessly outcompetes earth crops.
Enemies Local fauna, Nature cultist, Native aliens, Callous labor overseer
Friends Xenobiologist, Tourist on safari, Grizzled local guide
Complications  Filter masks fail, Parasitic alien infestation, Crop greenhouses lose bio-integrity
Things Valuable native biological extract, Abandoned colony vault, Remains of an unsuccessful expedition
Places Deceptively peaceful glade, Steaming polychrome jungle, Nightfall when surrounded by Things
Seismic Instability
Description The local land masses are remarkably unstable, and regular earthquakes rack the surface. Local construction is either advanced enough to sway and move with the vibrations or primitive enough that it is easily rebuilt. Severe volcanic activity may be part of the instability.
Enemies Earthquake cultist, Hermit seismologist, Burrowing native life form, Earthquake-inducing saboteur
Friends Experimental construction firm owner, Adventurous volcanologist, Geothermal prospector
Complications  The earthquakes are caused by malfunctioning pretech terraformers, They’re caused by alien technology, They’re restrained by alien technology that is being plundered by offworlders, The earthquakes are used to generate enormous amounts of energy.
Things Earthquake generator, Earthquake suppressor, Mineral formed at the core of the world, Earthquake-proof building schematics
Places Volcanic caldera, Village during an earthquake, Mud slide, Earthquake opening superheated steam fissures
