d20 Apocalypse - Exit Mundi
The Fallout is the generic name given by the survivors of the ruined Earth to the strange effects that have taken over the planet. Over time, each generation of humans has blamed more and more on The Fallout, whether it was actually caused by these effects or not. It is suspected that The Fallout was either the cause of the devastation, or a result of it, but no one knows for sure.
Many times the effects of The Fallout are very obvious. Mutated creatures, plants, and even humans are very obviously twisted and misshapen by exposure to The Fallout. Even the land itself sometimes seems to be torn or shattered somehow, and a slightly glowing miasma hangs over it warning beasts and travelers alike of the dangers within. Other times, the danger is more subtle and not apparent it is already too late. The most subtle effect of The Fallout affects the mind – humans and animals can start to lose their minds, their intellects draining away until they are Savages. Savages of all kinds wander the land in dangerous bands, randomly moving from area to area, following a pattern only they can understand.
