The sun has died and in its death scared the earth into a wasteland. There are very few still fertile places, and those places are heavily guarded. Each fertile is lit by an artifical sun (there are only four). People are safe within the light, but once they step into the dark, they are subject to the elements. The wasteland is home to creatures only dreamed of. The most dangerous, Shadows. Shadows are vile creatures that cling on to an idividual and will eat their host inside out thus creating another Shadow.
Many travelers carry a form of light to kill a Shadow, but even a small light source can prove useful. Shadows leark everywhere there's darkness.
Other creatures include the normal night dwellers- bats, wolves, snakes...ect
