Inferno is a timeline that will be constructed by the community. In other words, a collaborative scenario.
300 years after the first, and last, global nuclear exchange.

The contributing factors to the last Great War are corrupted into myth and legend, with each culture detailing a separate story. Many communities have their own version of the events that transpired, but all have the same detail, that the world was covered in an inferno, set forth by the things that fell out of the sky.
