Providence - Main Rulebook
Providence is a hollow world meant to serve as a prison for those who rebelled against a stratified and unjust society. They fought under the banners of Gods who turned out to be merely powerful mortals and were defeated along with their false deities. Soon after their interment into a number of prison-camps¸ the gates that deposited them to Providence stopped working¸ trapping guards and prisoners alike. After a number of bloody rebellions (and a few generations)¸ the prison system broke down and most of the cities were freed. Most of the world is unexplored jungle¸ containing odd creatures that were once like the PC races. And it's a world that appears to be coming to end as cataclysmic natural disasters begin to tear it apart. Countless roleplaying scenarios are hinted at¸ but little support is given to realize them¸ though.
