From the publisher:
The naysayers were right...oil wells the world over have gone dry and civilization has collapsed into chaos. But from the ruins of war a new world is born. Magic is now humanity's ally as he seeks to rebuild that world that technology destroyed.
Afterpeak is a Systemless Setting designed for use with any role playing game. It combines aspects of Fantasy, Science Fiction, and the Post Apocalypse genres without being confined by the stereotypes of these styles of play. Afterpeak includes information on gaming in this new world, a new system of magic to integrate into your campaign, supplemental information for the MADS role playing game, and dozens of new monsters to throw at your players. Do you dare enter the World of Afterpeak?
