Rifting off the
Madnesss Dossier again, this time blending it with
THS.
There were other histories, a nuclear war, one where the Nazis won, one where the old kings never fell and joined their crowns with the church and the corporations, worlds where things simply withered and collapse, sometimes from climate change, sometimes form simple despair. Poison hellwords that want to come back.
The chance of these worlds returning involves Pragmaclasts. Items left over from other world paths and futures lost. The agency has one job, to find and destroy pragmaclasts. Beware, a certain type of person, someone who hates the world and loves the hell the pragmaclast is linked to will fight to get enough pragmaclasts together to crack reality. Neo-Nazis still fighting for the Fuhrer, would be masters of the universe, fools hungry to be barbarian warlords, and idiots who think they are of the lineage of Christ and the True
Merovingians. You must in secret fight these mad fools and their dark cults of nihilism and slavery.
These alternate realities aren't as real as our world, they need to leach off our reality. Each pragmaclast allows a little of our world to be bled away. If more than a few pragmaclasts are gathered together then reality quakes can bring people and things from other realities to our own. Some of these know how to pop our reality like a soap bubble.
