Principium Paradoxi started off a plain old setting for a series of Vampire: The Masquerade but it has grown to a full blown world to run a number of World of Darkness Chronicles which include a Mage: The Ascension to potential crossover Chronicles.
It will look familiar to anyone who has played any tabletop role-playing games based in the World of Darkness but there are few subtle differences which will be personal twists added by myself to suit my style of play and personal tastes.
The world itself is based on a darker version of our modern world in which exist Mages,Vampires and other supernatural beings live in the shadows on the edge of human society. From the shadows some of these supernatural beings both guide and influence the mundane world around them either for their own ends or in attempt to improve the lot of humanity itself.
Principium Paradoxi is set on Earth starting around 2020 CE in a world which has one major difference to our own in so much the spectre of COVID 19 never appeared. Though this does not mean the world is a safer place because of the supernatural beings in the background.
