From the game introduction:
The idea for Pars Fortuna
™ hit me one night when I was suffering from a slight fever. I had recently posted a few monsters on my blog that were generated using some wonderful random generators found online. The generators spit out a concept, and I fleshed the concept out and gave it statistics. While I was lying in bed, temperature around 100‐degrees, a thought occurred to me – What would it look like if you threw out all the usual tropes of fantasy games, the dwarves and elves, fighting‐men and magic‐users, dragons and giants, etc ‐ and randomly generated replacements for them. What kind of world would you get?
A few months and many hours of writing later, this book is the answer to that question. Over its development, Pars Fortuna™ became a bit more than just a randomized role‐playing game. I also tried to make it a toolbox of interesting rule variants, with a new spell system, different ways to looks at weapons, and a few other tweaks that veteran Referees and players will, I hope, find useful. For new and old players, Pars Fortuna™ is a self‐contained game with a mini‐setting that can be played “out of the box”, so to speak. For veterans, it can also serve as a place to grab new monsters, races, spells, magic items and rules to liven up an old campaign.
