Someone on the facebook group told me there was a PDF version online somewhere but, since they already had it in printed form they didn’t have it. I went looking for that PDF, spent some time on it but I didn’t find anything.
I bought the first Campaign Book in digital format, and I think it’s only a matter of time before they make the second volume available for purchase. You can send the PDF to a printing company and have it come out something like this.
If you really want the original printed one, you can find copies on Board Game Geek, but be prepared to spend a large sum of money.
