This is a story about a tabletop role-playing campaign played by a group of people who know each other. After playing many campaigns together, one player suddenly said, "Why not turn it into a shared universe? So many of our characters' stories are connected, after all."
I think that's a bit much for me to handle. Your roleplaying is so terrible that the characters' actions would make no sense unless I heavily rewrote them. Still, it sounds pretty interesting, and adapting existing material should be easier. At least I won't have to rack my brain trying to come up with a plot.
So, with the help of several game masters and more than a dozen players, the foundations were laid for this strange book: a record of our tabletop campaigns.
