Knights of the Round Tabletop

Publisher's blurb: A group of three knights sit at a table in the far corner of a tavern. On the table are a large piece of parchment with simple shapes drawn on it, a satchel with a strange seal on it, multiple sheets of paper, wooden dice and wooden figures. If the PCs approach the knights, they’ll ask if the group would like to join them. They introduce themselves as Geone, Leo and Arkan. They are starting a fresh game of Fire and Brimstone.
