It is a one shot, Pathfinder Society scenario. This scenario requires 1st level characters and is designed as an introduction into the Pathfinder Society. The Pathfinder Society has more structured play, and stricter rules enforcement than home games, but we have a lot of fun, and the modules take about 4 to 5 hours to complete. Afterward the event gets reported to the Society and each player gets a Chronicle sheet detailing what treasure is available to the character. How much prestige, gold, and XP were gained. With society, normally each session is 1 XP, when your character gains 3 XP you raise a level. It doesn't take long to setup a character. Registration with the Society on the paizo.com IS required. There are also pre-generated characters for each level, available on the site. The Pathfinder Society is an excellent way to find a game at random days times, and games are often going on at odd hours, like the middle of the night. If you are interested, please give us a try. We don't bite, and we have a lot of fun.
