Paizo has just released a new adventure module for Pathfinder. In Hell's Bright Shadow is the first in the 6-series Hell's Rebels adventure path (I wonder if they know The Devil's Rejects). Do your characters have a better chance than a snowball?
This first module is designed for 1st level characters. It comes with a double-sized gazetteer of the city of Kintargo (where the adventure takes place, stats for a plague doctor from Khari (an NPC the characters will interact with... and hopefully not just stab in the face like some adventuring parties I know...), and a collection of monsters (both good and bad) to more-than-likely slay or collect in some fashion.
