RPG Geek - Mountains of Madness

From the prelude:

The barkeep, Sama, has been busily serving patrons this fine fall day. The harvest festival is nearly upon the town and the locals are getting in their last cozy visits to their favorite watering hole before tourists flourish here and take the place over for a week. You’ve already been mistaken for a harvestgoer by more than a few locals. You look around and see a few friendly faces among the crowd. Perhaps one of them would make a fine adventuring partner on your journey. Then again, it may be best to go this alone. That choice remains yours. In the meantime, one well-dressed halfling patron, who may have had more than his share of ale, comes up to you and offers to play a simple game for a wager.
