From publisher blurb:
Diamond in the Rough is an adventure that has a group of PCs picking up a job for Dwarves of the Shieldcraft Clans in the West Keldon Mountains. It seems that a group of humanoids has pulled off a daring raid to the formerly secure vault and obtained a rather expensive gem. To recover this item the PCs will first have to reach the Dwarves, cross the valley and search the East Keldon Mountain range for these troublesome thieves. Of course finding the group of problems may prove a bit tougher than expected!
This adventure setting was designed for 1st/2nd Edition AD&D for the Filbar Campaign for a group of mid-level adventurers and DM. This adventure is easily adaptable to most any game and system. Save yourself some time and utilize it for a one shot adventure or a continuing campaign!
