Gruesome Gangs is an exciting Pathfinder Roleplaying Game® compatible product line providing the Game Master with a collection of non-player characters (NPCs) designed to work together from the perspective of backstory, game mechanics, or both. The groups are presented at different Challenge Ratings to increase their utility for multiple gamers. In addition, this allows player characters (PCs) to encounter one of these groups early in a campaign and then again after both teams have gained experience with minimal extra work for the Game Master!
If the entire team is unsuitable for inclusion in the campaign at the time, then NPC stat blocks can be used individually as needed. A mixed approach can also be interesting. By introducing a single foe into the campaign, this product gives a number of friends or allies that foe could call upon after running afoul of the PCs! This gives the Game Master a ready-made answer to who would the NPC go to for assistance, or even who would come to avenge his death at the hands of the PC party!
