The hills just north of Bongolar are the home to several tiny bands of unaffiliated groups of humanoid monsters. Goblins, kobolds, and bugbears all struggle against one another looking to take the area's resources for themselves. They make a living trading prisoners and meats with the defenders of Petestone Keep. With more time, these groups could become a real threat to the peaceful peoples of Tramphollow.

The tribes of the Nasty Hills are:

• The Big Choppaz
• The Ded Hed Krew
• The Rude Boyz
• Skankvomit Clan
• Smrtboyz Clan
