The origins of the dufferpeds are unclear; most commonly they are believed to be a clan of dwarves cursed by a powerful sorcerer many years ago. Appearance-wise they seem to be normal dwarves from their heads to their waist, but at the waist is when things get strange: a single central leg ends in an enormous foot, and the dufferped moves by making long hops, allowing it to proceed at a surprising speed.

Dufferpeds are of foul temperament, frequently cursing, and constantly bemoaning their unique condition. However, they are courageous and capable warriors, wearing heavy chain mail and bearing long spears and shields into combat. Dufferpeds are also excellent miners, highly-skilled fishermen, and boatmen as they are able to use their enormous foot as a canoe.
