|Dourhands is a concept which has only appeared in an adaptation of the works of J.R.R. Tolkien.|
Some time during the Third Age, the Dourhands were experiencing great poverty and hunger. Under the leadership of Skorgrím they raided the Elven refuge of Edhelion for their relics and treasures. He also had the Dourhands ally themselves with the goblins and trolls to drive out the Elves. Yet, it was not enough and he was slain in battle. Leaderless, the remaining Dourhands scattered themselves throughout Eriador setting up strongholds and camps.
Six hundred years later, shortly before the War of the Ring, a Gaunt-lord from the the First Age named Ivar who dwells in Garth Agarwen, an ancient fortress of Rhudaur, summoned a fell spirit to possess the preserved corpse of Skorgrím. The wight convinced the Dourhand that he was a dwarf from the line of Skorgrím and managed to ally them with the forces of Angmar.
Likely based on the 'wicked dwarves' mentioned in The Hobbit who sided with goblins.
