Brimm torture wagons
The torture wagons used by Brimm are a method of sentencing the worst criminals to death. Each wagon is under the control of a Brimm Judge, and is protected by mercenaries which are contracted to the city.
Torture wagons start a journey with four convicts who have their limbs broken and intertwined with the spokes of the wagon wheels. Usually one of the mercenaries carries a hammer for this job. This causes a slow and painful (and often loud) death, upon which the person is discarded and replaced by one of the tied up prisoners the wagon also carries.
The wagons purpose is to discourage crime, and they are a very good deterrent. Usually these only wander the territory of Brimm, but recently Lord Trebius Hakar has ordered them to travel down and potentially discourage some of the banditry going on near Lennox.
