Gangs of Dunwall
The Hatters are a major gang in Dunwall. Once the most prominent syndicate in Dunwall, their forces were substantially weakened by the coming of the rat plague and the subsequent upturning of the city's criminal underworld. After losing the Dunwall Whiskey Distillery to the Bottle Street gang, Slaughterhouse Row to the Butchers, and the Wrenhaven River to the Dead Eels, the Hatters have resorted to inciting gang warfare to recover their territory.
The Hatters are easily recognized by their top hats. Their base of operations is in Drapers Ward - specifically in the local textile mill - alongside that of the Dead Eels.
The Hatters are headed by the Geezer, an elderly man kept alive via experimental life support machines.
