The Citadel of the Rat King perches atop the black cliffs of Vermire, home to a collection of thieves, cut-throats and pirates. Though a relatively small principality, its reach is long since the Wererats work for King Leopold as his eyes and ears in far-flung courts. Allied to Westland via the Lion, the city is reachable only by sea or via the ancient road known as Grimm's Lane, which cuts through the Badlands as it heads north. 'Rat King' is the collective name of the five Wererat brothers who jointly rule Vermire with cruel fists. Each is equally corrupt and loathsome.
