Publisher blurb: The underbelly of the city is riddled with dark crawlways and treacherous passages. The locals call this foul network the Ratfang Sewer. Filth and grime abound in these damp tunnels and all manner of disgusting creatures slink about, plotting, scheming and performing vile acts to appease dark powers. This map shows a network of passageways and foul canals, detritus and trash litter the floors of side tunnels and antechambers. Gates and grates divide sections of the network and protect one large chamber that has been re-purposed as the lair of a wicked denizen.
