An ever-shifting tropical wilderness where mangrove coasts and flooded grasslands meet a surreal water-carved landscape of karst towers, sinkholes, and thousands of streams that vanish into giant cave systems as quickly as they appear. Here, mercenaries of the Wisterian Company venture into forgotten ruins in search of gold and glory, reptilian clans of natural-born predators stalk the waterways, and the so-called Ghost Men strike out from hiding on mysterious missions before disappearing into the karst like a mist.
