Whether your heroes are racing down the river in pursuit of villains or investigating rumors of aquatic monsters, there's no need to sketch every rill and eddy. This Pathfinder Map Pack provides stunningly illustrated 5" × 8" map tiles that can be positioned to form a variety of modular, customizable river configurations. Game Masters shouldn't waste their time drawing maps every time adventurers ford a river or board a boat. With Pathfinder Map Pack: River System, you'll always be ready to brave the rapids!
