Publisher Blurb: The roar of a river's white waters can fill an adventurer's heart with hope of escaping pursuit or dread at facing an insurmountable obstacle. 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. Inside, you'll find 18 richly crafted map tiles, including: Fallen Tree, Sandy Banks, Flood-Swollen Waters, Tributary Confluence, Stony Crossing, Exposed Riverbed, Meandering Bend, Cut Bank, and Rocky Rapids. 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! Suitable for experienced GMs and novices alike, this product fits perfectly into any Game Master's arsenal. Wet, dry, and permanent markers erase from the tiles! With revised packaging that includes a reusable box for easy storage, Map Packs have never been so useful!
