This map is meant to be for a section of the Nepenthe River, though it also serves well as any generic underground river. I had a larger battle in mind than would be accommodated well by other underground river maps I was finding online, so I opted to make my own.
I'm currently running Hoard of the Dragon Queen for 5e, and I've utilized Dragonspear Castle (which this river runs beneath) for a side quest while the party makes its way north along the Trade Way. I've also made custom maps for Dragonspear Castle's basement and warrens, though those will likely need some work before sharing them online publicly (if I ever do).

Map is 100px grid, and is 50x18.
