The narrow plain and foothills between Fangwood and the eastern slopes of the Mindspin Mountains are home to an unusual water feature of unknown origin or cause. Sprays of water not unlike miniature geysers leap up one after another in a slow-moving progression that winds its way throughout a region of roughly 30 square miles.

The springs erupt from one of the countless narrow vents that lace the region. Creatures of elemental water are unusually common in the shallow lakes and tarns here, giving support to theories that tiny portals to the Plane of Water riddle a network of water-filled caverns below the region. No sizable entrance to these rumored caverns has yet been found, despite several attempts by curious scholars to do just that – especially since the region’s relatively remote location and the large number of oozes and water elementals that prowl the region make expeditions to the Marching Springs a costly affair.
