The human tumbled and fell back into the river and rose only in time to see the rapidly approaching wall. He held his arms helplessly before his face as the speed picked up even further. Then all was black. The human was sucked beneath the waters and found himself tumbling in darkness. The river went through an underground pass, taking him with it. He hit his head off of solid rock several times, and his head swam as his lungs burned desperately for air. The last thing he saw before blacking out was a faint light in the distance.
