RiverClan's main source of prey and protection, but it is as changeable as the moon. Sometimes it is quiet, gentle, and murmuring; but other it froths and roars like a Twoleg monster. Even RiverClan's best swimmer should be wary of the river whenever it's water rises.
The river runs from down inside the gorge at the WindClan border, drops at the falls, drifts under a twoleg bridge and then levels out at the ThunderClan border.
