The river serves as a boundary between ThunderClan and RiverClan territories, and also between the RiverClan and WindClan territories, where it flows through a very steep gorge. Fat, brown bulrush heads and dense reed forests are said to jut out of the river, along the bank.The river is said to be huge, as big as the ThunderClan forest camp. In greenleaf, Twolegs bring their boats, and their kits frighten all the fish while they swim, making it harder for RiverClan to feed themselves. It is a source of prey and protection to the RiverClan cats, seeing as it is close to their camp
