The Ilithiia River (pronounced ill-ih-THEE-ah) is a river in northern Yurukan. It begins in the foothills of the Northern Wall, where its many small tributary streams collect before flowing into Lake Ilithiia to the south. As with the lake, many in Yurukan believe the waters of the river to hold curative properties. Some even claim the ultimate source of the river, a spring which they say has yet to be located, can reverse aging.
