Greatriver is the most prominent river of southern Hallearia. It flows from Howling Lake in Blackwind Pass and later can be seen tumbling down a waterfall, then it flows south and turns east marking eastern and southern boundaries of Evergreen Valley. Then it turns north creating natural boundary between Evergreen Valley and Eastarra and finally empties into the sea.
