The Khalhu River (pronounced KHAHL-hoo) is a major river that serves as the border between Amshan and its vassals Kudurru and Ramashal. Historically the river marked the southernmost extant of Amshani civilization, with the lands beyond too hostile and inhabited only by dangerous magical creatures and small groups of outlaws and pirates that made their bases in hidden places near the Khalhu's many rapids. Today the Khalhu, though it remains treacherous, is crossed by multiple bridges, and is therefore more accessible than ever.
The Khalhu River begins in the Shields before flowing north and east into the Kirnashal Sea.
