The Andonne
- A river in Greater Sembara
The Andonne is formed by the confluence of the Masance and the Aursen, and flows for almost 300 miles until it joins the Valmont at Lake Aeulian. The western quarter of the river runs swiftly with numerous rapids, until a particularly sequence of rapids and waterfalls known as the Washbasin. Since the Great War, the river, east of the Washbasin, has been ash-choked and corrupted, and unsafe to drink.
