River Xon

The river Xon was a river that lay along the border between Durpar and Ulgarth in southeast Faerûn.

Geography
The Xon emerged from the Ice Peaks of the Dustwall Mountains. It ran past the Durpari city of Flyndagol on the west bank. At its mouth, it flowed into Xontuil Bay, which was part of the Golden Water.

Politics
The heavily defended and fortified border between Durpar and Ulgarth lay along the Xon.

Industry
The river Xon was where the cosmetic fiertallin—a chalky white material—was gathered. It was exported from Suormpar, a city 20 miles (32 kilometers) down the bay. It was popular in Ulgarth.
