Jade River

The Jade River, a portion of which was later named the Barren River, was a once-massive waterway that flowed through central Threskel, one of the Old Empires of east Faerûn.

Geography
It began in the western peaks of the Riders to the Sky mountain range and flowed westward, south of the city Mordulkin, before emptying into the Bay of Chessenta.

Description
The green waters of the Jade River rushed down the mountainside before leveling out and flowing lazily across the plains of Threskel.

The river's color originated was caused by both naturally-forming algae and industrial waste caused by dwarven mines in the Riders' mountains.

History
After the landscape of Threskel changed following the events of the Spellplague in the, the Jade River became no more. A massive plateau erupted from the plains, creating a small lake known as the Jade Pond and a much smaller waterway that share the Jade's mouth at the Bay of Chessenta, known as the Barren River.
