Tun River

The Tun River was an expansive waterway that passed through western regions of Cormyr and the Dragon Coast, in the Eastern Heartlands of Faerûn.

Description
Great storms coming down from the Storm Horns wracked the lands along the length of the Tun River, causing it to experience regular flooding.

Geography
The Tun River originated in the Farsea Marshes, that along with the Tun Marshes later became the Farsea Swamp, flowed south through the Tunlands before emptying into the Dragonmere, at the formation of the Gritstone Moorlands.

Geographical Features
The valley around the Tun River was unsuitable for farmland and was regularly flooded when the water level rose.

Flora & Fauna
The waters of the Tun were known as the home to a variety of aquatic animals including frogs, toads, eels, and even crocodiles.

Maxor plants could be found along banks of the river south of the Storm Horns, a fern-like plant from which the substance maxoris was derived.

History
At some point between the catastrophic Spellplague that in the and the late 15 century DR, the stretch of the Tun River between the Farsea Marshes and the Tun Marshes was swallowed up by the expansive Farsea Swamp that formed out of the two smaller wetlands.
