Farsea Marshes

The Farsea Marshes was a wetland located in interior Faerûn west of Cormyr.

Geography
The Farsea Marshes were located south of the Anauroch desert, west of the Stonelands, north of the Storm Horns mountain range, and east of Sunset Mountains. This wetland eventually joined with the Marsh of Tun some time after the Era of Upheaval to form the Farsea Swamp.

History
The region originally consisted of a freshwater lake, known as Farsea Lake, that was surrounded by forest planted in rich, moist and deep soil. After the rotational shift of Toril in the Year of Spreading Spring, 1038 DR the water level of Farsea Lake dropped, causing it's shores to become marshy. Insects bred uncontrolled among the remaining stagnant water and as the weather became warmer and drier in the following decades, the entire lake became merely a wetland.
