Lower Sodden is the northern part of the former kingdom of Sodden, the area around the Yaruga river between Cintra, Brugge and Riverdell. In the aftermath of the Nilfgaard Wars, Sodden was divided between Nilfgaard and the Northern Kingdoms into the Upper Sodden, the southern region, and Lower Sodden.
The area then enjoyed a brief period of independence, but after the death of Ekkehard of Sodden, King Foltest of Temeria became the ruler of Lower Sodden because, as Ekkehard's nephew, he was the logical heir.
The coat of arms for Lower Sodden is not actually described in the novels. These particular coats of arms were designed by our resident heraldry and Witcher expert Mboro.
