The Hengfors League , also known as Niedamir's League after its king, is one of the minor northern kingdoms. The area used to be the Eastern March of Kovir, but during the reign of king Baldwin Thyssen Kovir lost control over it, and the land divided into minor kingdoms and duchies, which were later united by Niedamir of Caingorn. The capital city of the league is Hengfors, the capital of Caingorn. The region is situated between the Dragon and Kestrel mountain ranges on the Braa.
Like Kovir and Poviss, the League maintained neutrality during the Nilfgaard Wars.
