Hengfors was, throughout its history, an independent city-state, the seat of the powerful Thyssen family when they held East March, and the historical capital of at least two kingdoms. Currently, it is the capital of Hengfors League.
Long ago Hengfors was one of the several petty states of the divided north. It was eventually annexed by Caingorn and, later, by Kovir and Poviss. The House of Troyden established the city as the capital of East March, which was later given to Guido Thyssen by Gerard, the last male heir in the Troyden family.
In the 1220s, Audoen separated Hengfors from Kovir during the Secession of Poviss and formed his miniature kingdom here, which included Arcsea. After it too collapsed, Hengfors was, for some time, independent from Caingorn but was eventually joined to it again after King Niedamir formed his League.

- In the first released version of The Witcher Role-Playing Game the League was called "Hengefor's League", thus suggesting that the city could be named after an individual known as Hengefor. It was however stated as a misspelling and corrected in the updated version.
