Creyden a small northern principality and vassal to Kovir and Poviss and member of the Hengfors League. It was once part of the East March. While its location is not explicitly described in the novels, it lies nestled somewhere between Talgar, Malleore, and Caingorn.
The coat of arms for Creyden is never actually described in the books. This particular coat of arms was designed by our resident heraldry and Witcher expert Mboro.
