Novgorod

A region of the Kievan Empire.

The capital city, also named Novgorod, is said to have been founded by Baba Iakulu aka Igwolf because of the special properties of the soil: that which is buried there does not decompose. It is a major river port city located in the Volga River. Unlike Kiev, Norse is in fairly common use here.

The Tarot Dungeon is located underneath the city.

    (Quoted in a book on Greek grammar found in Prince Vselov's library, source uncited)
    Alexander, at her advice, sought the city of Nawobod, to the north of India. And later, near her
    homeland, in the Hyperborean realms, she built the city of Nawobod, which means New City, for it was
    there that the moist Mother Earth preserved everything, and it was there that the buried do not rot.
