the Deep North

there are a few different areas that encompass the Deep North, notably the Tsardoms which are a cossack/Russian styled area that borders some of the remnants of the great Khan from the Hordelands below it on the map. There are also the Khanates, which are separate political entities that have split off from the descendants of the Great Khan.
