The political structure of Krinoch is very feudal, Lords rule over tracts of land, which they may parcel out to lesser lords, who can give areas to knights, etc. Although all of Krinoch is ruled by whomever sits upon the Ebon Throne, each Lord is ultimately responsible for their own territories.
This is a list of only the largest or most influential houses in all of Krinoch.
Lords of the Western Holds
Lords of the Vale.
Lords of the Riverlands.
Lords of the North
One of the few remaining tiefling houses in all of Krinoch. House Azaer is more of a merchant house than a political house.
