The word "Price" is presumably a mistake given the more sensible Editor Id (Pride is the collective noun for lions). This faction establishes the familial relationships for the writers of the Black Horse Courier. Interestingly, the faction specifies that Ra'jiradh is father to the other two members, whereas the in-game dialogue states that all three are brothers. The faction also grants its members access to Ra'jiradh's House, and establishes ownership of the Chestnut Horse in the stables outside the Imperial City.
This faction exists to establish friendly relations between goblins and the rats they farm, which would otherwise attack each other. Once the door to their pen is opened, rats in this faction lose their friendliness and attack goblins on sight.
The only function of this faction is to ensure that the player doesn't get a bounty from killing Raynil Dralas during the quest A Brotherhood Betrayed.
This faction exists to give the civilians in the Chapel in Kvatch a set of helpful responses when the player asks about Savlian Matius or Brother Martin.
The Renrijra Krin is a radical Khajiit organization dedicated to regaining what they see as their territory from the area around Leyawiin. The only use of this faction is to give S'razirr a relationship boost towards the player if the player pays him the promised gold during the Nothing You Can Possess quest.
