You don't need a mod to get one as a follower. You just don't have a follower with you and you can get one of the rieklings from the Mead Tavern and then pick up a normal follower even after you get the riekling. Also they are essential so they can't die except from your hand. I call mine Quincy.
Oh but I killed them. And I think I helped the people to move back to the Tavern and since I killed their "leader", they kinda hate me too. I'll side with the rieklings next time, thought I know I will have to kill their king. Stupid little fellows.
