This mod adds a riekling tribe to Solstheim. This is a kind tribe, so they won't attack. Their "village" which is a cave, is a little southwest of "The altar of Thrond", close to Moesring mountains.
Currently is constist of some random "tribesmen", one elder/chief, a tame wolf, and a cook. The chief also has a quest for you. It's a very simple and small quest, but when you complete it, you'll join
their tribe, called Rokar Tribe. the cook sells some random ingredients.
