A non-Northern ethnic group of semi-nomadic tribes that dwell close to the Arctic of Midhgardhur. Many of them follow the reindeer herds. They are seen as barbarians by the Northerners. 

Source: Roughly based on several Finno-Ugric peoples from our real world, especially the Finns and Saami. The name comes from an old Norse name that was often used generically for such peoples, but is now applied to specific linguistic and ethnic groups.
