Rekkr the Red 

After being captured from a Norðreyjar raid as a young man Rekkr became a thrall for all of his formative years, as he worked the fields and land he gained notoriety for breaking everything he touched, rakes, fences, rocks etc. So the Chief sent him out during a raid from a rival clan to rid him of this nuisance, much as Odin may wish to dispatch Loki for his constant hijinx. As the snow and smoke settled he came back to the only home he now knew drenched in blood but still alive - it would seem his name sake applied to his enemy not just farming tools, fearsome as they are.

Since then he was made a free man and has continued to raid with the Wolves as at this point he had spent more of his life here than he ever had in Norðreyjar. He has now managed to work his way from thrall all the way up to to Master At Arms. Chief Axel  wanted to see if he can hone the next generation of warriors in his legendary destructive ways.
