So I had a think to myself a while ago and tried to figure out what Isak would be if he was in a Pathfinder/Dungeons & Dragons sort of setting. Answer was obvious enough. Barbarian of course. But not just your average barbarian, he still keeps his gentle giant sort of disposition and it's only when he or his friends and allies are in danger that he actually rages. Of course, then he goes from the usual happy, friendly horse-man to a crushing, stomping and huge-axe-wielding death machine who will straight up kill anyone who tries to harm him or his friends.
