It seems strange that in such a combat-centric culture they have no arenas.
I'm guessing the Nords see the entire world as an arena.
Awesome. All the Nords are like, "what do you mean build a place dedicated to fighting...the whole world is dedicated to fighting"! --- It is the mark of an educated mind to be able to entertain a thought without accepting it - Aristotle
Real Nord men settle their disagreements with their bare fists. They should've set up some brawling-club as a replacement for the Arena, since the arena is more an Imperial thing anyway. I can totally see a fight club sort of thing in Riften. --- The mind is like a parachute: it only works when it's open
