Arzhang is a div, which is to say a demon, and he is the sixth stage. What sets him apart from what came before is not size. It is that he has troops, a camp and a job. He is a commander, posted, with an army that answers to him.

Up to here the road has been things met one at a time. Arzhang is where Mazandaran stops being a landscape with dangers in it and becomes a side, with an order of battle.
