While the Arames is in charge of external affairs and commanding the public eye, the Athis works behind the scenes to protect and aid the Arames when needed, potentially stepping in if the Arames cannot preform their duties.
The top 3 in the competition to decide a new Arames are then given a test of general skill and are sent to work with the new Arames for evaluation. A week after the Arames appointment, they make a decision on who they work best with and they are then appointed the Athis.
The Athis is in charge of dealing with small, internal disputes, handeling the public image and publicity, and, most importantly, aiding the Arames with whatever they may need.
They gain almost the same benefits as the Arames, Money, publicity, a great house.
