Dominion is the first of two great walls surrounding Domith, with the other being Nuleic Wall. It was built after the Nuleic Wall, when Domith began to gain strength amongst the cities. Many say that is was built merely to show the wealth of power of Domith, since the Nuleic Wall had never been breached since its constructing many generations in the past. Regardless, it is the largest structure in all of Arem, with a diameter of 160 miles and a total circumference of 500 miles.
There are only three entry ways on the Dominion Wall: Nester Pass, Abastho Pass, and the Pass of the South. The Arem Roads pass through these ways, each leading to their corresponding city or region.
