Dark Dawn and Saint Defier were on the second wing occupied by Arid Triad among the four wings of Harmonious Morus Alba. It was a huge Expanse Cosmos, and while it was not like the first Expanse Cosmos belonging to Arid Triad, the overall area was about the size of three True Worlds in Arid Triad.
After all… besides the four Great True Worlds, Arid Triad Expanse Cosmos also had the Barren Lands of Divine Source as well as other empty spots at its borders. In fact, Arid Triad had nine True Worlds during the previous era.
In the second Expanse Cosmos belonging to Arid Triad, which was a small wing under the two big wings belonging to Harmonious Morus Alba, Dark Dawn and Saint Defier each occupied half of the universe.
It might seem like a lot, but it was not in comparison. However, Dark Dawn and Saint Defier referred to these areas as their camps because they each occupied 180 Expanse Cosmoses in that universe.
