After learning enough in Isata, Charles returned to the Abyss.
He returned to the vicinity of his active volcanic cluster.
He looked at the settlement city still under construction.
Flying through the air, Charles surveyed the surroundings.
The city had originally been intended to make money from the Abyss—a city centered on trade.
