Wilderness of Dreams, a black fog zone thousands of miles away from Originheart City.
The so-called black fog zone is actually the breeding ground for Demonic Fiends.
There is a pure white metal building nearby, spherical in shape, with no windows visible at a glance, and only Magic Patterns representing absolute defense on the walls, to ward off the invasion of the black fog.
On the upper level of this building, there is an air harbor, housing several steam-styled mechanized airships, and like the building, these airships have no windows either.
When Angel arrived at the Wilderness of Dreams from the real world, he happened to see a mechanized airship flying towards the distance, heading towards Originheart City.
Angel walked up to the spherical building, and the smooth curving surface immediately opened up a passageway.
