Chapter 390: 30th Tower

Vincent had first heard of the Celestial Beasts that turned out to be Demihumans. They were an alien race that followed the Celestials here to take control of the land or some other reason he doesn't know.

The other three were the Arkhan Legion, Thoran Empire, and the Morian Collective.
