Yggzrael spent some time telling Kent all he knew about the Abyss Layer.
From what he said, it appeared that in the Abyss layer, there are four overlords, each terrifying opponents.
Yggzrael couldn't put into words the true extent of their strength. However, from what he said, it appeared these four overlords were stronger than Celestials.
Before coming to the Tormented Chaos Abyss, Princess Pandora told him that her main body was one of the overlords of the Abyss Layer and that she had 25% authority over the Tormented Chaos Abyss.
Since that was the case, it might mean the other three overlords were on the same level as her.
Kent came to this conclusion because, in his opinion, if she were stronger than they, she would have suppressed them a long time ago. However, since she hadn't, it showed those three overlords were very terrifying.
