Defatandis and the others saw it; the forces in The Judgment Anthem also saw it. The combined might of Hausen and Ravitan was the strongest, the local ruler.
Defatandis's Seventh Art Gang was the second most powerful force, and the dragoness Ning Long was a separate entity.
The Sea People led by Commander Olivina were another powerful presence. They don't engage in conflicts, but they were inclined to favour Hausen, with whom they've cooperated multiple times.
Black Rose Helena was the power of Judgment itself. But honestly speaking, she didn't pose much of a threat.
The beastmen led by Dao Lu Ku had no shortage of numbers, but they only intimidate the inferior creatures. At this dining table, Dao Lu Ku still couldn't have a seat. They're only capable of going with the flow, and it's impossible for them to oppose Hausen's rule. Of course, Hausen would throw them a bone to chew on.
