The Celestial Dragons are gearing up for the final war!
After Dr. Vegapunk Stella revealed a secret group wanting to destroy the world, Monkey D. Dragon and the rest of the Revolutionary Army begin perparing for all-out war against the World Government. Turns out, the Celestial Dragons are doing the exact same thing.
Going by what Gunko and Sommers said in this chapter, they want Elbaph’s warriors on their side during the inevitable final battle, whether Warland’s citizens want to or not. Hence, why the Holy Knights are kidnapping Elbaph’s kids. Just take the kids as hostages and Elbaph’s adults will do whatever the Celestial Dragons want. Simple, yet effective. Also evil. Very VERY evil.
This all confirms most, if not all, Celestial Dragons with higher status know the truth about the world. Or, at least, they know enough that they have to work to maintain their godly status and that the world will indeed be flooded at some point. And, they need to make sure it happens, no matter what.
