From Redon :
The detail of which I speak appears in the pages of the chapter in black and white.
In addition, the Color Spread is this one that we all already know, to promote the film
Putting my guesses together
We learn about the Void Century from the Poneglyphs and Sukiyaki
We learn about how Wano was split apart And We learn why Wano's borders were closed
We learn how Wano borders was closed
We learn something about Continent Puller Oars
We learn about the link between Wano and the Ancient Kingdom as Sukiyaki confirms he's the creator of the Poneglyphs
Anything else, bounties, power levels, etc is boring. Idk
