I like the idea of chaos tricking Miao Ying into killing her sister. That's exactly the kind of petty and malicious thing the chaos gods would do for a laugh. Also there's an implication that the moon empress wiped Miao's memories of it which is a cool bit of depth to her character, and raises questions about what might be going on with the speculation about one of the unnamed dragon children falling to chaos. The rest of the details of the cataclysm are nice too, I don't really feel they jack off Cathay more than an army book should here.

The lore details with Nehekara are fun. The idea that the DE has nightmares about Nagash is both hysterical and opens up interesting possible feelings/relationships about undead.

I don't like that they gloss over how massive a fuck up creating the great maw was. But again I guess an army book isn't gonna focus on that. I also dislike the interactions between Miao ying and Sigmar. It makes the world feel small when all the main characters have met.

Keeping the note about the scheming lords of Nan-gau is a nice nod that all might not be as grand in Cathay as this book wants you to believe.

The line about gunpowder is pure Cathan propaganda and I refuse to accept it.

Overall it's definitely sucking off Cathay but it gives future writers interesting places to take the lore.
