That's interesting. It sounds indeed like this prophecy could be applied to Leia and Ben. And seeing that this novel was released 2019 (according to the article about this novel), it could be very well possible that it's a reference to these two characters. But I don't know for sure

It's how I read it, when I read it.

I honestly didn't like it. Not Claudia's best moment in the book.

I never read into it that way. Love the interpretation!

It certainly fits. Alderaanian prophecy and all. The rest is self explanatory

I thought the exact same thing when I first read that!

I think it was about Ani. Plagueis? Shmi? I'm sure that's still Canon (it already was). Gray has also given us Legends comebacks before (Siri Tachi, for instance).
