Not sure if this is a bug or not. I finished my first play through (yay!) and i did not learn anything about the revaire rebellion or whatever the isle secret confession is with sayra in this playthrough but the epilogue heavily implied what sayra's secret is and I felt very blindsided learning it in this way. Specifically "the figure head of an endless conflict" and the "would-be queen of blood" I did not even know Sayra was important like that and would have loved to learn that in a future playthrough rather than in an epilogue when I had nothing to do with her or her storyline. Not sure if I was meant to get this dialogue or not but it felt very unearned.
