Are there spoilers in the Codex?

POSSIBLE SPOILER HERE? MAYBE…

I’m ~15 hours in and felt like giving the codex a good read. I started with with the first entry in the events tab: Abduction of Wenceslas IV. It tells his story, going on to state that he managed to flee incarceration in November 1403. As far as I can tell, the game is set in summer 1403, correct? If so, I kinda consider this a spoiler even if it does not directly link to Henry’s story.

I am a super spoiler phobic person when it comes to stories I enjoy, such is the case here. (I will walk out of a movie theater if they start to play a preview of a movie I’m hyped about). Although it happened ~600 years ago, I do not know how it plays out past what I am learning through the gameplay and would like to keep it that way. My question is to those of you who have read the codex. Are there more spoilers here? I am now afraid to read further until I complete the game. I would love to dive into the general section as it looks like it will add a lot to the experience, but I really don’t even want to risk it. Cheers!
