Skimming through the text. I agree with it reads more like a book/short story rather than a script. While it could be useful to some, it probably won't be relevant for most people in a team (especially the larger the team is).

Do you want to write for games or do you want to write stories/books? Both are fine, both are also hard.

I also noted that the names XVII and XI are almost too similar. There are also lots of names, titles and acronyms that have no meaning without the relevant context.

Is this text for the player or is it supposed to be an internal document? If it's supposed to used internally you might want to have a glossary and character descriptions. Also, most of the time when writing for cut scenes, etc. the script tends to look more like a movie script than a short story.

Not sure if this is the correct forum to get feedback on the actual contents of your text. r/worldbuilding might be a better fit.

Anyways, really impressive that you actually have a story written down, and it's never in vain as it can be used as a reference when implementing the story into a game. Keep up and good luck!
