And after a brief introduction without further ado:
I was thinking while reading some of the stories that in the chronicle pages if the player gets a codex, we could have looping tracks that play a unique theme for each story line in this worlds history. Then when moments in the game where specific events that are directly related to certain stories in the chronicles, themes can be pulled upon and used to give the player an audible reminder to stories they read previously.
This is one such piece.
I don't know if you plan on making lore for your enemies in the chronicles, but if not it can be reassigned.

Cheers,
