Codex Illuminus Pages

As you'll explore the world of Vambrace: Cold Soul you'll find codex pages fleshing out its backstory. This is a list of where to find (nearly) all of the Codex illuminus pages.

Chapter 3
After completing the boss area, but before starting Chapter 4, some more Codex pages can be picked up.

Chapter 4
NOTE: The combination for the rune gate is reunion ->heart -> authority.

NOTE 2: You can visit Mahoram's room if you spoke to him during the previous Chapter.

Chapter 6
In chapter 6 some codexes are in neighborhoods in the Temple district. Not sure if they spawn in specific rooms or if they are random.

Chapter 7
NOTE: Do not sleep in the camp before you are done exploring! Sleeping will start the siege of the spire and you'll lose your opportunity to get some of the Codex pages and 2 Achievements.

Note
The only Codex page that I haven't been able to find is the third entry of Sundries (Sundries 3). If you know where to find it, please leave a comment or edit this page.
