Found all 4 chapters of The history of the chantry, by brother Genitiv

To complete this, you will need to find all 4 entries before the end of the game. While the first 2 chapters of the history can be found easily enough by visiting the Chantry at the start of the first and second chapter during the day, Chapter 3 of the history can be a little more tricky. To find Chapter 3, start the Following the Qun mission and it will be right in front of you when you go to the Chantry. You can pick it up during battle by pausing and moving the reticle over it and pressing A. The last Chapter, Chapter 4 is in the Chantry in Act 3. You can find it up the left set of stairs and in the room there.
