Banoi Herald Excerpt 24: On a repair bench in a side room of the sewers. The main room will have the last Thug you encounter on the way back to the church during the quest "Bitter Return."
Banoi Herald Excerpt 25: NOTE: #25 has been put in Bloodbath Arena DLC. It is in Lobby area on the second floor, on top of a mattress next to a teddy bear, and NOT in the market area where it originally should have been.
Without the DLC this file is not obtainable in the game without hacking despite claims to it being in the supermarket manager's office in many guides.
