Tyrion's Journal is a book found in Dishonored.
26th Day, Month of Wind
I finally found a new place where I should be able to hide and survive for a long time if I stay quiet. The City Watch condemned the building, so this basement should be a safe spot. I have to believe that.
28th Day, Month of Wind
Everything is going as I expected. The Watch patrols in the street nearby, but they never enter this building. Food is the only problem, but I managed to steal some during the night.
2nd Day, Month of Darkness
Someone else found this place and wants to share it. He has a strange amulet made of bone and he claims that it protects him from the plague. We'll see...
Perhaps we can help each other, but I’m losing confidence in the odds of survival.
4th Day, Month of Darkness
Since he arrived, I've been having bad dreams and I don't feel really well.
There're more and more rats in the building.
Soon, I won't be able to leave this shack even if I want to. I'm starting to think that his amulet is cursed.
The book can be found in a condemned warehouse on the north end of the Midrow Substation on Kaldwin's Bridge, where a survivor can be found hiding from plague rats, during the mission The Royal Physician.
- The journal can be found next to a dead body with a bone charm. It is not known whether the man with the bone charm acquired Tyrion's journal, or Tyrion ended up with the bone charm.
