Abandoned Journal is a book found in The Knife of Dunwall.
I've managed to make a space for myself here. Thankfully, Rudshore is all but completely abandoned. Up in this room, I'm protected from the occasional scavenger and the flooding during heavy rain. I'd like to return to my office in the commerce building to see if I can find some of my old books, but I've yet to build up the courage. Eventually, I'll run out of canned meats and then I'll have no choice. No need for courage when desperation kicks in.
