Talk:The Final Descent

I'm at the part where you need to get the journal from the body but I'm dealing a weird thing here. There's no journal on  Gratius's body. and I don't think I got the letter from the guy who originally gave me the quest. I need to know how to fix this. I've tried reloaded a save to before when I enter the room. and I've also tried quitting the game and loading the save.
