Written In Blood is a written note found in The Knife of Dunwall.
You are safe now. No one can find you here. No one. No one can reach you here. I almost died trying, and I am a better climber than any of them. But you gave me claws for the climb! You want me as much as I want you. We will stay here until they have forgotten about us. We will stay here for as long as it takes. I feel like sleeping. Don't leave while I sleep, because I need you. I will stay as long as I can. Forever.
