Are you playing on pc? if you are you can probably enter a console command to allow you to walk into the cube beside him and then give him the blood. Otherwise try and reload, see if there is some way to give the blood to him. I dont have any other suggestions, sorry!I completed the quest and took the book and the game glitched because when I came back to the Outpost he's stuck inside of the artifact and I can't do anything to open it up. It still wants me to give him the blood.
Any ideas?
