Then the 2nd one from the left lights up, just keep moving it until the very left one lights up. Move that one until you get the mission update or the lexicon starts glowing.
Now good luck finding all the blood.
Edit: lol at all this "I killed a giant!" talk. I can just sit there while two mammoths and two giants hack away at me and still tank those fuckers. Like I said...
