Go upstairs to find another pillar puzzle. Use your best spells or weapons on him and remember to keep moving. Inside the door that you just opened, a powerful Draugr attacks. From left to right, the pillars should be whale, snake, hawk facing out, and hawk, hawk, whale on the other wall. You must turn each pillar to match the symbol above it. Puzzle: Notice the six pillars and the smaller pictures above each one.
At the far end of the room is a puzzle you must figure out to proceed. Carefully kill the Draugr, being cautious not to become overrun or find your way in the middle of a fire trap. Inside is a grand burial crypt with plenty of Draugr. Head north and open the door ahead with a lever on the wall. Once they are gone, continue alone into the next area alone.
With few details, tell Tolfdir what happened before being attacked by Draugr inside the chambers. Apparently, you have been chosen by the Psijic Order to be a part of the dangerous journey ahead. Follow Tolfdir into the next burial chamber and you will have a vision of a man named Nerien who warns of impending trouble ahead.
