Read the map.

Go back up the icy mountain and dig west of the windswept tree (left-click a pile of snow).

Once inside the caverns, follow the path east and then north, continuing along the northern path until you reach a "picture wall" door.

Kill a nearby skeleton and pick up the key that it drops from the ground.

Search the door and solve the puzzle:

Down

Right

Left

Up

Bottom

Search the door again to pass through.

In the next area, pick up two rotten barrels and six ropes.

Head towards the north-east walkway made of planks and use rotten barrels on the gaps in the walkway.

Make sure you walk over all obstacles here, running will give you a 100% failure rate.

Toggle by clicking the Energy button.

Open the gate by clicking the keyhole that matches the key (e.g. if the bottom of the key is triangle, then it goes into the triangle key slot).

If you were running, which causes you to slip and fall after this step re obtain the key before trying again.

Attempt to open the chest inside the wrecked ship.

Kill Ulfric.

If he spawns again, re-open the chest before killing him a second time.

Attempt to open the chest again and you'll receive a parchment.
