Got through the dungeon with Folgir up to the metal gate with the lever which fires the darts. There are six rotating columns, but according to the strategy guide, there are two lots of columns. Have I missed one set or do I have to get through this lot to see the second puzzle.
Just a minor spoiler here -- at the early stages of this dungeon, sneak past the coffins. Never woke one Draugur -- they came at me later.
Oh Lydia - please don't play with my Staff of Magic.
