So I just killed Volsung and got his mask, the players guide says there is a chest? But I have found no boss chest near the word wall or where I killed Volsung (further down the hill). Is there actually a boss chest there or is the book wrong?

From what I remember (if I'm thinking of the right place) the dragon priest is outside of the dungeon, so if you're looking for the boss chest in the dungeon, then you need to go down into the dungeon. The treasure room is the last thing you visit before you come outside and see the dragon stone or whatever it's called.

Isnt Volsung the one with the hidden chest in the wall? If it is, its back the way you came in to the main room dead ahead where the wall used to be. A panel opens to a small chamber with the chest.

All that trouble and the chest svcked ... lol thanks for the heads up I found it when I went back. Waitwut? I didn't find a hidden chest just one where the Draugr lord was sitting placed against the wall.
