You have to get the boat to get his blinders.
There on that island with a ghost archmage and ghost ladies.
Be sure to sneak past the bottom part of the village and get the blinders. You can get the archmage to teleport you again I think to make it easier to get away.
Heh, the Google Translator is pretty bad, so i won't post it, but i can tell you. When you step in the Circle near the Chest, use right and left arrow keys to ''picklock'' it. If you hear a voice, then its right one. If Khadgar says that it's wrong one, it's wrong. You have to press left and right arrow keys in right order to open it. I forgot the order but i think you can figure it out. Enjoy.
