Does anyone know how to complete the fourth riddle in durlag's tower.

The one for "The Red Warder" I think its pride or something.

Thx

Don't forget to press the grapes in the wine press. It is located south of where the warders are. Good luck!

This concerns Durlag's Pride - His Sword I believe.
You must find the room that his sword lies in (Lower left when viewed in map mode). Across the corridor from that is a room with four books in it. You must read each of the books in sequence from left to right. When you complete that you should be informed that you hear a noise coming fom across the corridor, go back to the room the sword is in. It will now have a pillar of light around it, it will thank you for reading of it's deeds in the four books. Go back to the dwarf and the quest will be completed.

Reading the books in any sequence should do, as long as you read ALL of them - I read mine from right to left.
