Thanks Raze - you were on the nose! I talked to the dwarven king again then went back to Sir Patrick and got the quest.
NEW PROBLEM:
I've returned to the Dwarven Halls with the shield, the breastplate, and the heart gem. I threw my transporter stone past the guards then teleported in to see the king and get the helm.
He won't give it to me! It doesn't come up in the dialogue box and I've clicked on him a coupla times. Any suggestions?
