The Cursed Captain

While walking along the western coast of Solstheim I met a man named Thormoor Gray-Wave, staring out to sea. Thormoor was once a ship captain, but fell asleep at the rudder while ferrying settlers from Skyrim to Solstheim. The ship drifted into a gale and was sunk. The only survivors were Thormoor and a man whose entire family was killed in the shipwreck.

The only other survivor of the shipwreck, a warlock and seer named Geilir the Mumbling, has cursed Thormoor with eternal wakefulness. Thormoor hasn't slept since the ship was lost, and that was over six months ago. If I can find some way to convince Geilir to lift the curse, Thormoor will finally be able to get some rest. If I do this for Thormoor, he'll share with me a valuable secret he learned when he was a ship captain.

I convinced Geilir the Mumbling to remove Thormoor's curse of eternal wakefulness.

Thormoor Gray-Wave was very grateful I was able to remove the curse of eternal wakefulness. Now he can barely keep his eyes open, and is going to his room at the Thirsk mead hall to sleep. I am to meet him there to collect my reward.

I met Thormoor at Thirsk, and he granted my reward. He told me of Gyldenhul Barrow, located on an island off the northeast coast of Solstheim. The barrow is filled with riches, and I can have it all. The door is heavily locked, but Thormoor has given me the key. He also marked the entrance of the dungeon on my map.
