Guard Captain Zorek at Valgarde in Howling Fjord wants you to recover the Harpoon Operation Manual.
Two weeks ago our chief engineer got his hands on a vrykul harpoon gun - the same type of gun that the vrykul use to take down our ships. By studying that gun he managed to put together a comprehensive operation manual.
Unfortunately he was abducted and taken north of here to Wyrmskull Village. We eventually did find him, but near death and without the manual. His dying words indicated that the manual was lost in the Utgarde Catacombs, located at the northwest end of Wyrmskull. Get me that manual!
