Well the Old Man, after the fall, is to weak to go to the Temple of the Wind so he told Prettz and Linaly to go together. You need to head Northeast. Theres a gate called the Northeast Gate. Talk to the guard, go in, go to the other gate and an event will begin. After sertant inconviences, Knave will join and you'll need to travel directly west to the sunken ship yard. When you go west, you may not see the sunken ship yard. You'll see a gate but before walking over to that gate walk down some and you should see the sunk shipyard. I HIGHLY RECOMMEND YOU AT LEAST BE LEVEL 2 or 3. And by time you get to the boss there, you should be Level 4. Knave might be 5 by then. Theres a save point half way through. I suggest to use a tent there. I recommened getting treasure chest, they honestly have useful items
. Even some of the wooden boxes have potions.
