Head for the fire and do your thing. Look around in the first section, and then keep moving. You’ll run into three guys, easy enough to drop them quietly. A number of guards are on the other side of the water, but they’re easy enough to take one or two at a time. After that you’ll see a campfire, which is the first fast travel you can use in ages. Go back now if you like.
From the campfire, look about 90 degrees to the left of the hut next to it. There’s a tomb there. It’s the Stormguard Sanctum. Use your fire arrow to blow up the pile of stuff on the first ledge. Then activate the gas to clear it, get up on the platform, then head up to the next level. There’s another pile of stuff to blow up across the way, then jump over there. That was pretty easy!
From the entrance of the tomb, hug the edge of the map to your left, and when you reach another hut, you’re about to face a bunch of enemies. Ahead of you is a cave opening guarded by three guys. One well-placed grenade will take them out with great satisfaction.
In the cave, you’ll see why it’s called a wolf cave! Climb the platform to your left, and shoot the carcass with a rope arrow. That’ll rotate a bar for you to swing off. Jump to the climbing wall across the way, deploying the axe when you get there.
When you reach a ledge, follow it to your left. Post-bats, hang a right to leave the cave. And where are you then? Shantytown again!
Roll down a few rope bridges to the tower with the platforms cycling past it. Hitch a lift on one of them. It’ll run out of gas after a conversation, and you’ll have to rope bridge off of it.
On the far side of this platform, look for a ladder up, that’ll take you to a rope bridge to the boat in the sky. On that boat, you’ll kill a LOT of dudes, so be prepared. One of the final ones will have a sword, but he’s easy enough if you know he’s on his way.
Once the frame collapses, move FAST. Follow the yellow steps as quickly as you can to stay ahead of the shooting. After that, one jump and you’re on the ropes. After only one warning of how this QT nonsense works, you’re on your own to time the button to drop from one rope to the next. When everything slows down, it’s time to let go.
