To get out of Anvil go to the house with the broken box in front of it. Then jump onto it and then the house. Let your fatique get almost full and get to the part with the wood sticking out. Get a running start and jump on the edge of the next house, but keep running otherwise you will fall, and walk around on the edge until you get on top of the house. Once on top, run and jump until you reach the last house. Jump on top of the brick thing (forgot what its called) then get full fatique again. Run and jump onto the wall surrounding the town. Go to the left until you hit the post type thing and jump over the wall on to a crack or part sticking out (so you won't die from the jump). Slowly go down the wall until you hit the ground outside of Anvil. There will be many "holes" in the ground don't worry you will not fall and die. If done correctly you should be out of Anvil.
