The Forgotten Woods.

Notable mobs are Cato and Dobra.

Walk ( 8n, ne, w, n ) to get from DH to the room marked in blue, right down the bottom on the first image.

It's just a more detailed version of the maze, with every exit marked. I haven't completed this for the southern section.
Really, you don't want to have to use it anyway.
