Well, at the stone bridge, there's this big head. And beyond that, the rest of the map. the only other offshoots are a small area with lab notes regarding how to raise perception, and the other leads to a big alchemy room with an ingredients vendor. And of course the end of the level with the blood stone.
I assume the whole thing involves having high perception, but my crafting is at 3 and isn't high enough to make the perception potion (eye+flask+augmentor). Perception is at 11 though so I don't see how it should be such a big problem. Anyway, tl;dr dunno how to get past the skull.
