Renholed
The height of your ascent puts your head and shoulders above the floor of the library, giving you a momentary glimpse of a startled and startlingly irritated Moolog. The implications of returning to the web hit you about half way back down the tunnel. And indeed the Lord of All Spiders is waiting for you with open arms and open jaws. Fortunately, you do not have enough momentum to reach the web, and fly no closer than a meter from the beast before thankfully returning to the tunnel. On the other end, the library comes no closer than a tiny prick of light in the distance before the tunnel sucks you back down (up?) into its depths once more. After many minutes of being jerked about like a yo-yo, you float in freespace ever closer to the heart of the tunnel, where there is a lighted recess in one wall, which you reluctantly crawl towards.
