A link to Nowheresville? Maybe. I hit this accidentally when I crawled through a hole in the Skins Room wall. I don't know where it goes. I took this shot, then there was an unpleasant vibrating noise, then the lights went out.
I backed out.
Still, it does have some nice lighting, showing you a flares option on the left and volumetric lighting at the right. Which means you can see some of the light cone as though there were dust in the air or mist.
