Primeforce

I'm not so sure of that, Noel_Kreiss - do an eyeball check against the walls. The purple dragon statues are on the same floor as the hero apparently started, and the walls behind them are taller, to the point where the crenelations on the top begin, than the wall at the top of the stairs. I think the stairs actually are going up by a bit. Admittedly, if that's the case the individual steps are about as thick as your average paperback novel, but it does look a bit as though it's rising. The real problem is just that the lava(?) is preventing that from being easily visible.
