Rocky Pool

Walking into this level of the west tower is rather like venturing into a cave; it’s dark, with slabs of rock slanting up the glass tower walls, stalactites hanging from the ceiling and stalagmites pushing up from the ground. A large, clear, cool pool sits within it, full of tantalizingly drinkable water; watch where you step if you’re going in, though, because there are plenty of sharp rocks hidden beneath the surface that could slice your foot clean open if you happened to tread on them.
