The Reverend Sister pulled back one of the sheets with a wing-arm, and a blast of warmth hit Honour full on. Beyond the entrance lay a steam-filled room with a squared pool of turquoise-tinted water that bubbled and fizzed like a freshly-poured carbonated soft drink. Twelve columns formed an inner square within the pool, supporting white-and-black-striped arches that came down from the ceiling. There were also what looked like three square raised pillars in the water, creating platforms just poking up above the surface, about five hooves on each edge. And the whole thing was fed by three great trough-spots that jutted out from high up on the walls and noisily poured water down just beside those shallow platforms, accompanied by a steady billowing of steam.
