66 WATERFALLS. The sound of running water will be obvious as this room is approached. The room is lit by floating glowing blue spheres of light, each about the size of an egg.
Each corner holds a waterfall. The water enters from a sluice eighteen feet off the ground and falls into four ten foot by ten foot pools each with a depth of three feet. The water is always clean and is lukewarm. It is drained from below by small holes.
As the water hits the pool, it releases the blue glowing lights, which drift through Rooms 67 to 83 and intervening corridors. The light spheres are not substantial and will slip out of the hand if grasped.
