The Sapphire Waterfall was a place on the Multifaceted Coast on the planet Midnight. An enormous jewel the size of a glacier reached the Cliffs of Oblivion and shattered into smaller sapphire fragments, falling a hundred thousand feet into a crystal ravine.
It was a spectacular view and a waterfall palace was constructed at the site to facilitate tourism. Excursions to the waterfall were regularly organised by Crusader Tours from the central Leisure Palace, a four-hour, five-hundred-klik trip. (TV: Midnight)
