Sapphire Waterfall
From Tardis Wiki, the free Doctor Who reference
The Sapphire Waterfall was a location at the Multifaceted Coast on the planet Midnight, where an enormous sapphire jewel the size of a glacier reached the Cliffs of Oblivion and shattered into smaller 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, 500-klick trip. (DW: Midnight)
