The Drinking Cup was a naturally bowl-shaped pit located on the planet Trogan. Near the city of Kergara, the Drinking Cup was noted for the seawater that flooded its bottom, which allowed for the formation of whirlpools during tidal shifts. Because of this, the Ortolan Whistler decided to build a tapcafe in the central shaft of the Cup. Whistler's Whirlpool had a brief period of popularity before eventually shutting its doors.
