Drinking Cup
this natural, bowl-shaped pit was located on the planet Trogan, near the city of Kergara. It was noted because its central shaft was open to the sea at its bottom, which allowed the in-rushing ocean water to be forced into a swirling whirlpool during tidal shifts. This whirlpool rose up the shaft as the tide came in, and receded as the ides rolled out. Because of this natural wonder, the Ortolan Whistler decided that it would be an unusual place to build a tapcafe. The resulting establishment, known as Whistler's Whirlpool, was briefly popular, but was eventually abandoned.
