Berchest

Berchest was a major tourist destination, and later a trading planet, in the Anthos sector of the Inner Rim. It was an extremely beautiful world whose highly saline seas and strong tides result in immense crystal deposits on the planet's shores that the native Berchestians sculpted into entire cities. One of these cities was Calius saj Leeloo, or the City of Glowing Crystal. It was carved entirely from one massive crystal that was created over the centuries from salt deposits from the adjacent Leefari Sea and was considered one of the Twenty Wonders of the Galaxy.
