Kalabestasz, also known as the Place of Storms, was a planet held by the Romulan Star Empire. The sixth planet in the system, it had no moons and had a 24 hour day cycle with a warm temperate climate.
This world was established as a mining colony which was made famous for its spectacular electrical storms that plagued its surface. The mountains contained deposits of an odd metallic compound that conducted electricity at room temperature better than any other known substance. This made the world a mining outpost in order to make use of the metallic compound for use in critical circuitry. However, the scarcity of the compound meant that it was impossible to produce enough for general use. (FASA RPG - The Romulans module: The Romulan Way: Game Operations Manual)
