During the reign of the Galactic Empire, the Tasari had all but abandoned these archaic rituals, but most Tasari families still possessed some tasar crystals as important heirlooms. There were even some bands of Tasari which still believed in the power of the crystals as a type of healing magic. The crystals came in a variety of colors, with each variety supposedly possessing a different level of power or specific use. When civilized society came to Tasariq, the crystals became a valuable commodity and were sometimes used as a currency. The TranStar Construction company began to build cities on the planet in hopes that further gathering of tasar crystals would make them rich.
