Vrauzon was a desertic world of the Lyran Star Empire.
It was home to Spoiled Rotten University, a research university with a less-than-reputable medical school (by non-Lyran standards; Lyrans seemed to be content with its medical standard), from which Mandy Guilmain graduated. (Star Trek: The Stoneship Files: "Educational Armageddon")
The planet was afflicted by an asteroid impact in 2415, which prompted Starfleet to send in a shipment of vacuum cleaners, including but not limited to the Quendelton area. In addition to SRU, Vrauzon was home to another university, Quendelton State University. (Star Trek: False Vacuum: "Asteroid Dusting")
