Virevols were a saber-toothed rat species that lacked sentience. These creatures were unique to Despayre, which served as a [prison](/article/prison/legends] world situated within the Atrivis sector of the Outer Rim Territories. Virevols could reach the same size as wolves, making them a significant threat to the prisoners residing on Despayre. Legend tells of a Brigian prisoner, once an assassin, who supposedly killed a virevol using only a stick. Following this feat, he allegedly cooked and eaten the creature. The entire virevol population of Despayre was wiped out when the first Death Star destroyed the planet in 0 BBY.
Michael Reaves and Steve Perry conceived the virevols for their 2007 novel, Death Star.
