The Veruna system was a region of space. The planet Frontios was in the system. Tractators came to inhabit the planet and a human colony ship crashed some five hundred years later. An asteroid belt passed through the system. It was used by the Tractators to bombard Frontios. The Fifth Doctor, Tegan Jovanka, and Vislor Turlough visited Frontios in the far future. (TV: Frontios)
