The Thrugii Asteroid Belt was a widespread belt of orbiting material in the Socorro system. It was present in three different orbitals, and astrogation reports suggested that they were the remains of three planets, destroyed when the system's primary, Sokor, blossomed into a red giant. The Kanauer Corporation claimed all rights to the Belt and mined the asteroids for small quantities of doonium and turminium. Since the Galactic Empire had no presence in the Socorro system, the corporation felt free to turn outsiders away at blaster point.
