Along with Tourr, Xii is one of the most technologically advanced worlds in the Rasq system. Conquered in 112 IE during the Great Interplanetary War, the planet is currently ruled by the Xii Empire, which offers tribute in the form of industrial production to the Tourr Imperium.
Xii specializes in the production of biotechnology, space-based solar power systems, and certain electronic components. As of 367 IE, the lucrative trade between Xii and Tourr contributed to 5% of the Rasq system's GDP. Xy-Aili, the largest city on the planet, is the industrial centerpiece, with a population of over 879 million.
