Igneous Cavern is the largest human-inhabited cavern on Detritus. It is home to the apparatus that produce the DDF ships. In addition, it houses reserve ships for the DDF in event of an emergency such as a Lifebuster.
The public elevators that can take people and cargo to the surface can be found near the center of Igneous. The government buildings are close to the elevators and are used to host the pilots entrance test. One can elect to take the pilot entry exam when they are seventeen. The test goes for four hours and can cover material from any number of classes taken by students.
