The PT-8911 star system, adjacent to the Mars Free Star System, is a small star system with only one planet.
Like other numbered star systems, being individually marked and numbered in the vast PT-89 star system proves that this star system is a part of countless points along the Mars Free Channel.
Among interstellar trade routes, the most complex are those of the Free World. These routes, composed of numerous jump points woven into a dense network, are drawn by generations of interstellar explorers over thousands of years with their lives and luck, forming the lines of life in the cosmos.
Unlike the main channels of mainstream human society, the trade routes of the Free World can never be made into an accurate and complete interstellar navigation map.
