The second Knot in the Celestial Tether. Trachsys is the pinnacle of human innovation. All of mankind’s greatest inventions have spawned from this technological utopia. Due to constant development Trachsys has split itself into two halves, an upper and lower city. The upper city continues to expand and grow as newer technology surfaces. The lower city has since been re-purposed and its resources go to the maintenance of the upper city. This dynamic must remain consistent shift to ensure that no resource goes unused and the city remains sustainable. Once the new technology has been tested and is deemed functional the general body moves up and the remaining housing is given to engineers and their families.
