Galactic Era, January 14, year 221.
Azure Star, south-west of Frost Plated, Nadiville Island, headquarters of Mingji Heavy Industries.
This former tourist attraction from the old era, during the sweep of global chaos brought about by Lord Entropy's calamity, was left outside the order.
Following the evaporation of seas, heavy snowfall and glaciers buried it for an entire century. Fortunately, due to the shallow seabed it was situated on, Nadiville Island was grounded on the continental shelf and eventually taken over by Mingji Heavy Industries. After centuries of transformation, it became a de facto unsinkable fortress, serving as the headquarters and military base of Mingji Heavy Industries.
Being highly integrated with the continental shelf, along with the peril presented by the glaciers, made this island the most unique fortress on Azure Star.
