In Antarctica, under endless snow and peaks of ice, an enormous city was completely covered by ice and tilted into the depths of the sea. There used to be a prehistoric lake in this place, before the Antarctic continent had frozen, and there had even been birds and flowers!
However, after thousands of years, it had become the coldest area in the world, a place where no one ever set foot in! The whole huge city was completely covered by ice sheets. The temperature was minus 70 degrees most of the year, and it was always as dark as night.
The city was located between Antarctica Ice Dome A and the South Pole. It would take anyone a long time to get here, whether they were coming from China Kunlun Station in Ice Dome A or America Amundsen Scott Station at the South Pole. A journey of such a vast distance was enough to kill most people!
