Jack belongs to the Antarctic Group, a transnational conglomerate that has suddenly become active in recent years.
But these are just appearances. Behind the Antarctic Group is an extremely mysterious research institute, with headquarters established in Antarctica. Some say they are a secret refuge established by the United States of America before the catastrophe, while others claim they were once a branch of the Academy but eventually chose to part ways due to differing opinions. In the Wasteland Plane, there are many mysterious forces like these, because even today, hundreds of refuges openly established in the past have yet to be opened, let alone the secret refuges established by various countries.
People don't know where they are, or even whether the people inside are still alive, and almost every decade, a new refuge is opened.
