In 2091, three months after the dimension of the Final Arena collapsed, there was an abandoned monitoring station on the edge of the Arctic ice cap. The whistling white-haired wind rolled up the ice particles and smashed against the rusty alloy bulkhead, making a harsh sound like sandpaper, like some giant beast grinding its teeth in the dark. Inside the monitoring station, the emergency lights used weak orange-red light to outline the mess on the ground - overturned instruments, coagulated dark red blood, and several bodies covered with thin ice. Their uniforms were all embroidered with the silver star logo of the "Star Circle Group" on the chest.
