It all started in early 2017. Countries have lost contact with various Antarctic research stations, and even all ships approaching Antarctica have disappeared into the icy polar ocean. Yes, no one has been spared. Since that year, the skies over the polar regions have been covered with thick clouds all year round, and even satellites cannot see what is happening in that area. At the same time, many scientists were assassinated around the world. Five months later, governments from various countries jointly dispatched a secret operation team to investigate the situation in Antarctica. This action group of 500 people set off from the transfer station Punta Arenas on a special icebreaker "Theseus", carrying various equipment and weapons. But when they were still 500 kilometers away from the Antarctic Great Wall Station, the voice on the other end of the communicator disappeared. There were no screams from anyone, or any strange noises, and no distress signals. At that moment, quietly, the two hundred-person action team lost contact. After that, governments blocked all news about Antarctica. But there are still rumors quietly spreading among the people: Antarctica has become the new Devil's Sea. After two years of silence, when the Theseus with the silver mark on the ship appeared again in the port of Punta Arenas, despair and death began to spread from that bloody dawn. At the same time, the young man named 'Apocalypse' had already grasped the sword.
