Yuan Star is a special star among the countless stellar systems of the Endpoint Nebula. After millions of years of evolution, it gave rise to intelligent life: the Yuan civilization.
As the most unusual stellar civilization in the known universe, Yuan Star forms a trinary star system with the Taihao System to the west and the Lieyang System to the east.
Because the geography of Yuan Star's north and south differs greatly, the Yuan civilization developed and evolved in entirely different directions in each region.
The geological environment in the north is relatively mild. Its inhabitants have a high level of civilization and a deep yearning for intelligence and technology. They have also developed technologies such as mechanizing the body and transferring consciousness.
In the south, the harsh geological environment means gravity is more than a hundred times stronger than in the north, and the entire region is covered by a mysterious, visible red magnetic field.
The bodies of the southern Yuan have evolved to be extraordinarily tough and strong, and a rare few possess the ability to commune with spirits.
Northern scientists are eager to explore the south, but they have always been blocked by the mysterious red magnetic field, unable to break through despite trying every possible method.
That changed in February of the 2283rd year of the Yuan calendar, when an unidentified planet called Alpha suddenly appeared in the Yuan System and charged toward Yuan Star. It had a magnetic barrier somewhat like the one surrounding the south.
Two races from the same world, who had never communicated before, meet with just over two hundred days left until doomsday. Are they enemies or allies?
