After 44 years of interstellar travel, humans finally reached their destination: Riley Star.
On this planet, theocracy and monarchy were firmly intertwined, a union that had persisted for a million years. Due to religious conflicts and historical hatred, wars between kingdoms broke out almost every few years; soldiers fought bitterly, and blood flowed like rivers!
Without the birth of science and technology in Riley Civilization, no individual could see the arrival of the Kunlun Mountain Fleet with the naked eye, at most, they could barely make out the dim ion engines and mistake them for a small star.
In this planetary system, the central constant star was a yellow dwarf star about 5.4 billion years old, with a luminosity 92% that of the Sun, very conducive to the birth of life.
