A Crowded Galaxy

The vast universe is home to countless planets, with a rough estimate of 6.05 × 10²⁶. The number of star systems formed by planets orbiting stars ranges from 22 trillion to 500 trillion. With numbers beyond counting, these planets are scattered across the universe, yet seem so lonely, separated from everything by the boundless depths of space. Then, in the tenth millennium of human civilization, everything changed. In 10132 AD, humanity finally broke the speed of light barrier. The stars were no longer beyond reach, and human fleets gradually spread from the lunar base to every corner of the solar system.
