In the 30th century AD, mankind discovered its high-tech civilization in the vast universe, an extremely powerful race of "celestial spirits"! At that time, the protoss clan was also very welcoming to us humans, and the two sides began to interact closely. However, when the protoss clan was discovered, another alien creature began to appear in the human perspective, the Zerg. This is an extremely aggressive race. They are bloodthirsty, cruel, ruthless, and loyal... In less than 50 years, three colonies in the solar system have been invaded by Zerg, and millions of colonists have been massacred. Compared to the protoss clan, the situation is not optimistic either. An unprecedented interstellar war has begun!
