StarCraft: Rise of the Terrans
The swarm has destroyed our home, and the few remaining humans have flown with the fleet to the unknown starfield.
One of the fleets wiped out the pursuing swarm in a star field, but their fleet was also almost wiped out, leaving only one warship to land on a massive planet.
Originally, they wanted to collect resources on this planet and repair their warships, but this planet has a very unusual place.
In the end, the ship's crew died within a few years, leaving only an advance fortress. Decades later, Su Feng descended on this fortress, accompanied by a StarCraft Terran system.
