In the StarCraft universe, the Koprulu Sector —nicknamed the Terran Sector— is a sector in space colonized by the Terrans. The sector is one of the main locations where the action of the original StarCraft game takes place. Koprulu encompasses the colonies of Umoja, Tarsonis, Moria, and all other Terran colonies.

History

Following a period of social anarchy and the "fall of western civilization", a new world-government is re-asserted over Earth: the United Powers League (UPL). A police-state, it encompasses all but a few politically unstable South American countries. Rounding up "undesirables" —cyborgs, geneticly "impure" individuals, hackers, political dissidents— Project Purification was instituted: a mass genocide campaign in which millions died.

However, the dynamic scientist Doran Routhe wanted to explore deep space. It was very risky, but he had no problem with sending political prisoner lab rats to their deaths. Fifty six thousand prisoners were (secretly) prepared for transport, and of these forty thousand were loaded into four sleeper-ships designated the Reagan, the Argo, the Sarengo, and the Nagglfar and loaded for a 1 year journey into deep space to Gantris VI, an outlying planet. The Nagglfar, was also equipped with an artificial intelligence called ATLAS. Routhe believed they would set up a colony and mine new resources for the United Powers League.

ATLAS scanned the prisoners, and discovered something unusual about them - a high proportion of them had a mutation leading to psionic potential. While currently weak, it would manifest in only a few generations. This information was logged and sent back to Earth. This may explain how the United Powers League came to know of this experiment.

However, the guidance computer failed, and they traveled at faster than light speeds for 28 years, travelling 60,000 light years to the far edge of the galaxy. When they awoke, the survivors had no idea where they were or where Earth was: all hope of making contact again was lost.

The Sarengo crashed on Umoja, killing 8,000 prisoners, the Reagan founded the colony of Umoja, the Argo founded the colony of Moria, and the Nagglfar built the main Terran colony in the sector: Tarsonis.

As the Tarsonians had access to ATLAS, they had a technological head-start on their stellar neighbours. Even so, it took them sixty years to build second generation subwarp engines and explore the rest of the system, discovering the other two colonies.

The Terrans of Tarsonis eventually created an interstellar Terran Confederacy, mainly through the creation of new colonies. They calso came into conflict with Moria over its own colonies. The Morians founded the Kel-Morian Combine to fight back, sparking the Guild Wars, but lost.

There were roughly a dozen important Confederate colony planets in the sector by the 25th century. However, war broke out with the Zerg invasion and subsequent clashes with the Protoss.

"Not every locale in the Koprulu sector is a hotbed of violence and mayhem. There are actually areas that are quiet, peaceful places to relax as the problems of the universe just pass you by." - Uran Golenko, leading stress therapist and featured guest on the popular "Universe Today" talk show.

"TRAVEL NOTE: A sudden influx of tourists, coupled with the discovery of considerable mineral wealth on the planet, has left the ecology of Helioc III in a less than optimal state. Once the use of tactical nuclear weaponry has subsided, geologists expect a high level of planetary recovery."

The Koprulu Sector is a violent place, with many "small" pirate militias armed with everything from nuclear missiles to advanced battlecruisers and equipped with bootleg labs and large numbers of troops.
