Sara system
the twin worlds of the frontier
The Sara system was a star system in the Koprulu sector, unusual for holding two habitable planets, Mar Sara and Chau Sara. It was a Confederate frontier holding whose worlds became the first targets of the protoss purification that opened the Great War.
The Sara system was a star system in the Koprulu sector, unusual for holding two habitable planets, Mar Sara and Chau Sara, along with an asteroid belt. A frontier holding of the Terran Confederacy, it became the flashpoint of the Great War. (Koprulu Sector Systems: Mar Sara; StarCraft)
Colonization#
The Sara system was initially catalogued by freelance prospectors and colonized several years later by an expedition from Tarsonis. By 2480 it had passed into the hands of the Terran Confederacy. Not long after the completion of the New Folsom Confederate Mine, the catalytic elements required to forge neosteel were discovered there, giving the system real strategic value.

The Great War#
Confederate traffic increased substantially within the system in the four days following the protoss incineration of Chau Sara in 2499. The Confederates tightened security across all outlying systems, and fearing that Mar Sara would be next, panic spread among the colonists, prompting the appointment of a Magistrate to keep the peace and safeguard the population. The collapse of the Confederacy in 2500 left the system entirely abandoned. (StarCraft; Koprulu Sector Systems: Mar Sara)
Later years#
The Kel-Morian Combine staked a claim to mining and salvage rights over the system after its prospectors found that the minerals on Mar Sara had acquired unique properties from the protoss bombardment, and by 2502 contractors were strip-mining both worlds. The Terran Dominion later took a renewed interest and established several outposts, which the Combine claimed had been invited to address piracy and mining-camp revolts. In response to the second zerg invasion that opened the Second Great War, General Horace Warfield launched Operation Burnout to clear the system, and the First Fleet engaged the zerg there soon afterward.

Mar Sara: where Raynor's revolt began
A dusty Confederate mining world, among the first the zerg overran and the protoss then glassed. Jim Raynor raised his open revolt against Mengsk there.

New Folsom
New Folsom was a deadly, geologically rich planet whose Confederate mine became New Folsom Prison, a high-security penitentiary that held members of the Sons of Korhal and, in one campaign branch, was broken open by Raynor's Raiders.

Tarsonis: the world Mengsk fed to the zerg
Arcturus Mengsk lured the Swarm to the Confederate capital with psi emitters in 2500, then left Sarah Kerrigan there to be taken by the zerg.
2499: the year the Great War began
2499 was the final year of peace in the Koprulu Sector and the first year of the Great War. It opened with quiet training rosters and covert cover ups, and it closed with two Confederate colonies burned from orbit, the zerg revealed to terran eyes, and rebellion spreading from Mar Sara to Antiga Prime.
2502: the year of quiet atrocities
2502 fell in the uneasy years between the Brood War and the Second Great War. The Terran Dominion hid a colonial massacre behind parade broadcasts, Emperor Mengsk buried the mother of his heir, a squad of outlaw commandos was sent to kill Jim Raynor, and secret programs built on stolen ghosts and captive protoss advanced in the dark.

Chau Sara
Chau Sara was a Confederate colony in the Sara system, the smaller sister world of Mar Sara. It was one of the first terran worlds infested by the zerg and the first to be incinerated from orbit by the protoss, marking humanity's first contact with both alien species.

Chau Sara
Chau Sara was a Confederate colony in the Sara system, the smaller sister world of Mar Sara. It was one of the first terran worlds infested by the zerg and the first to be incinerated from orbit by the protoss, marking humanity's first contact with both alien species.
Colonial Fleet
The Colonial Fleet was the naval branch of the Terran Confederacy's armed forces, older than the Confederacy itself. It provided air and orbital support from its Tarsonis platforms until the fall of the Confederacy folded its remnants into the Dominion Armada.
Dominion Armed Forces
The Dominion Armed Forces were the military of the Terran Dominion, built from the Sons of Korhal and the conscripted remnants of the Confederacy. Across the Brood War, the Second Great War, and the war against Amon they grew into the most powerful terran military in the Koprulu sector.
Horace Warfield
Horace Warfield was a Terran Dominion general and commander-in-chief of the Dominion Armed Forces during the Second Great War. A longtime friend of Arcturus Mengsk, he led the war against the zerg, was saved by Jim Raynor on Char, and was killed by Sarah Kerrigan defending the wounded of his command.
Jacobs Installation
The Jacobs Installation was a Confederate facility on Mar Sara where the Terran Confederacy experimented on captured zerg and stored secret weapons data. A raid led by Jim Raynor seized that data, which the Sons of Korhal used to build the psi emitter.
Koprulu Expeditionary Force
The Koprulu Expeditionary Force was the protoss fleet, commanded by Executor Tassadar, that first answered the zerg invasion of the Koprulu sector and was ordered by the Conclave to burn the infested terran worlds.
Mar Sara: where Raynor's revolt began
A dusty Confederate mining world, among the first the zerg overran and the protoss then glassed. Jim Raynor raised his open revolt against Mengsk there.
Michael Liberty
Michael Liberty was a terran news reporter whose pursuit of the truth carried him from the Confederate press to the Sons of Korhal and finally into open defiance of the Terran Dominion. Through pirate broadcasts and the Liberty Manifesto he became the most persistent voice against Arcturus Mengsk.
Neosteel
Neosteel was an exceptionally durable material used by the terrans for everything from battlecruiser hulls and CMC armor to bunkers and personal weapons. Its manufacture required catalytic elements, and to be "like neosteel" was a terran idiom for great strength of will.
New Folsom
New Folsom was a deadly, geologically rich planet whose Confederate mine became New Folsom Prison, a high-security penitentiary that held members of the Sons of Korhal and, in one campaign branch, was broken open by Raynor's Raiders.
Old Families
The Old Families were the descendants of the commanders of the colony ship Nagglfar and the dynastic ruling houses of Tarsonis. Through control of the media, the economy, and the Confederate Council they dominated the Terran Confederacy for generations, until they were largely wiped out in the Fall of Tarsonis.
Terran Dominion
The Terran Dominion was the human empire founded by Arcturus Mengsk on the ruins of the Terran Confederacy, crowned from Korhal and ruled first through oppression and propaganda, then reformed under his son Valerian after the Second Great War.
