Kilrah is a star system in Kilrah Sector comprised of six planets, multiple asteroid belts and the remains of the planet Kilrah, the destroyed homeworld of the Kilrathi. As such, Kilrah was the throne world of the Kilrathi Empire until its collapse in 2669 at the conclusion of the Terran-Kilrathi War.

The Kilrah System was once the very heart of the expansive Kilrathi Empire, and likely was home to the largest population of Kilrathi of any star system. It was the political, military, and economic center of the Kilrathi Empire, and among the most heavily-fortified systems in the known galaxy. Situated deep within the Kilrah Sector, no Terran dared to venture towards the star system throughout most of the war.

Kilrah possessed a jump point that led to Munro deep within the Terran Confederation, which in turn led to Earth itself. Murno was one of the most contested systems as a result, and had the Terrans succeeded in maintaining control of the system, Kilrah would have been even more vulnerable to Terran attack.

Kilrah was only ever infiltrated once prior to its ultimate destruction in 2669. In 2668, a task force led by the TCS Tarawa raided Kilrah in an attempt to strip the Kilrathi of their military prowess. Although the Terrans suffered dearly for the attack, the severe damage they managed to inflict on the Kilrathi homeworld proved a major political defeat for the Kilrathi.

However, by 2669, the Kilrathi were on the brink of total victory against the Terrans. Desperate to save Earth, the Terrans launched two major efforts to conquer Kilrah. The first was a strike by the TCS Behemoth, which was intended to destroy Kilrah prior to its untimely destruction as it was setting out on the mission. The second was the Lancelot Flight, during which Colonel Christopher Blair launched the Temblor Bomb on Kilrah and destroyed the planet, effectively ending the war in a Terran victory. After Kilrah's destruction, the Kilrah System's strategic importance and population was greatly reduced, and the survivors were forced to relocate to other star systems. The Kilrah System became home to the planet's remnants which formed a massive asteroid field by 2681, a testament to the Kilrathi Empire's former glory.

The Kilrathi System became open to Terran traffic after the war, and proved to be a valuable source of natural resources. Most of its Terran visitors were miners and scientists.

In 2681, Kilrah rose to prominence once again when an alien race known only as the "Nephilim" invaded the Orion Arm of the galaxy by occupying Kilrah as a site for their wormholes. It was here that a civilian research ship, the TCS Devereaux was destroyed, alerting humanity to this new threat. Kilrah was quickly occupied and became a Nephilim stronghold.

Kilrah was liberated after a concentrated assault on the wormhole gate by Terran forces from the TCS Midway. Ironically, they were led by Commodore Christopher Blair, the very man who destroyed the system. Blair sacrificed himself during the battle and he was presumed dead.
