Braxis

Braxis, a small world, possibly a moon, was a Terran Dominion colony by the time the United Earth Directorate fleet reached the Koprulu Sector. Much earlier, it had been a Protoss colony, by the name of Khyrador. Little is known about when Terran colonization started. It is presumed that it is the closest Koprulu Sector object to Earth, since the UED fleet first landed here.

Braxis is the homeworld of the Ursadon.

History
The capital city, Boralis, surrendered to the UED when they destroyed a Command Center in the heavily guarded stronghold with the guidance of Samir Duran and his Confederate Resistance Forces. The UED proceeded to Tarsonis where they uncovered the Psi Disruptor, a powerful anti-Zerg weapon. UED Vice Admiral Alexei Stukov disobeyed orders to destroy the Disruptor, hiding it on Braxis.

During the UED occupation, Schezar's Scavengers took shelter on the planet, including Alan Schezar himself and powerful anti-Protoss technology, along with a number of Zerg enslaved by the Dark Templar terrorist, Ulrejaz. A Protoss warband arrived, seeking vengeance on Schezar for his crimes; they ended up banding with Schezar and fighting against the enslaved Zerg.

The UED Admiral, Gerard DuGalle, eventually became aware of what he considered treason committed by Alexei Stukov and ordered his minion, Samir Duran, to attack the Disruptor and "terminate Stukov's command". The mission turned into a disaster, as Stukov was in facting working against Duran, who really was a turncoat. Duran assassinated Stukov and vanished, leaving behind large numbers of Zerg and having set the Psi Disruptor's fusion core to overload. The UED forces were able to slay the Zerg and prevent the meltdown.

The Psi Disruptor severely disrupted Infested Kerrigan's control over her Zerg forces; striking an alliance with Arcturus Mengsk, Fenix, and Jim Raynor, she persuaded them to assist her in destroying the Disruptor. The attack was successful, enabling Kerrigan to regain full control over her forces and eventually win the Brood War.

After the conclusion of the Brood War, Alexei Stukov made a reapperance; he had been resurrected and infested by a Zerg Cerebrate, Kaloth. Stukov had Terran and Zerg forces, who appeared to have taken over the entire world. A combined operation between the Protoss and Raynor's Raiders, led by the elderly Dragoon Taldarin and Jim Raynor, was mounted to use nanotech technology to reverse the infestation process on Stukov. The operation was a success, but it had a high cost; not only did most of the troops sent to Braxis perish, but the Protoss purified Braxis afterwards, destroying all life on its surface.

Trivia
The name Boralis is a reference to the WarCraft series. The capital of Kul Tiras, one of kingdoms in the Human Alliance, is Boralus.
