Iokath

Iokath was a massive artificial sphere constructed around a star located in the Unknown Regions by a technologically advanced species at some point before the Manderon Period. Every orbital body in the system was demolished and salvaged for core elements, from which an impervious habitat for the species was constructed, using all of it star's energy output. The species of weapon designers created many technological wonders such as the Gravestone, the Eternal Fleet, the GEMINI droids, SCORPIO and the Old Gods, using their superweapons on dozens of different worlds for live testing. When a civil war broke on Iokath, both sides began using their superweapons against each other, which led the engineers to drive many of their creations into Wild Space with their memory cores locked. However, that did not save them, as the Six Gods were unleashed on Iokath, eradicating all organic life on it and leaving a single self-aware droid known as ARIES to reshape the world in his image.

Few visitors that found Iokath over the centuries were all killed by ARIES in brutal tests, until many new arrivals came to Iokath around 3631 BBY, in the middle of the war against Zakuul. Iokath creation SCORPIO, who uncovered her origins, brought to Iokath the Eternal Fleet and the Gravestone, with the personnel from two warring factions still onboard. ARIES used a superweapon to knock every organic on those ships unconscious and placed them across the surface of Iokath to test in combat simulations. Independent from each other, Alliance and Eternal Empire forces reunited with their allies, working against ARIES to escape from Iokath. The Alliance had retrieved their main combat vessel Gravestone while Eternal Empire forces led by their Empress Vaylin regained control over the Eternal Fleet warships. ARIES prepared to use his superweapon again, killing all organics and damaging the GEMINI droids, but SCORPIO found the location of his base and assisted the Alliance in stopping him, allowing everyone to leave. The superweapon exploded, covering the entire world in a pulse of deadly radiation and making Iokath unsafe to explore.

By the time the radiation levels subsided, Empress Vaylin was dead and the Alliance had conquered Zakuul, transforming itself into the Eternal Alliance. A group known as the Order of Zildrog learned the location of the Six Gods and leaked it to the Eternal Alliance, Galactic Republic and the Sith Empire simultaneously. All three parties arrived on Iokath and converged on the superweapon at the same time, leading to the War on Iokath, in which the Eternal Alliance joined the side of one galactic government to stand against another. During the battle, leader of the faction rejected by the Eternal Alliance attempted to gain control over the Six Gods through an Iokathi throne, but failed and was killed by a power flux, leading to the first of the Six Gods awakening. The Eternal Alliance Commander used the Eternal Fleet to knock the droid Tyth out of commission, after which the Scions of Zakuul urged them to finish the deed and subdue the Gods once and for all before they could destroy them all.
