Battle of Koros Major

Returning from their voyage to the planet of Onderon, and in possession of newly learned Sith knowledge, the cousins Aleema and Satal Keto arrived on their homeworld of Empress Teta intent on promoting themselves and their dark side order, the Krath, to a seat of power. Mobilizing the military forces of the Empress Teta system, the Ketos led a violent coup that placed the Krath firmly in control of the established government infrastructure.

Nonetheless, the seven worlds of Empress Teta refused to allow an illegal coup to take place, and thus rose up in rebellion against their newly established leaders. From their hidden bases, the seven worlds launched an organized resistance against the Krath leadership. This, however, gave the Keto cousins an excuse with which to crush the naysayers and instill fear of their rule. Using their new Sith powers, Aleema and Satal were able to lead the Krath in putting down the revolts on six of the seven worlds under their control.

The only planet that was able to mount a successful long-term defense was Koros Major. Before long, word of the planet's fight against the Krath soon made its way across the galaxy and to the seats of both the Republic government and Jedi leadership.

When word of Koros Major's plight against the Krath made its way to Jedi Master Arca Jeth, the aged Master was concerned. The illegal coup, he believed, deserved a response, but what caused him and other Jedi Masters to worry were the reports that claimed Sith participation in the coup. Believing that the shadow of the Sith had again returned, Master Jeth traveled to Onderon, where the Jedi Knights Ulic Qel-Droma and Nomi Sunrider along with several others were helping with a peaceful transition of governing power.

Following his arrival on the planet, Master Jeth gave a quick briefing to the gathered Jedi about the coup that had transpired in the Empress Teta system. The Knights, like the Masters, were concerned when they learned about the Krath and their knowledge of Sith magic. After the conclusion of his briefing, Master Jeth advised the Jedi of their individual assignments, including both Qel-Droma and Sunrider, whom Jeth and the other masters had decided would lead the relief effort to Koros Major. Under the Jedi's leadership, a joint Republic-Jedi task force was assembled and dispatched in an attempt to halt the Krath advance.

With Ulic Qel-Droma and Fleet Captain Vanicus directing the joint Republic-Jedi fleet, Nomi Sunrider had been directed to use her battle meditation in an attempt to sway the battle's tide against the Krath forces. When the joint fleet emerged from hyperspace, however, the fleet commanders found that its destination, Koros Major, was again under attack by a large Krath invasion fleet. To those observing the battle before them, it appeared that the Battle of Koros Major had already been decided.

Wanting to give the Krath a chance to surrender, Qel-Droma advised Vanicus to issue a cease-fire order to the invading Krath forces. However, as Ulic had known would happen, the Krath chose to ignore Vanicus's order, instead continuing their attack on Koros Major. Believing that the only remaining way to stop the Krath's attack was to join the fight, Qel-Droma ordered the Republic fleet into attack positions. During this time, Satal asked his cousin Aleema to make use of her Sith powers to generate large Force Illusions in the shape of space grazers, lifeforms that had, at that time, been extinct for thousands of years.

Realizing what her cousin had planned, Aleema influenced the illusions into seemingly attacking the enemy task force, thus successfully scattering the joint fleet. Not understanding what was happening, Qel-Droma and many of the Republic officers expressed disbelief at the space grazers, which were once believed to have fed themselves on starships; Sunrider, however, was able to perceive the grazers through the Force, and determined that they were actually Sith illusions. Realizing that the grazers presented no danger to the Republic-Jedi fleet, Sunrider ordered the ships under her command to keep pressing the attack against the Krath fleet.

Understanding that they had underestimated the Jedi, whom they had expected to flee from the space grazers, Satal and Aleema devised a new, and seemingly much more effective, plan. Still relying on Aleema's Sith magic, Satal ordered an enormous number of Krath CX-133 Chaos fighters to launch from his command ship and target the individual ships of the Republic-Jedi fleet. In an attempt to cause further confusion among their enemies, Aleema used her Sith magic to create more illusions, but instead of enormous grazers, she created illusions of Chaos fighters.

The Republic fleet prepared to open fire on the advancing enemy fighters, but Sunrider sensed through the Force that it was yet another Sith trick. Using her strong connection with the Force, she used her powers to reach out to Aleema's mind, and was able to take control of it, thus forcing her to lose control over the illusions. Nevertheless, even with the false Chaos fighters gone from their screens, the Republic fleet soon realized that there were still many more real fighters heading on an intercept course with them. Unable to raise their particle shields in time, the joint Republic-Jedi fleet suffered heavy casualties from the Chaos fighters as they crashed into the Republic battleships.

Qel-Droma, stationed aboard the Republic command ship Reliance I, had been severely wounded by flying shrapnel when an enemy Chaos fighter had crashed through the ship's bridge. Unaware that the shrapnel had been imbued with Sith magic by Aleema Keto to turn those Jedi it infected towards the dark side, Sunrider was able to use the Force to bind her fellow Jedi's wounds. Realizing that the joint fleet was now operating at an ineffective fighting capacity, Captain Vanicus ordered the Republic-Jedi fleet to retreat from the Empress Teta system and jump into hyperspace.

In response to the massive losses suffered by both the Republic and Jedi at the battle over Koros Major, the Jedi leadership ordered a gathering of Jedi to assemble on the planet Deneba, where a conclave was to be held in order to discuss the escalating hostilities resulting from Krath aggression. The conclave, however, was interrupted by a surprise Krath attack on the gathered assembly of Jedi; due to the continued enemy aggression, Ulic Qel-Droma made the decision to infiltrate the Krath and destroy them from within.

The Battle of Koros Major first appeared in the issue Dark Lords of the Sith 2: The Quest for the Sith of the Tales of the Jedi series of comics. The battle was conceived and written by authors Tom Veitch and Kevin J. Anderson, and was drawn by artist Chris Gossett. Veitch and Anderson used this battle as a spring board to introduce the Krath Holy Crusade, which was written as part of the larger Great Sith War.

In the original comic appearance of the Battle of Koros Major, no Praetorian-class frigates or Hammerhead-class cruisers appear during the fight. However, when The New Essential Chronology was published in 2005, a picture created by artist Tommy Lee Edwards established within canon that the Praetorian and Hammerhead were present and a part of the Republic-Jedi fleet.
