Dark Nest Crisis The Dark Nest Crisis or Killik Expansion ( 35 ABY – 36 ABY ) was the general term for the conflict that took place between the forces of the Galactic Alliance , the Chiss Ascendancy , and The Colony , the ruling body of the Killik s . The major conflict during this time was the Swarm War , largely occurring in 36 ABY . History . In 35 ABY , the Chiss sent a message to the Galactic Alliance , accusing the Jedi of interfering in their internal affairs . The Jedi were puzzled , seeing as they had their hands full with pirates such as Three - Eye and Redstar — not to mention the major Ramoan relocation project . Then , one by one , it was discovered that the surviving Jedi of the Myrkr strike team had left their assignments and headed into the Unknown Regions . When Luke Skywalker and Mara Jade Skywalker , along with a few others headed out there , they discovered that the missing Jedi had heard a call for help from one of the other Jedi from the Myrkr mission — Raynar Thul , who had been presumed dead . Instead , he survived and landed among the Killik s , who began taking on many of his qualities . As they expanded their Nests , they came into contact with the Chiss , who used defoliators to ruin their food stocks and drive them off . The Myrkr survivors were helping Raynar defend the Nests , going out into combat to disable the defoliators . Luke and Mara forced the young Jedi to come back into the Alliance fold , reminding them of their responsibilities to the Galactic Alliance . However , several of the Jedi had become Joiner s , including Jaina Solo and Zekk . They referred to themselves as " we " and had a very powerful connection to the Nests because of their Force abilities . The situation between the Chiss and the Killiks was resolved for a time when Han agreed to give the Killiks a nebula they had found , in exchange for the help of Chief of State Cal Omas to annul a claim by RePlanetHab so the Ithorians would have a world of their own , ten years after Ithor was destroyed . One year later , things began flaring up again as the Killiks found that the worlds they lived on had a self - defense mechanism - something they termed the Fizz . It destroyed anything that attacked the planets it was on , which resulted in a great loss of life for the Killiks . They blamed this on the Jedi who had given them the worlds , further destabilizing the Galactic Alliance and making the Jedi look even worse in the eyes of the galaxy . Plus , black membrosia and pirates were being found outside of the nebula , making the Killiks seem responsible for much of the trouble in that area of the galaxy . Also at this time , Jacen Solo discovered he was a father of a baby girl named Allana — the year before , he had convinced Tenel Ka to send a Hapan battle fleet to help the Killiks , but her price was that he spend a night in bed with her . She became pregnant , but used the Force to slow her pregnancy so that her nobles would not think that Jacen was the father . The Dark Nest sent assassins to kill the baby , having been hired by Tenel Ka ' s grandmother to kill the heir . They were foiled by Jacen and a modified version of the YVH 1 droid . Shortly afterward , some of the Jedi launched a preemptive strike on a Chiss base in order to prevent the Chiss from attacking the Killik Nests . This , however , only served to make the Chiss angrier , and they decided to handle things on their own , rather than allow the Alliance to take care of the matter . This act , combined with the capture of the " Victory " - class Star Destroyer " Admiral Ackbar " in the Murgo Choke by the Killiks , were the opening acts of the conflict that became the Swarm War . Shortly after the capture of the " Ackbar " , the Killiks used it to ambush a Chiss assault cruiser that was attacking the Iesei nest . As the Star Destroyer and the Chiss vessel fought in orbit , Jaina Solo and Zekk fought attacking Chiss forces with a Killik army , working to keep them from detonating a superbomb that would destroy the entire Nest on the planet . While fighting with the Iesei Nest , Jaina and Zekk felt an incredibly powerful call through the Force – a call much like the one from UnuThul , except it was from Luke Skywalker . He was ordering a convocation of Jedi on the planet Ossus , to decide the fate of the Jedi Order . Though they both refused to go , nearly the entirety of the Jedi reconvened on the planet . While there , several Jedi – including Danni Quee and Tenel Ka — announced their decisions to leave the Order . Luke himself announced that he was taking control of the Jedi Order — a shocking move on his part , but one that had to be done , if only to keep the Order from fracturing itself apart . The Jedi spread throughout the galaxy again , on the move to thwart the Killiks from pushing the crisis even further . Galactic Alliance Intelligence Service had discovered that the Killiks were moving to support coups among the insect species of the Galactic Alliance by supporting them with troops and weapons . This was all a ruse , though — the Killiks ' real intent in launching the coups was to distract the Jedi from their real objective — defeating the Chiss fleet engaging the Colony . Teams of Jedi stopped most of the coups , though , and Luke and Leia , along with several other prominent Jedi , were able to get to the sector of space the Colony took up and face off against Lomi Plo . They failed to kill her — Lomi had managed to wound Jacen and Mara — and the battles continued . Soon , a huge Chiss fleet attacked another Nest , and UnuThul committed most of the Colony ' s forces — including thousands of dartship s and the nest ship s against the Chiss . A Galactic Alliance fleet lead by Gilad Pellaeon aboard the Star Destroyer " Megador " also came into the system to support the Jedi and the Chiss . Leia Solo , under the tutelage of Jedi Master Saba Sebatyne , trained officially to become a Jedi Knight and defeated Alema Rar ( who had fallen under the sway of Lomi Plo ' s Dark Nest ) . Alema Rar was presumed dead , but her body was not recovered . Master Sebatyne relieved Leia of her lightsaber , proclaiming " it is a terrible weapon , unworthy of her current skills . " Leia was granted the full title Jedi Knight and was instructed to build a new lightsaber . In the end , though , it was Luke killing Lomi , and removing UnuThul from the Colony that ended the Dark Nest Crisis . Without the two fallen Jedi to provide direction and a will , the Colony could no longer function as it was . Things soon stabilized between the Alliance and the Ascendancy , with further diplomatic efforts convincing the Chiss to pull their fleets back . The Jedi decided to reestablish the Council , and the galaxy took another breather from the chaos of war .
