INFO: Killiks were a sentient insectoid species native to Alderaan. They built large mound-like structures on the plains of both Alderaan and Alsakan. Long before most other species came to these worlds, the Killiks vanished. Their disappearance from Alderaan was depicted in Ob Khaddor's moss painting Killik Twilight.

HOMEWORLD:Alderaan, located in the Core Worlds, was the second planet in the Alderaan system, and the home of many famous heroes, including Leia Organa Solo, Bail Organa, and Ulic Qel-Droma. Renowned galaxywide for its unspoiled beauty, Alderaanians worked with and around the land to preserve as much of the natural surroundings as they could.
In an attempt by Grand Moff Tarkin and the Galactic Empire to intimidate the galaxy into submission, the unarmed and peaceful planet of Alderaan was destroyed by the first Death Star in 0 BBY (35:3:7).
Considered the "Shining Star" of the Core Worlds, wild grasslands and old mountain ranges dominated the planet's land surface. Large oceans and scattered inland seas provided the planet with ideal conditions for a large variety of flora and fauna to develop. As such, Alderaan was the homeworld of some of the galaxy's most famous animals, such as the nerf and the thranta. Alderaanian cities were often built with great care taken to protect nature. One such city, Crevasse City was built on the walls of a canyon, nearly invisible from above. Others were built on stilts along the shoreline or under the polar ice. The capital, Aldera, known for its university, was built on a small island in the center of a caldera.
In the Castle Lands, the remains of Killik mounds stood as a silent testament to the indigenous species that had disappeared for unknown reasons. Philosophers, poets, and artists often visited the Castle Lands for inspiration and meditation.
Alderaan was home to more than eight thousand subspecies of grass and an even larger number of wildflowers. Its flora also included a massive variety of spices, herbs, and grains. The planet had no major oceans, but it had a single polar ice cap. The rest of Alderaan's surface water was composed of thousands of lakes and connecting waterways.
FaunaAlderaan had many rare species not seen anywhere else in the galaxy, as well as many common creatures. Among the more notable ones were the: Nerf, Grazer, Thranta, Stalking bird, Manka cat, Woolly moth, Dainty creature, Sea-mouse.

BIOLOGY AND APPEARANCE:The Killiks were social insects and came in several different types—membrosia givers, warriors, attendants, and the deadly assassin bugs. Though the species as a whole was not Force-sensitive, certain types of Killik could be bred to use the Force in simple ways.
All Killiks started as small larvae. After that, their size could vary, though a hive was usually one size. Their glossy exoskeletons were so strong that they could withstand millennia of erosion as found by later colonists on their former homeworld of Alderaan. The exoskeleton also contained a number of respiratory spiracles which served as their respiratory system. This system was capable of being poisoned by the use of insecticide grenades which forcibly closed the spiracles resulting in the Killiks death. Most Killiks tended to have four arms which each terminated into a tri-fingered claw and two strong legs that may have allowed them to leap for great distances.
It was noted that the majority of the Killik race were females with a few males who only left when a new nest needed to be made. Furthermore, a single Killik was able to lay a thousand eggs in a month with those eggs turning into battle ready nymph within a year and by two years time the survivors were capable of laying their own eggs. This gave them a high reproductive rate allowing them to create millions of their kind in a short frame of time as long as there were adequate resources.
CULTURE AND HISTORY:The Killiks had a communal society, with each and every Killik being in mental contact with another. Due to their hive mind, every Killik nest was virtually one individual. Each hive appeared to have a palindromic name; even the word "killik" shared this feature. The Killiks were also peaceful in nature. One aspect of the Killik which other species sometimes found frightening was that extended contact with them resulted in an individual becoming a "Joiner"—someone who was influenced and was subject to the control of the Killik Will by pheromones that actually "change the make up of the brain".
The Killiks were an ancient species who were present long before the formation of the Galactic Republic. The Killiks originated on the planet Alderaan where they built the Castle Lands of Oroboro circa 35,000 BBY. At some point, the Killiks colonized nearby Alsakan. They also claimed to have created Centerpoint Station, which they called Qolaraloq, as well as witnessed the creation of the Maw. What happened next is shrouded in the mists of time, but a theory posited by Luke Skywalker suggests that in 30,000 BBY, the Killiks were driven away from Alderaan and Alsakan into the Unknown Regions by the Celestials after they had consumed Alderaan's resources and prepared to move on to another already populated world. According to a Shistavanen legend, sometime during this period a Killik Sith Lord lived in exile on the planet Sarafur after being driven off of Alsakan.
The Killiks would remain sequestered in the Unknown Regions for millennia. However, in 27 ABY, a starship called the Tachyon Flier—carrying three Force-sensitive Humans including Raynar Thul—crashed on Yoggoy, one of their colonies. Raynar Thul dragged Lomi Plo and Welk, the two remaining survivors and Dark Jedi, from the burning wreck, though they were all badly burned and mutilated. The Killiks there rescued them and began to heal the survivors.
Eventually, all three were absorbed into the Killik hive mind. Raynar Thul took on the persona UnuThul while Lomi and Welk became the leaders of the Dark Nest or Gorog, a secretive Killik hive. Since Raynar had been absorbed into the Killik hive mind, his values became their values, especially his value of individual life. When Raynar emerged, he was in control of the Yoggoy nest, and began changing it to better help the Killiks. In time, the Yoggoy hive spread about local space, to provide for itself and share the "gift" of Raynar among the Kind.
The process was not an easy one. While Killiks were peaceful, like most hive based species, they had no value on individual life. At least one rival nest attacked the Yoggoy hive, but the hive survived, either defeating or absorbing the attacking nest. Then, the cyclical food shortages, which had never faced the Killiks before, required them to begin trading with other planets and races. However, they also began absorbing more non-Killiks into their hive mind. By 35 ABY, when the Killiks were rediscovered by the Galactic Alliance, they were still barely surviving. At the same time, the Colony had expanded to 375 nests, though it is unknown how much of the total population of Killiks this represents. However, the existence of the Dark Nest was unknown to most Killiks.
In 35 ABY, under the manipulation of the Dark Nest, the Killiks began expanding into the borders of the Chiss Ascendancy, starting a dispute which the Galactic Alliance was forced to mediate. Under the terms of the Qoribu Truce, the Killiks of the Colony agreed to settle Woteba and 13 other planets in the Utegetu Nebula rather than continuing expansion into Chiss space. Woteba was settled by the artistic Saras hive.
Unfortunately for the Killiks, Woteba and all of the other planets in the nebula had an ancient environmental defense system. Whenever the planet was hit by the nova that formed the Utegetu Nebula, all animal life was wiped out, but plant life was restored within two years by the defense system. At first, Woteba seemed a paradise for Killik colonization, but the planet attacked them anytime they interfered with the ecosystem, destroying both structures and living beings with a corrosive substance known as Fizz, nano-machines which broke down the intrusive objects or beings on the molecular level. As a result, the Killiks believed the Jedi had purposefully sent them to the planet to fall victim to the Fizz, but this was not true, merely a lie of the Dark Nest.
In 36 ABY, the Killiks abandoned the Nebula for fourteen nest ships built in the Tusken's Eye, alongside the nest ship of the Dark Nest. This fleet captured the Galactic Alliance Victory-class Star Destroyer Admiral Ackbar in preparation for their invasion of the Chiss Ascendancy, thus starting the Swarm War.
Attempts to prevent war were ruined when Jedi Knight Jacen Solo attacked a ship of the Chiss Expansionary Defense Force in an attempt to lure them into a preemptive strike against the Killik. Many of the Killik allies were insectoid races including Fefzes, Flakaxes, Geonosians, Yam'rii, Snutibs, S'krrrs, Verpines, and Vratixes due to the fact that they became Joiners more quickly.
During the war, the forces of the Galactic Alliance were led by Supreme Commander Gilad Pellaeon, and the New Jedi Order by Grand Master Luke Skywalker. The Alliance eventually won, despite that a Killik coup of Thyferra resulted in the loss of Bacta.
After their defeat the Killks went back to their original culture in peace and isolation from the rest of the Galaxy including the Chiss in the Unknown Regions.
