Hailing from the Bellatrix star system on the exoplanet Vasidus, the Vrejk are a species of semi-humanoid insecoid beings of a very tough exoskeleton with four arms, four legs and a pair of wings, at least as the most common and predominant population on their planet of Earth-like conditions but mostly swampy environment, but it has been discovered that there are at least 4 other sub-branches of the species with slight physical differences depending on their way of life and function to their colony, they have great strength approximately two to three times that of an average human being, great vision at long distances and in the dark and great ability to explore and track targets through different environments.

They are the main intelligent life form of their world, having developed from their beginnings as a civilization technology and organic tools and with compatibility to organic matter with which they also tend to have links and multiple functions for their own organism, most notably in the physique of the warriors of the species, which have armored parts of their exoskeleton very remarkable for their metallic colors that were reinforced from the inside with combinations of minerals such as Teraformium and Titanium in liquid base, leaving them practically a permanently united protection by becoming part of their bodies, that if even the terrestrial armament of great caliber is not able to easily penetrate their armor, the improvement with internal metal makes them even more resistant.

Their society is totally monarchic, the 4 great continents of Vasidus have their own Queen of Colony but it is believed that there is a Matriarch of even greater rank than the 4 that directs the others as a way of control of the whole species, all the queens maintain in constant organization all the Vrejk when they become adults and assign those of the Warrior classes, Engineer and Worker classes to teach and act as tutors of the youngest until they reach adulthood where their aptitude is selected and what role they will fulfill for the colony, while helping in food gathering, body-to-body combat and configuration of biotechnological systems that are considered basic knowledge for the whole species.

Some anatomical variations that exist among their species are those of the Worker class, which mostly do not have wings and their secondary pair of arms are more developed and strong as well as having a redder color, those of the Night Watch class have similarity with the Earth Moths, having a kind of fur on its chest and some parts of its body as well as more resistant and opaque wings and eyes adapted to see better in the dark than the rest of the species, and the Sentinels of Colony that have an exoskeleton already naturally reinforced with metal and considerably more resistant than that of the others, as well as deployable organic daggers on their legs and arms and three horns on their head, similar to terrestrial beetles.

The Vrejk were the second species discovered by the Garlesh millions of years ago in their first interstellar voyages, when they still did not have advanced technology to travel beyond their atmosphere and an internal conflict was close to ending the species, being partly Thanks to the Garlesh's contact with them, the conflict could be resolved more diplomatically and the species could move on.

The species in the following years developed independently of them and other known species and still had difficulties rebuilding their world after the first Technofragna Infestation, but again there was war after the Shinnok Rebellion since two of the Queens supported their ideals. and they decided to join forces with the Conglomerate, which together with this faction kept the other queens subjugated as well as the rest of the planet, controlling the population growth as well as their genetic probability, leaving only Vrejk of the Warrior and Engineer class to be born, the only members that he was interested in having the Conglomerate in his forces.

Faced with the Resistance on Earth and the remnants of the Garlesh High Council who decided to join forces and oppose the Conglomerate, the rumor that did not take long to reach the other worlds oppressed by the faction, the Vrejk did not hesitate to try to free their world from the corrupted ideas of the other queens and the control of the Conglomerate, starting another rebellion that the Conglomerate could not contain for long as their control over Earth and Gracken had been almost completely dissolved and both species would now help the others to break free, not to mention that in all the worlds they had gone to the Technofragna was re-emerging, so without many options they decided to focus on their main objective of activating the Bastion and leaving Vasidus, freeing him after 30 years of oppression.

Despite the fact that part of their forces for years helped the Conglomerate devastate and conquer entire planets and track down the survivors to eradicate any possible uprising, after being released they paid for their atrocities by helping in the reconstruction of the worlds affected by the Conglomerate and in help to mass-produce the Biogel formula created by humans to help the victims, later being one of the main defense forces against the attack of the Kor'vlann, being one of the species with the greatest organization and unity known to date. moment.
