Irreth
The Irreth are a sapio-organic species of Vasacar that hail from the planet of Atria. They are primarilly known for being the dominant race within the Grand Order of Avalon.
Physical Description
The Irreth resemble a twisted mixture of insect and Human-like features, undoutably the result of their Kirone heritage being contested by the species' long history of genetic meddling. Their slim humanoid bodies possess four three-digited limbs, which are covered in chitinous exoskeleton and hair-like setae. Their faces, while recognizably human, are gifted with a smattering of uncanny attributes. Every Irreth has two human-like eyes, the sclera of which are black; only the soldier, drone, and queen castes possess a trio of ocelli affixed upon their foreheads like an inverted triangle. From the top of their heads are a pair of antennae similar to those possessed by members of the formicidae family of insects.
Biological Castes
Immature Irreth are capable of developing into four distinct castes based on a variety of factors, including genetics, nutrition, and environmental elements. Three of the four castes consist entirely of females, while the drone caste is entirely male. In addition the worker and soldier castes are genetically sterile, meaning the responsibility of reproduction lies solely with the drone and queen castes. The soldier, drone, and queen castes all possess wings that grant them the ability of flight in environments of proper atmospheric pressure and gravity.
Worker
The workers make up the majority of the Irreth population. Smaller in stature than the other three classes, they offset this weakness with a predisposition for coordination and industriousness.
Soldier
The Soldiers are the second most numerous caste, and are genetically inclined to posess a tall athletic build. Gifted with strong, agile wings the class continues to produce the species' most skilled fighters and flyers.
Drone
The drones are the third most abundant caste, and are intrinsically influenced to be artistic and empathetic. They tend to be as tall as the soldier class, but lack the ease with which they build muscle mass, instead tending to favor a slim aesthetic physique.
Queen
The fourth and final caste is that of the queens, who make up the smallest percentage of the Irreth population; despite this, they hold the powerful and essential role of matrons within Irreth society. Their kind tend to possess a gifted, yet cold and calculating intellect.
Senses
While the Irreth's main eyes are about on par with human's visual acuity, the castes possessed of ocelli have an innate sense of ambient light intensity, which when combined with their vestibular system gives them a natural feeling of direction and orentiation during flight. In addition, the Irreth's antennae are highly sensitive instruments capable of recieving and giving chemical information. This extremely developed sense is a major part of their social conduct, aiding in identification, emotional expression, and communication.
Thermoregulation and Metabolic Efficiency
Irreth are cold-blooded, meaning that they depend on the environment to regulate their body temperature. This means that without technological advancements Irreth tend to avoid colder climates. Because they do not need to sustain these metabolic processes, Irreth do not need as much food when compared to other species of Vasacar.
Arid Environmental Suitability
Because of their partial exoskeleton, Irreth are capable of retaining water far better than other species. While their skin does still produce sebum, Irreth do not sweat as most Vasacar and Humans do.
