Vaurca Biology
Biology
To the average human, the Vaurca seem to have the appearance of terrestrial prawns. However, they act closer to ants or termites. Their biology follows a similar structure to something like a termite; scientifically, this description is largely superficial. The most obvious and striking feature of this species is their exoskeleton. It is composed of a complex polymer chain involving sulfur as a key catalyst with silicon, carbon, hydrogen, nitrogen forming a much stronger polymer chain than similar exoskeletons found on earth. A kind of biological vulcanization process also occurs, again facilitated by the abundant sulfur within their biochemical makeup.
Life Cycle
The cycle of life and death in Vaurca society is at first glance relatively simplistic. Each stage of a Vaurca's development is clearly regimented by either biological developments or the introduction of augmentations.
When a larva is hatched, its purpose is determined by a Type CB. Larvae destined to become Bound are lobotimized and begin augmentation immediately, reaching maturity within six months. Once they fully mature, they are implanted with a neural socket, and begin work immediately. Bound lifespan is theoretically infinite, provided that the Hive keeps its Bound labour force well-maintained. In this modern world however, where the Vaurca tend to be held as refugees, Bound are rarely maintained and thus can expect an operational lifespan of ten years, provided they experience no work-related injuries. Upon the death of a Bound, the augmentations they possessed are removed and repurposed, and the body is typically incinerated.
If a larva is destined to become Unbound, it is given six months of organic development, which allows for its brain to mature fully. After this six month period, it is implanted with a neural socket, and is filled with information at a steady rate by the hive for another six months. At the conclusion of this one year period, the Unbound is fully matured, and prepared for whatever purpose it may have been given by the hive. It will receive several augmentations depending on circumstance throughout its life, unlike the Bound who receive all their augments at birth. Unlike Bound, Unbound are always more flesh than augmentation, and thus they cannot simply be "maintained". An Unbound experiences a lifespan of twenty years on average, at the conclusion of which their augmentations are reclaimed by the hive, and their body is incinerated. Years spent in VR tend to not subtract from this lifespan, meaning that an Unbound could be several decades old, if it spent most of its time in VR.
If a larva is destined to become Type C, whether it be CA or CB, it is fed special hormones that inspire organic growth that diverges from the typical model. Type CA are lobotomized much like other Bound, however they are not augmented until the end of their growth period. Their sexual organs fully develop, and their carapace hardens in several places, forming ceremonial crests. Wing growths sprout along their back, which will fully develop during periods where the Type CA is fertile. The CA is then augmented to fulfill their role as consort, breeder, and representative of a Breeder. A Type CA will live as long as it remains virile. Once it become sterile due to natural or artificial causes, the Type CA dies and a new one is bred to replace it.
A Type CB will be nurtured for a whole year organically, allowing the royal growth hormones to take maximum effect. Their carapace will harden in several places, becoming generally thicker and growing further ceremonial crests. Wings will sprout along the entirety of its back - unlike the Type CA, CB wings are fully developed for the entirety of their life, however during designated breeding periods the CB will typically be to heavy to generate lift. Throughout their growth period they will be given all the information they need to act as representatives and leaders of the hive. Type CB's will then have neural tubes implanted along the back of their head, allowing them to interface with the neural sockets of any Vaurca assigned under them. A Type CB will typically live for twenty years like most Unbound, excluding years spent in VR. When a Type CB dies it is incinerated along with its augments.
Whenever it becomes necessary, a Type CB larvae can be morphed into a Lesser Queen through the injection of additional royal hormones. A Lesser Queen is biologically different from most organic Vaurca in that it naturally has several limbs and a clearly distinct thorax and abdomen, permitting the creation of several eggs at a time. A Lesser Queen is typically created when another Lesser Queen dies, or the hive needs to undergo massive expansion - to the point where a retinue of governing Type CB is not sufficient. For this reason several Type CB larvae are typically kept in cold storage, should an emergency arise. A Lesser Queen will fulfill many roles in its lifetime, typically overseeing millions of Vaurca at any given time. They are responsible for directing any Type CB under their command, and typically manage entire hive complexes when possible. A Lesser Queen is also expected to relay the whims and orders of a hive's High Queen. A Lesser Queen can also live for a very long time under the proper circumstances - all Lesser Queen's present in human space are the same that embarked from Sedantis I 2,000 years ago. When and if a Lesser Queen does die, however, its body is preserved and stored away for posterity.
Internal Organs
Internally, Type A are very similar to that of an Earth insect. They have an open circulatory system, with their blood covering their digestive system, dual hearts, lungs, and other organs. Their two hearts provide a significant sloshing motion to prevent the blood from stagnating. The Vaurcae's blood is a copper-based hemoglobin, with a high dependency of sulfur, which causes their blood to adopt a yellowish color instead of the red prevalent with other species. It also emanates a very potent stink. This open circulatory system, however, can lead to wounds that pierce the exoskeleton and minor layer of skin to bleed out quickly unless treated.
Vaurcae lungs are totally organic. However, they cannot naturally process oxygen without there being phoron present in the mix. Additionally, Pure nitrogen is toxic to the Vaurcae, and pure phoron will suffocate them. As such, most Vaurcae in human space are equipped with a filtration bit above the lungs, which injects phoron gas into the oxygen they breathe, allowing for safe respiration.
Vaurcae posses in their head a neural socket that allows interface with the hive network FTL communications. The exact mechanics of a neural socket, and how it processes data and keeps information secure is based off of biological processes in the regional Queen, who possesses instead of a neural socket a neural rod.
Limbs
Vaurca have two large insect-like eyes with two smaller ones underneath, which are hyper-sensitive to most forms of light. While they can function in light-heavy environments perfectly fine, most complain about frequent migraines and tendency to get frustrated after long exposures to light like the sun, or even general station lighting. This hyper-sensitivity, however, leads to greatly increased eyesight in dark areas. Their eyes are completely black in terms of colouration, with no variation between the castes. They also have large, insect-like antennae that protrude from their head. These antennae are used for greater perception of their surroundings and to communicate with each other through subtle movements, or rubbing them together with another. Also acting olfactory sensory and nerve database, when these antennae are lost, they can cause confusion, dizziness, nausea, communications problems, and extreme pain.
Their mouthparts are similar to a prawn's, in that they have two large mandibles, with small feelers and chewing parts that come out of the bottom.
Vaurca Worker and Warrior may possess vestigial arms below their main limbs, genetic remnants that serve little purpose. Some Vaurca may remove them for practicality while others are decorating them for fashion purposes. The latter is quickly becoming a fad for Vaurca who regularly interact with aliens.
Augments
While virtually all Vaurca look identical in an augmented state, aside from various shifts in colour, virtually all Vaurca are augmented in some manner, the degree to which depending very much on their caste and purpose.
Bound Vaurca typically undergo the most augmentation. Much of their organic mass will at some point be replaced with machinery, so they can fulfill one specific task to the best of their ability. Worker Bound will at the completion of their development look more like construction machines than Vaurca, with variable amounts of limbs and a plethora of tools at their disposal. Warrior Bound will assume a variety of forms, varying from simple infantry with weapon and targeting augments to assault vehicles. The more complex the caste name of a Bound, the less recognizable it is as a standard Vaurca.
Unbound however will never undergo such severe augmentation. The great limitation of such heavy modification is that it eliminates versatility, the entire purpose of the Unbound caste. Their augments will typically be performance enhancing instead of alterations of the form. Most Unbound are today equipped with at least basic communication augments which make them versatile assets to communication with extra-hive entities.
Ultimately, all Vaurca currently employed by NanoTrasen aboard the NSS Exodus or NSS Aurora are of the least augmented tier - either Type AA or Type BA. Their carapace is almost totally unmodified. Bound and Unbound alike will have a neural socket and oxygen filtration system, and may utilize full-limb prosthetics. Bound may have several augments designed to increase work efficiency or general survival, while Unbound will typically have very few augments to ensure that they can fulfill any task assigned to them by NanoTrasen.
Sleep Cycle
The sleep cycle for bound is a very hard to one to predict. Their natural sleeping cycle seems completely random and is more in line with SSD that plagues other species. They simply go into an inert state and remain unresponsive for a few minutes or hours at a time before suddenly being roused and getting back to work. The sleep cycle for unbound is very predictable. Unbound Vaurca averagely spends 98 hours active, before going to sleep. Some Vaurca may change this sleep cycle depending on their work or needs, and they are adaptable enough to change it in ways similar to humans. To sleep, Vaurca adopt a leaning position that uses specialized joints and hinges in their exoskeletal plates to sleep standing upright.
