Xa'Thins (Pronounced Zay-Thins) are bipedal anthropoid-like creatures, with a mean height of approximately 1.77 meters (5.8 feet), and an average weight of roughly 104 kilograms (229 pounds). Currently, Xa'Thin body structure contains minimal amounts of muscle mass, topped with resistant scales on the surface of their bodies.
The reason for their low muscular structure derives from their scale toughness and protection. As a result from it, there has been no need for muscular or strong Xa'Thins for survival, and society. However, Xa'Thins who have pushed for muscle growth are often seen as unique, with their scales toughening up and enlarging. This is known to be their body's response to prevent separation of the scales, and eventual cracking.
The surface of these scales have a thin layer of tough material, that can resist up to 7000 kilograms per square centimeter. A rare subsection of Xa'Thin genes can allow the scales to stay optimal at 12,000 kilograms per square centimeter. The scales themselves show small amounts of pigmentation, as a result of Sa'Kia's ultraviolet bleaching of the scales. Only a select few natural Xa'Thins may be born with an innate 'sunblock', which lets them show a colorful pigmentation.
Their hard scales are not too tough internally, though. If any Xa'Thin tries to partake in a physical fist fight, they would experience sharp pain every time they would attack their opponent. This happens because Xa'Thin scales are held up and put together by strong ropes of tissue, and forcing lots of pressure in quick bursts can disrupt them. Reports of complete severing of the tissues have been recorded to happen around the eyes, arms, and chest.
The average Xa'Thin possesses about 4-8 tentacle-like features on the top of their heads. The length of these are mostly seen around 51 centimeters (1.6 feet) in length. Some of which can grow to the 60 centimeter mark (2 feet), and may require removal or shortening. Longer tentacles have also been known to not correlate to better detection of smell, which is covered next.
As a result of them having no noses, sensitive tentacles have replaced them with a grand ability to smell. This works very similarly to a nose, allowing pheromones to drift in. This data is sent to the brain, and is deciphered in a similar fashion. This has also let Xa'Thins smell many trace gases, which a Human might not detect. This includes carbon monoxide, radon, argon, helium, and nitrogen among others.
A Xa'Thin's internals are actually quite frail when compared to a Human, or any other sapient organism. This is because they lack a large muscular structure, and their delicate internal scale tissue is easy to dislodge in many cases. To counteract this, Xa'Thins systematically morphed their population's muscle structure, and tendon strength with gene editing.
Xa'Thin organs differ greatly than any Human or Ambrosian organs. For example, when compared to a Human, one would note that Xa'Thins have an extra stomach. This is the case because natural Lokiran food was very tough, until the invention of agriculture. Over the period of thousands of years, Xa'Thin organs have shifted to a point where the stomach's acid is less potent, and the lower stomach is smaller.
Xa'Thin eyes are made up of tiny light receptors, similar to an insect. The eyes also have an ability that allows Xa'Thin individuals to manipulate how far they see. This is achieved by letting Xa'Thins change the focus of their lens, and moving at until they can see close or far. particularly useful for combat, and spying. The eyes are also very fragile, and most Xa'Thins have protective covers over them.
Xa'Thins contain a large amount of bones, cartilage, and sections of muscle and trace tissues underneath their scales. The muscles act like an internal protection system, and the tendons and ligaments allow for limited flexibility, which is explained below.
Xa'Thins are usually very stiff when compared to a Human. As a result of their vast bone system, along with smaller amounts of connecting tissues, there are not a large amounts of directions that a Xa'Thin can move in. However, some notable Xa'Thins have been created with more tendon density, as well as more points for the bones to move in. These are the most flexible kinds of Xa'Thins, and they are roughly as maneuverable as a minor human athlete.
Genetically enhanced Xa'Thins are also known to be quite flexible. Some have sacrificed much of their scales toughness and rigidness to maneuver better. These Xa'Thins are also quicker and can even jump higher, as a result of less scales on their bodies.
Almost every Xa'Thin has a pronounced presence of unique abilities. Most of them are quite weak or limited due to the forces of gravity, electromagnetism, and the strong and weak nuclear forces.
Telepathy has been a staple of Xa'Thin life ever since the invention of mass cloning and genome editing. However, telepathy has been in a rare group of Xa'Thins before this technology was made. Telepathy is possible in the first place by a small neurotransmitter gland the size of a pear. This gland is located under the Xa'Thin brain near the spine. All Xa'Thins had this in some form, but they were mostly underdeveloped, being approximately the size of a walnut. They mostly functioned as more amounts of white matter, and nothing more.
However, some gifted Xa'Thins had their neurotransmitter develop much more than usual, all the way until adulthood. These had the ability to vibrate it to an ultra-high frequency. If any other Xa'Thins with this ability were nearby, they could collect and decipher the frequency with the same organ, giving way to a basic form of telekinesis. The frequency travels like sound, disturbing the air particles to send it over. Eventually, this was found out by the masses. When the rare Xa'Thins' genes were extracted, many people wanted to have their offspring hold and give this ability. Eventually, within 4 generations, almost every Xa'Thin had this ability. It soon became even more common as genome editing phased into common life.
This ability does not work in the vacuum of space, as a result of there being no medium for the frequency to travel between. Instead, people in space simply use other forms of communication.
Usually, Xa'Thins are extremely docile, and only get aggravated when pushed to a point that would make an average Human on the verge of assault. This docility has had its good and bad sides. For example, this has been unhelpful when events like The War for All happened. It had shockingly less impact on Xa'Thin opinion compared to Human opinion when it was declared. All of this docility is most likely made up from their sheer scale toughness and durability.
Xa'Thin aggravation is usually very difficult to achieve. When it happens, the Xa'Thin body is naturally pumped with testosterone/estrogen, and adrenaline. Their anger is also released in short bursts, and usually occur without warning. This may cause a Xa'Thin to do unruly acts of anger in quick successions. These snaps of anger have also been 'exploited', with Xa'Thin battle suits being given pre-built adrenaline shots. This might help soldiers on the ground, who are struggling from enemy attack.
Xa'Thins have been documented to primarily eat foods that are tough in composition, as their very acidic stomachs plow through any soft foods. Many choose to suck on foods like seeds and nuts, which have many flavors in them. Soft foods are eaten, as well, but are typically hard to enjoy as a result of a Xa'Thin's powerful jaws and teeth.
The average environment for a Xa'Thin is heavily urban-like, with only ~12% of the population living on planets that are rural. No matter the style of life that have, Xa'Thin cities are to be described as magnificent. This is because that their buildings are built with large amounts of patterns, being like polished and built with fractal-like patterns. While most buildings on Xa'Thin planets are not quite tall, there are the special 'Citadel' buildings that can go many kilometers high.
Xa'Thin last names work quite differently than any person may expect. For a start, they are scaled not on hereditary measures, but it scales of wealth and importance. This rule mostly applies to the elite, as the presidents and governors are granted the last name 'Imir. Imir in Old Xa'Thin translates to a leader or mayor. This sub-section of the rule has also been quite vague within the past few millennia. As of 200000 CE, most people have opted-in for untraditional last names.
How Xa'Thins used to be created
Many outsiders to Xa'Thainity have often pondered on how more citizens are made. Well, it does not involve a horrible and inefficient birthing process, alike humans or other mammalian or arthropod organisms. Millennia ago, before genetic cloning and even painless birthing, Xa'Thins laid large egg-like structures, which they would keep tended and incubated for approximately 3 standard months. The hatchling would then grow to be about 1/2 the mother's size and walking within only one standars year. The newborn would also molt into new scales many times, causing annoying messes. In a Xa'Thin home similar to a 21st century Earth, electronic heating and cooling for the eggs were readily available, and vaccinations would sometimes be injected inside the egg if a vulnerability was detected.
