The Th'ega are the dominant species of the planet Kavla. They are some of the only mammals on the planet. They are remarkably humanoid, with the biggest differences being that they have gills on their neck and their skin is normally a pale blue. They live in "iceberg" cities spread across the planet. The cities have been given this nickname by humanity due to the cities extending far below the surface, similar to icebergs. The planet is controlled by the Th'ega Federation, which also controls a few nearby worlds. The Th'ega live in a democracy where every 4 Kavlan years (just over one Standard year), two citizens are chosen in each city to represent them in the Federal Parliament in the Federation's capital city, Li'ion (li-EE-on).
The Th'ega are roughly humanoid, with gills on their necks. Average height among Th'ega is 1.8 metres for both sexes. Most of them have pale blue skin (developed as camouflage in the shallower waters), though some have darker blue skin or even purple. Most Th'ega live for around 170 standard years (590 Kavlan years), though this is being extended by gene editing research. It is thought the Th'ega evolved on the old supercontinent on early Kavla. When the planet flooded, the early Th'ega adapted by evolving gills and bluer skin. They also developed the fins along their forearms at that time.Modern Th'ega are still able to breathe above water, though it's thought this trait may be lost in a few million years.
The Th'ega are a very peaceful species and are very welcoming to strangers. There is a planet-wide, religion called Procha (pro-CK-ah). The religion is thought to be based off an older religion that dates back as far as the time of the First Civilisation's First Era, when the early Th'ega were still in the hunter-gatherer stage. It is theorised that the First Civilisation visited the early hunter-gatherers but, for some unknown reason, decided to not to terraform the world or move any Th'ega to another world. This visit may have kickstarted the Kavlan religion. To this day, Procha followers worship a collection of gods, the most notable being Ochi'an; "God of the Stars". The star Kavla orbits was named after this god early in Th'ega history. Another god is Kavla'an which translates to "God of the earth" or "God of Kavla".
The Th'ega prefer to disrupt their natural environments as little as possible, as they believe it upsets Kavla'an. They try to cause as little light pollution as possible and are incredibly conservative with their use of natural resources. The species as a whole is known to be very friendly and welcoming to strangers. This trait meant that their have been almost no major conflicts between Th'egan cities or colonies. The Prochans believe war is an absolute last resort, and can only be initiated if all other diplomatic options are completely exhausted. Even then, war is frowned upon and often leads to the individual(s) who started the war being removed from office. They then are prosecuted in Kavlan High Court in Li'ion's upper layer. Depending on the size of the conflict and the number of people killed, the politicians can be sentenced to anything from 3 Kavlan years in prison to a life sentence. Because of this, most wars last no longer than 3 Standard months.
The first life on Kavla first evolved only one million years after its formation (Kavla formed approximately 679 million years ago). Three hundred million years ago, the first ancestors of the Th'ega emerged on Kavla's supercontinent, Il'cha (il-CK-ah). 50 million years later, the planet flooded after several asteroids carrying large amounts of water impacted the planet. At the same time, the first actual Th'ega appeared. It appears that life on Kavla seems to evolve incredibly slowly for an unknown reason. Around the time of the First Civilisation's First Era, the Th'ega became hunter-gatherers.
Five million years ago, the Th'ega hit their equivalent of the industrial revolution. They stayed in a state similar to late 20th century to early 21st century Earth up until 198,378 CE. This is when they hit the Singularity and began to rapidly increase in population. Only a decade later, the first warp drive was built. This technology was used to form outposts on Eredon and on the moons of Aeris'ti, the closest planet to Kavla. Aeris'ti itself is a gas giant, and several politicians have proposed floating cities similar to those of Jupiter and Saturn, though the project would cost an estimated 15 billion Chrani (the local currency in the Orchi'an system). Oddly enough, the Th'ega colonies in Kari'an (the other star in Orchi'an's binary system) use a different currency called Ikrani
Just after the singularity on Kavla, the Th'ega made first contact with the Confederacy of Humanity and discovered the numerous empires that reside in the Laniakea Supercluster. Soon after this discovery, the Th'ega re-organised their political structure into the Th'ega Federation.
The planets of the Th'ega were raided by The Aldorian Assembly of Clans, bringing some of the members of this species across the Universe to other nations.
The Th'ega have recently made huge technological strides thanks to their singularity. They have developed a prototype warp drive that is capable of exploring any system within 10 light years, though it has only been used to explore their neighbouring systems so far. The Th'ega Federation are currently aiming to colonise at least one planet outside their native binary system by 200,100 CE. Most of the Federation's budget is being directed to genetic modification. Currently, the Federation aim to stop all known diseases on Kavla through gene editing, then they plan on increasing the Th'ega's lifespan to 210 standard years (730 Kavlan years). The end goal of the project is to make Th'ega immortal.
AI research takes up a large amount of the Technology Division's (the branch of the Federation that works on creating and testing new technologies) budget. In 199,320 CE, the first self-aware AI was created. It still is operational in 200,000 CE and has even been granted Th'ega Citizenship and the Federation's equivalent of Human Rights. This AI named itself Yu'in (yo-EE-un), the Kail word for "First person" or "First being". Yu'in is known to have a sense of humour and likes to print avatars for itself so it can visit Kavla's ocean cities in person. It is currently working with researchers to create more intelligences like itself.
