The Treecuu Star Empire (Treecuu Common: , Treecuu-uumth-aateec) is a young, rapidly expanding star nation in Sector A1-0, approximately stretching between 500-1200 lys horizontally and 300-600 lys vertically. Commonly it is estimated that the empire comprises 31,000 star systems, of which at least 15,600 are settled to some degree. It borders the Zelvan Regime to the north-west, the Gill-Atarnië Calerost to the north, the Stoinian Star Kingdom to the south-east, Trianar to the south-west and the vast Veentu badlands to the east, as well as large regions of unexplored space. Founded in 200 BBT in the aftermath of the so-called Loo-Yee Calamities, the empire is built on the principle of subjugating neighbouring civilisations that are not capable of defending themselves in order to prevent them from maintaining interstellar spaceflight capabilities, and to enforce a Treecuu monopoly on movement and communication, with the ultimate goal of maintaining order and peace to ensure the survival of the Treecuu. The Treecuu Star Empire maintains an isolationist policy and its extensive network of buoys marking the territory claimed is well-known. However, following the Aryyt't Incident, the empire has begun seeking to establish diplomatic relations with other star nations in the sector and to gain recognition as the sovereign entity of the space it claims.

The Treecuu Star Empire has a population of about 4 trillion Treecuu, which all enjoy full citizenship, and about 2.9 trillion members of the so-called subject species (officially "protected species"), which are isolated on their respective planets of origin, barred from owning faster-than-light technology. The total number of inhabitants is significantly lower compared to most other star nations in the sector, but a successful aggressive government campaign has ensured a very high population growth rate of the Treecuu. Treecuu space is divided into thirteen mandates, each governed by a cirth (governor) who enjoys extensive personal power, being directly responsible for matters regarding law enforcement, industrial development and most importantly asserting dominance over the subject species under their control. Nominally a democracy, the empire is governed by an elected senate and a president, currently Cuul, having their seat on the planet Ecteen, the capital of the empire and Treecuu homeworld. In reality however, the empire is best described as an oligarchy, with power shifting to the Committee for the Expansion of the Empire consisting of self-appointed members, including the governors and business magnates.

The currency-less Treecuu economy is dominated by the replicator and information technology sectors, with significant contributions by the mining, shipbuilding, foodstuffs and recycling industries. Important native technology includes the space folding warp drive, quantum synthesis and ship cloaking technology. The Treecuu Star Empire has a highly developed welfare system which is also extended to the subject species. Standard of living is high among the Treecuu and generally fair to high among subject species.


The word Treecuu means "shared" in the Treecuu language. It was first used in the constitution written for the foundation of the Treecuu Republic in 291 BBT, which was also the first official document in the newly constructed language. The full name of the nation, Treecuu Star Empire, could alternatively be translated as the Star Commonwealth, but is not recommended officially.

The Treecuu nationality includes two different species that evolved on the same world - Ecteen: the Teetac insectoids and the Limavu mammalians. The insectoids where the first to develop an advanced civilisation about 220,000 BBT and dominated the planet for millennia. They colonised the Ecteen system and terraformed the neighbouring planet Cin. The insectoids were close to achieving FTL technology, however, a combination of several devastating wars, natural disasters and climate change induced a mass extinction event on Ecteen, forcing the few remaining insectoids off the home world. After a century, only a few thousand individuals on Cin had survived. They did not manage to maintain their advanced civilisation and thus reverted back to a hunter-gatherer type of civilisation. Over time, knowledge of the old world and the advanced technology diminished.

With the insectoids gone, the mammalians, which had survived the mass extinction event in small numbers in the equatorial marshlands, eventually developed an advanced civilisation. As scientific advances were made, traces of the ancient insectoid civilisation were discovered. When telescopes were aimed at the neighbouring planet they soon found it to be habitable. This prompted fast advances in astronomy and space faring technology. In 354 BBT the mammalians sent their first manned expedition to Cin, leading to first contact between the two races. It was soon established that they were genetically related and shared a common origin. Working together, the insectoids and mammalians rediscovered and reclaimed ancient Teetac artefacts and technology throughout the system. The mammalians managed to cure diseases that had plagued the insectoids for millennia. In 301 BBT they completed their first FTL flight.

Treecuu Republic

Following the peaceful integration between the insectoids and mammalians and the success of their space programme, it was decided to put their respective planets under a common government to accelerate integration and guarantee peace. The Treecuu Republic was proclaimed in 291 BBT which included the entire Ecteen system. It was a liberal democracy and the various nations on the planets had a large degree of self-governance. The same year the first deep space exploration missions were launched and warp ships were sent out to neighbouring stars. Nine years later first contact was made with the Utacians, an emerging FTL civilisation. The two civilisations maintained a relation of peace and trade. The following decades the Treecuu settled several uninhabited systems and made peaceful contact with the emerging Dacoorans and Catorans. Important breakthroughs in replication technology were made during this time. The total Treecuu population was approximately 20 billion, with a presence in 10-15 star systems.

Loo-Yee Calamities

In 240 BBT technologically advanced nomadic peoples, collectively called the Loo-Yee (in some sources called the Oleth), started visiting Treecuu space in what was likely scouting parties. Soon entire fleets arrived, who proceeded to plunder Treecuu worlds as well as neighbouring nations. After the first waves of Loo-Yee incursion, the Dacoorans hosted a conference with the goal to establish a military alliance between the Treecuu, Utacs, Dacoorans and Catorans. Except for the Catorans opting out, the treaty talks were successful. However, the Loo-Yee returned in greater numbers. The alliance was defeated defending Dacoora, which was thoroughly plundered, but never completely occupied thanks to a strong resistance movement. At the same time the isolated Catorans were almost entirely wiped out by the Loo-Yee. Seeing the fall of the two planets, the Utac negotiated a separate peace with the Loo-Yee, paying in gold and other basic resources to have the Loo-Yee leave them alone.

Utac leaving the war was seen as a great betrayal by the Treecuu, who now faced the Loo-Yee alone. After a period of both sides recovering, Treecuu and Loo-Yee forces clashed in the battle of Treel. The Treecuu deployed antimatter weapons for the first time. The outcome was a tactical draw but a strategic victory for the Treecuu, as the Loo-Yee likely decided it was too costly to continue their campaign in the region. They left and have since not been encountered again. About 70% of all Treecuu were killed in the war.

Fearing that the Loo-Yee would return, the Treecuu government approached its former allies for a renewed alliance. The Utac government declined, fearing revenge from the Loo-Yee. The Dacooran government failed to respond due to a collapse of their society following the plundering and infighting. Hardliners within the military persuaded the Treecuu government of the necessity of creating a buffer zone outside Treecuu core space for defensive purposes, and one standard year after the retreat of the Loo-Yee, a Treecuu fleet besieged Utac Prime. A special government body was formed to plan and oversee the creation of the buffer zone, called the Committee for Strategic Security (CSS). The siege lasted two years, and following escalating orbital bombardment, indiscriminately targeting military and civilian targets alike, Utac surrendered unconditionally. The CSS immediately seized Utac mines and production facilities to accelerate the construction of starships for the Treecuu Starfleet. All Utac state functions were placed under Treecuu leadership.

The following two years, under the pretence of helping the Dacooran government regain control of the planet, the Treecuu landed expeditionary forces on Dacoora Prime, which soon came under Treecuu and CSS control, suffering the same fate as Utac. Catora was also occupied, but without resistance. The CSS presented a plan to the Treecuu government on how to ensure the survival of the Treecuu and maintain order in space surrounding the Treecuu core worlds. The plan involved the subjugation of other civilisations through military expansion and a rapid increase in population by encouraging large families through extensive government support. While it was debated in the senate, news reached Ecteen of the destruction of Treecuu civilian convoys by the warring star nations Grund and Fee'ehar, causing mass protests and a popular demand for action. The government responded by voting unanimously in favour of the CSS's plan. It is uncertain if the convoys really were attacked, or if it was a false flag operation arranged by the CSS or certain members of the CSS.

The following year the CSS was reformed into the Committee for the Expansion of the Empire (CEE), being directly responsible for the planning of military expeditions and running subjugated worlds. In 200 BBT the Treecuu Star Empire was proclaimed following the annexation of Otane, home to a major spacefaring civilisation. The reform introduced the mandates (ebovanes), which are large regions of conquered and settled space directly under a governor which is appointed by the CEE.

During this period, the Treecuu economical system was fundamentally transformed due to the availability of affordable replicators and raw materials, meaning that most Treecuu could produce most basic goods they needed from home. Remaining markets offer goods that are so rare that they are not featured as transferable replicator files, or too energy-demanding for regular replicators. The Treecuu cloaking system was invented during this time, giving the Treecuu fleets an advantage over many other star nations.


After the annexation of Bicaan in the northwestern reaches of the Empire, military expansion decreased significantly due to encountering stronger and more cohesive star nations, and fearing overstretching the supply lines. The last planet in the west to be annexed was Yim-Lootuu III, also known as by its native name Aryyt't. The Aryyt't managed to send a slipspace probe with a distress call which that visited over a hundred of systems before being destroyed while jumping to a Treecuu-controlled system. The distress call was received by Drakari Celestial Imperium and the Venterran Federation which prompted the Treecuu government to attempt establishing formal relations with these star nations to learn about their attitudes about the annexations and prevent any measures to be taken to rescind the control of Aryyt't. These events led to a change in Treecuu foreign politics, shifting to a policy of seeking international recognition of claimed territory and cementing the Treecuu precense. To that end, trade agreements were made with the Ryccian Empire and extensive cooperation has been achieved with the Stoinian Star Kingdom with which there is much in common in terms of self-image and history. The Treecuu and Stoinians have signed a non-agression pact, and it is large believed that the two nations will form an alliance soon.

The CEE has further increased its power by having one of its members, Ivict, as foreign minister, gaining direct control of the Diplomatic Corps and the negotiations with other star nations. However, as the direct control of the governors and CEE is not normally felt by most Treecuu citizens, they are not aware or concerned with the elected government loosing its say in matters of controlling subject worlds or what the foreign relations should be with distant star nations.


Situated roughly in the middle of the lower half of sector A1-0, the Treecuu Star Empire lies directly west of the Veentu Badlands and spans roughly 700 ly due west, covering a centralised cross-sectional area of about 146,800 ly2. It borders the Zelvan Regime to the north-west, the Stoinian Star Kingdom to the south-east and Gill-Atarnië Calerost to the north.

About 31,000 star systems are located within Treecuu borders, of which roughly 15,600 are settled to some degree. About 50 unsettled worlds have traces of lost civilisations. The most populated systems are located towards the east. There are no known black holes in Treecuu space, but a large pulsar named Candact is located in the centre of the empire.

Administrative divisions

The Treecuu and subject species are completely segregated. On previously uninhabited worlds settled by the Treecuu, only Treecuu citizens are allowed to reside; on subjugated worlds only the natives and a limited number of Treecuu personnel necessary to maintain Treecuu control and extract resources, and their families, are allowed to reside. Therefore there are two separate tiers of administrative divisions of the Treecuu Star Empire: the system tier, which comprises all Treecuu-settled worlds and space stations, currently around 9,000, and the mandate tier, which comprises all subjugated worlds and not yet settled systems and systems with a population too small to be granted systemship. However, all systems are assigned to a mandate but they only have a subordinate role in military matters and certain aspects of interstellar communications and resource extraction. There are 13 mandates, which are further divided into subject systems.

Both the systems and subject systems can be further divided into worlds and subject worlds respectively. Worlds are typically further divided into continents and moons, while subject worlds often are allowed to arrange their own divisions.



The Senate Complex, city of Irveem, Ecteen.

The Treecuu Star Empire is nominally governed by an elected senate where each system has a specific number of seats based on its population, headed by a president. All systems have an elected local government called a System Council, which sends representatives to the Senate in the city of Irveem, Ecteen. Mandates are governed by governors appointed by the Committee for the Expansion of the Empire, which in turn appoint vice-governors for individual systems, except for the mandate capital which is directly governed by the governor. Subject worlds normally have a large degree of autonomy but have no representation in the mandate governance or the Treecuu Senate.

The self-appointed CEE has de facto control over international affairs, a majority of the military and vital industry and resources.

Elections to the system councils and the senate are held every five Ecteen years, or approximately 4.64 standard years, and all Treecuu citizens have the right to vote and run for a seat. The president is the person who manages to gain the most support in the senate, which is confirmed by a vote.

Foreign relations



The military of the Treecuu Star Empire is divided into two branches: the Planetary Forces and the and Interplanetary Forces, which themselves are divided into services that either are under the command of the Treecuu government or directly by the CEE. The Planetary Forces are divided into the Planetary Defence Forces which are under the command of the local system council or vice-governor, and the Security Forces which are de facto paramilitary forces directly commanded by the governors. The Interplanetary Forces consist of the Remote Fleets and the Mandate Fleets, which are under CEE command, the System Fleets that are under government command, and the Marine Corps that is commanded by the CEE.

The military has about 1.24 billion active personnel and 600 million reserve personnel, in total 1.84 billion, or about 0.046% of the Treecuu population. The Interplantery Forces have about 42,000 commissioned ships of at least frigate size. The military can also request civilian transport craft. Service is voluntary and only Treecuu citizens are eligible for service. Treecuu military ships and personnel participate in the Joint Exploratory Fleets.

The arsenal includes weapons of world destruction, such as antimatter devices, as well as programmable biological weapons. Treecuu ships are equipped with cloaking systems intended to help ships evade enemy sensors.

The Treecuu Star Empire has a population of about 6.9 trillion biological sapients, of which 4 trillion are Treecuu and the rest so-called subject species.

Settled worlds

The population is firmly segregated into Treecuu and subject species. There are over 19,000 worlds with an exclusively Treecuu population and an estimated 325 subject worlds populated almost exclusively by the native subject species.

Of the 19,000 settled Treecuu worlds, only 19 worlds have a population of more than ten billion, 650 worlds have a population of about 1-10 billion, and the rest are much more sparsely populated. Of the 325 subject worlds, 83 have life that evolved independently on them, while the rest were settled by the subject species before the Treecuu annexed them. Many subject planets have a much higher population than similar Treecuu planets. This is due to the ban on interstallar travel imposed on them, as well as forced relocation from other subject worlds.


Synthetic life

No synthetic/artificial life is recognised in the empire. The Treecuu government has banned the creation of synthetic sentient beings due to a fear of the so-called Tuu-Laarth ("great nullification"), the possible surpassing of synthetics, rendering biological creatures useless. Even before the reorganisation into the empire, the Senate had banned all logical machines that were more than mere computational devices. Synthetics are hunted down and destroyed on subject worlds.




The Treecuu Star Empire is a secular state but freedom of religion is granted by the constitution. The Treecuu are almost exclusively irreligious and atheist and perceive spirituality as irrational. Subject species are allowed to practice any religion. Due to the isolation imposed on subject worlds, only two religions are shared between different subject species. Hoolu is practised by sizeable minorities on both Dacoor and Utac, and has a smattering of Treecuu followers. Preoylob has followers on serval moons in the Laree and Baac systems.

There are several examples of less advanced civilisations where the Treecuu are revered as divine. On Yuu-caan, home to the hunter-gatherer Ceecs, the Treecuu are widely believed to be gods due to their superior technology appearing to be manifestations of magic powers. Treecuu authorities generally take advantage of this to control these civilisations.



Healthcare in the Treecuu Star Empire is universal for all citizens. It is considered to be of excellent quality and contributes greatly to the extreme growth rate of the Treecuu. Healthcare authorities claim to have eradicated or cured all known viral and bacterial infections. The Treecuu government funds and supports the healthcare on subject worlds and the Treecuu has devised cures for many severe diseases. However, Treecuu autorites have also deliberately spread disease in societies as a means of imposing control, or in some instances as a propaganda ploy where the disease has been rapidly eradicated to show the superiority of Treecuu technology and the benevolence of the Treecuu.
