Hemisu is a terrestrial planet located in the Outer Band of the Talin Galaxy. It orbits the orange dwarf star, Hoku. It has three small moons that orbit it. Hemisu offers many biomes such as plains, forests, savannahs, deserts, barren mountains/plateaus, and a vast freshwater ocean. It is comprised of one massive supercontinent and superocean, with one side of the planet being almost entirely land and the other water, with a few major cities and spaceports. It is home to a multitude of animals and plant life. The sentient native species are the Nemeans, lion-like humanoids named after the Nemean lion from Constantian mythology. The planet and its moons are also home to a sizable population of humans, who first settled there in 356 BHT.

Hemisu and its moons are rich in a rare metal ore called etherium that when refined is used in almost everything by the humans that mine it. As such, the surface of Hemisu and its moons are covered in mines and drilling facilities. Due to the many practical uses of refined etherium, it is the most lucrative trade commodity on the planet, and as such is heavily regulated and protected.

Etymology

Hemisu, from the Constanti “hēmisys”, which translates to “half” (temporal and spatial). The humans that settled here named it in reference to Plato’s use of the word for half ἥμισυ (hemisu) much as English refers to one's other half as a partner, but instead referring to the two halves of the planet being a supercontinent and superocean.

Physical characteristics

Size and shape

Hemisu has a rounded shape, through hydrostatic equilibrium, with an average diameter of 12,742 kilometres (7,918 mi), making it the largest planetary sized and largest terrestrial object of the Hoku Solar System, as it is the only planet orbiting Hoku.

Due to Hemisu's rotation it has the shape of an ellipsoid, bulging at its Equator; its diameter is 43 kilometres (27 mi) longer there than at its poles. Hemisu's shape also has local topographic variations. Parallel to the rigid land topography the ocean exhibits a more dynamic topography.

Internal structure

Hemisu's surface is the boundary between the atmosphere, and the solid earth and ocean. Defined in this way, it has an area of about 510 million km2 (197 million sq mi). Hemisu can be divided into two hemispheres: by latitude into the polar Northern and Southern hemispheres; or by longitude into the continental Eastern and Western hemispheres.

Hemisu's ocean covers 47%, or 121,703,421.31 km2 (75,623,000 sq mi) of Hemisu's surface. This vast pool of freshwater is known as the Great Ocean, and makes Hemisu with its dynamic hydrosphere a water world or ocean world. Indeed, in Hemisu's early history the ocean may have covered it completely. The ocean covers Hemisu's oceanic crust, with the shelf seas covering the shelves of the continental crust to a lesser extent. The oceanic crust forms large oceanic basins with features like abyssal plains, seamounts, submarine volcanoes, oceanic trenches, submarine canyons, oceanic plateaus, and a globe-spanning mid-ocean ridge system.

Just over half of Hemisu's surface is land: 53% or 167,946,311.808 km2 (104,357,000 sq mi). The land surface includes many islands around the globe, but most of the land surface is taken by the supercontinental landmass. The terrain of the land surface varies greatly and consists of mountains, deserts, plains, plateaus, and other landforms.

Land can be covered by surface water, snow, ice, artificial structures or vegetation. Most of Hemisu's land hosts vegetation.

The pedosphere is the outermost layer of Hemisu's land surface and is composed of soil and subject to soil formation processes. Soil is crucial for land to be arable. Hemisu's total arable land is 10.7% of the land surface, with 3.3% being permanent cropland. Hemisu has an estimated 16.7 million km2 (6.4 million sq mi) of cropland and 33.5 million km2 (12.9 million sq mi) of pastureland.

The land surface and the ocean floor form the top of Hemisu's crust, which together with parts of the upper mantle form Hemisu's lithosphere. Hemisu's crust may be divided into oceanic and continental crust. Beneath the ocean-floor sediments, the oceanic crust is predominantly basaltic, while the continental crust may include lower density materials such as granite, sediments and metamorphic rocks, as well as an abundance of etherium. Nearly 75% of the continental surfaces are covered by sedimentary rocks, although they form about 5% of the mass of the crust.

Hemisu's surface topography comprises both the topography of the ocean surface, and the shape of Hemisu's land surface. The submarine terrain of the ocean floor has an average bathymetric depth of 6 km, and is as varied as the terrain above sea level. Hemisu's surface is continually being shaped by internal plate tectonic processes including earthquakes and volcanism; by weathering and erosion driven by ice, water, wind and temperature; and by biological processes including the growth and decomposition of biomass into soil.

Satellite system

The three moons of Hemisu are Ether 1, 2, and 3, named due to the abundance of etherium ore on all three. They are irregular in shape and relatively small. Ether 1 is the largest. Its mass is 1.2% that of the Hemisu, and its diameter is 3,474 km (2,159 mi), roughly one-quarter of Hemisu's. Ether 1 orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Hemisu. Tidal forces between Hemisu and Ether 1 have synchronized the its orbital period (lunar month) with its rotation period (lunar day) at 29.5 Hemisu days, causing the same side of Ether 1 to always face Hemisu. Ether 1's gravitational pull—and, to a lesser extent, Hoku's—are the main drivers of Hemisu's tides. Compared to Ether 1, Ether 2 and 3 are significantly smaller than Ether 1; Ether 2 has a diameter of 22.2 km (13.8 mi) and a mass of 1.08×1016 kg, while Deimos measures 12.6 km (7.8 mi) across, with a mass of 1.5×1015 kg. They both orbit around one another while also orbiting around Hemisu. Ether 2 orbits with a semi-major axis of 9,377 km (5,827 mi) and an orbital period of 7.66 hours; while Ether 3 orbits farther with a semi-major axis of 23,460 km (14,580 mi) and an orbital period of 30.35 hours.

Two major hypotheses have emerged as to the origin of the moons: The first suggests that they originated from Hemisu itself, perhaps from a giant impact event. The second suggests that the two smaller moons are captured asteroids. Both hypotheses are compatible with current data, though upcoming sample return missions may be able to distinguish which hypothesis is correct.

Atmosphere

The atmospheric pressure at Hemisu's sea level averages 101.325 kPa (14.696 psi), with a scale height of about 8.5 km (5.3 mi). A dry atmosphere is composed of 56.084% nitrogen, 18.946% oxygen, 10.013% carbon dioxide, 10.934% argon, and trace amounts of other gaseous molecules. Due to the oxygen being less than 19.5% and an increased amount of carbon dioxide and argon in the atmosphere, humans live inside structures with ideal atmospheric conditions as well as must wear specialized suits when traversing Hemisu's natural environment. Water vapor content varies between 1% and 4% but averages about 2.5%. Clouds cover around two-thirds of Hemisu's surface, more so over ocean than land. The height of the troposphere varies with latitude, ranging between 8 km (5 mi) at the poles to 17 km (11 mi) at the equator, with some variation resulting from weather and seasonal factors.

Hemisu's biosphere has significantly altered its atmosphere. The ozone layer blocks ultraviolet solar radiation, permitting life on land. Other atmospheric functions important to life include transporting water vapor, providing useful gases, causing small meteors to burn up before they strike the surface, and moderating temperature. This last phenomenon is the greenhouse effect: trace molecules within the atmosphere serve to capture thermal energy emitted from the surface, thereby raising the average temperature. Water vapor, carbon dioxide, methane, nitrous oxide, and ozone are the primary greenhouse gases in the atmosphere.

Weather and climate

Hemisu's atmosphere has no definite boundary, gradually becoming thinner and fading into outer space. Three-quarters of the atmosphere's mass is contained within the first 11 km (6.8 mi) of the surface; this lowest layer is called the troposphere. Energy from the star Hoku heats this layer, and the surface below, causing expansion of the air. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.

The primary atmospheric circulation bands consist of the trade winds in the equatorial region below 30° latitude and the westerlies in the mid-latitudes between 30° and 60°. Ocean heat content and currents are also important factors in determining climate, particularly the thermohaline circulation that distributes thermal energy from the equatorial regions to the polar regions.

Hemisu receives 1361 W/m2 of solar irradiance. The amount of solar energy that reaches Hemisu's surface decreases with increasing latitude. At higher latitudes, the sunlight reaches the surface at lower angles, and it must pass through thicker columns of the atmosphere. As a result, the mean annual air temperature at sea level decreases by about 0.4 °C (0.7 °F) per degree of latitude from the equator. Hemisu's surface can be subdivided into specific latitudinal belts of approximately homogeneous climate. Ranging from the equator to the polar regions, these are the tropical (or equatorial), subtropical, and temperate climates.

Further factors that affect a location's climates are its proximity to the ocean, the oceanic and atmospheric circulation, and topology. Places close to the ocean typically have colder summers and warmer winters, due to the fact that the ocean can store large amounts of heat. The wind transports the cold or the heat of the ocean to the land. Atmospheric circulation also plays an important role.

Water vapor generated through surface evaporation is transported by circulatory patterns in the atmosphere. When atmospheric conditions permit an uplift of warm, humid air, this water condenses and falls to the surface as precipitation. Most of the water is then transported to lower elevations by river systems and usually returned to the ocean or deposited into lakes. This water cycle is a vital mechanism for supporting life on land and is a primary factor in the erosion of surface features over geological periods. Precipitation patterns vary widely, ranging from several meters of water per year to less than a millimeter. Atmospheric circulation, topographic features, and temperature differences determine the average precipitation that falls in each region.

Fauna and flora

Native fauna

The dominant sentient species of Hemisu are the Nemeans, anthropomorphic lions that inhabit various regions of the supercontinent. Renowned for their strength and adaptability, Nemeans thrive in diverse habitats ranging from forested regions to arid deserts. Their connection with the environment is reflected in their traditional practices, which emphasize sustainability and coexistence with nature.

The planet's non-sentient fauna consists of a multitude of unique creatures adapted to its varied biomes. In the savannahs, large herbivores such as horned megabeasts and swift, gazelle-like creatures graze on the plentiful grasses, while predators like the razor-clawed drakons dominate the food chain. The dense forests are home to arboreal species, including brightly colored avian species with bioluminescent plumage, and agile primate-like mammals known for their complex social structures. Deserts host resilient life forms such as burrowing reptilian creatures and drought-tolerant insect colonies, while the freshwater Great Ocean teems with marine life, including immense leviathan-like creatures and schools of bioluminescent fish.

Native flora

Hemisu’s plant life is equally diverse, with vast grasslands, towering forests, and hardy desert vegetation forming the backbone of its ecosystems. The savannahs are characterized by sprawling fields of tall, golden grass punctuated by hardy, drought-resistant trees. Forests are rich with towering canopy trees that harbor epiphytes and vine networks, while the undergrowth thrives with ferns and flowering plants. The deserts are dominated by succulents and hardy shrubs capable of storing water and withstanding extreme temperatures.

The most distinctive flora of Hemisu are the etherium-absorbing plants found near mining areas. These plants, known as Etherflora, exhibit unusual metallic hues in their foliage, believed to be adaptations for metabolizing trace amounts of etherium from the soil. Their bioluminescent flowers attract pollinators, creating vibrant oases even in barren regions.

Human-introduced species

The arrival of humans on Hemisu brought additional complexity to the planet’s ecosystems. Livestock species, such as cattle and sheep, were introduced for agriculture, alongside crops adapted for Hemisu’s arable land. Over time, these species integrated with the native environment, often altering local ecosystems. For example, human-introduced pollinators like bees now coexist with native species, facilitating cross-pollination of native and non-native flora.

Conservation and challenges

The heavy mining of etherium and expansion of human settlements have led to significant ecological impacts, including habitat fragmentation and pollution. Nemean conservationists and human environmental scientists have collaborated to establish protected areas and rehabilitation programs to preserve Hemisu’s biodiversity. These efforts include reforestation projects, the creation of wildlife corridors, and the regulation of mining activities to minimize environmental damage. They have been met with heavy opposition due to the fact that etherium is the number one trade commodity in the economy of Hemisu.

History

Pre-human history

Geological formation and early development

Hemisu began its formation approximately 4.6 billion years ago, shaped by accretion within the protoplanetary disk surrounding the star Hoku. Its unique configuration, with one side dominated by a massive supercontinent and the other by the vast Great Ocean, likely emerged from a combination of tectonic and volcanic activities. The supercontinent formed as tectonic plates converged, while the ocean’s basin developed from divergent plate movements. Early geological surveys indicate that Hemisu’s crust, both continental and oceanic, was rich in etherium, a rare and highly conductive metal that has played a critical role in the planet’s later history.

The early ocean-covered surface underwent a dramatic transformation over millions of years. Hemisu’s Great Ocean initially dominated the planet’s surface, but the gradual emergence of landmasses led to the current supercontinent configuration. This dynamic hydrosphere likely contributed to the erosion, sediment deposition, and mineral distribution that shaped Hemisu’s distinctive topography.

Development of biomes and atmosphere

Hemisu’s atmosphere initially consisted primarily of carbon dioxide, nitrogen, and trace amounts of other gases. Over time, volcanic outgassing and the advent of photosynthetic organisms altered the composition, increasing oxygen levels and paving the way for complex life. The gradual formation of an ozone layer protected the surface from harmful ultraviolet radiation, fostering diverse ecosystems across the supercontinent and ocean.

Distinct biomes began to emerge, driven by tectonic shifts, atmospheric circulation, and climatic variations. The supercontinent hosted a range of environments—from arid deserts and expansive savannahs to lush forests and barren mountains. The Great Ocean, with its immense depth and dynamic currents, developed unique marine ecosystems, including coral-like structures that hosted vibrant underwater communities.

Evolution of native life

The evolutionary timeline of Hemisu spans billions of years, resulting in an intricate web of life adapted to the planet’s diverse conditions. Early microbial life forms thrived in oceanic hydrothermal vents, where etherium deposits provided unique chemical interactions that may have accelerated biochemical evolution. These microbes eventually gave rise to more complex organisms, including aquatic plants and primitive invertebrates.

Life on land began with the colonization of coastal areas by plant species, which expanded into interior regions, forming vast forests and grasslands. Hemisu’s diverse fauna evolved in tandem, shaped by the varied biomes of the supercontinent. Key evolutionary milestones include the emergence of the Nemeans, the planet’s dominant sentient species, and the development of apex predators like razor-clawed drakons and megafauna like horned beasts.

Emergence of the nemeans

The Nemeans, anthropomorphic lion-like beings, are the culmination of millions of years of evolution. Adapted to Hemisu’s varied climates, they display exceptional physical resilience and intelligence. Fossil records and genetic studies suggest the Nemeans originated in the savannah regions, where competition for resources drove the development of their social structures, tool use, and eventually, complex cultural systems.

Early Nemean societies were primarily nomadic, relying on hunting, gathering, and small-scale agriculture. As they advanced, they established permanent settlements and developed sustainable practices that harmonized with their environment. Nemean culture placed significant emphasis on coexistence with nature, reflected in their spiritual beliefs and governance systems.

Early etherium interaction

Etherium, abundant in Hemisu’s crust, played a pivotal role in shaping its pre-human history. Nemeans discovered etherium deposits through natural erosion and volcanic activity. Initially used for decorative purposes due to its metallic sheen and malleability, etherium’s properties were eventually harnessed for practical applications, including tools and rudimentary energy storage devices. Archaeological evidence points to etherium’s central role in Nemean technological and cultural development.

Pre-Human civilizational advances

By the time of human arrival in 356 BHT, Nemean civilizations were in the early stages of their Iron Age. They had begun forging tools and weapons from iron, though their techniques were relatively rudimentary compared to later human advancements. Small-scale agricultural practices and hunting remained integral to their way of life, supplemented by limited trade networks between tribes and clans across the supercontinent.

While the Nemeans had established permanent settlements and experimented with basic metallurgical techniques, they had yet to achieve widespread urbanization or industrialization. Their societies were deeply connected to nature, and their cultural practices emphasized balance and sustainability. These foundations provided a unique backdrop for the arrival of humans, who introduced advanced technology and mining practices to the planet.

Human settlement

Initial contact

The arrival of human settlers in 356 BHT marked a pivotal moment in the history of Hemisu. Humans, driven by the promise of exploration and resources, began establishing settlements along the supercontinent's coastlines and plains. Initial contact between humans and Nemeans was limited and largely peaceful. The Nemeans, accustomed to harmonious living and respectful of their environment, viewed the humans with curiosity rather than hostility. Likewise, humans, awed by the Nemeans' physical and cultural sophistication, sought to learn from and coexist with them.

During this period of early interaction, humans and Nemeans engaged in occasional trade, exchanging tools, knowledge, and cultural artifacts. The Nemeans shared their deep understanding of Hemisu’s ecosystems and sustainable practices, while humans introduced advanced technologies and new agricultural methods. Despite the mutual benefits of these exchanges, the two species largely kept to their own communities, with minimal integration.

Discovery of etherium deposits

The fragile balance between humans and Nemeans began to shift when human explorers discovered vast etherium deposits near many Nemean homelands. Etherium, already prized by the Nemeans for its cultural and practical value, held immense potential for human technology, particularly in energy generation and advanced electronics. This discovery sparked a fervent rush among human settlers and off-world corporations eager to exploit the resource.

As mining operations expanded, tensions escalated. Many of the richest etherium veins lay beneath lands sacred to the Nemeans or integral to their way of life. Initial negotiations for access to these deposits often broke down, with human settlers offering terms that disregarded Nemean cultural values and territorial claims. The Nemeans resisted encroachment, leading to skirmishes and localized conflicts. Despite their strength and resilience, the Nemeans were unprepared for the humans’ advanced weaponry and military tactics.

Nemean war

The conflict over etherium escalated into a full-scale war. Human forces, backed by corporate interests, launched coordinated campaigns to secure mining rights and suppress Nemean resistance. Entire Nemean communities were displaced, their lands seized and their sacred sites desecrated. Over time, the Nemean population dwindled due to warfare, forced relocations, and the destruction of their natural habitats.

By the height of the conflict, many surviving Nemeans were captured and enslaved, forced to work in etherium mines or perform other labor under harsh conditions. The once-thriving Nemean civilization was reduced to a shadow of its former self, its cultural heritage suppressed and its people marginalized.

Nemean revolution

Decades of oppression bred a simmering resentment among the Nemeans, which eventually culminated in a coordinated revolution. Sparked by a charismatic Nemean leader, Ajani, and supported by sympathetic human activists, the rebellion spread across Hemisu. Utilizing guerrilla tactics, sabotage, and their intimate knowledge of the terrain, the Nemeans gradually reclaimed their autonomy. The revolution gained momentum as public opinion among humans began to shift, with many settlers opposing the corporations’ exploitation of both etherium and the Nemeans.

After years of conflict, a treaty was signed, marking the end of the revolution. The Nemeans’ freedom was restored, and their lands were returned to them where possible. Corporations were forced to scale back their operations and adopt stricter regulations regarding etherium mining. The treaty also established frameworks for interspecies governance, aimed at fostering cooperation and preventing future conflicts.

The era of peace

The post-revolution era on Hemisu is characterized by a fragile but enduring peace between humans and Nemeans. Joint councils were established to mediate disputes and oversee shared resources, including etherium. Both species worked to rebuild trust and promote cultural exchange, though deep scars from the conflict remained.

The Nemeans began revitalizing their cultural traditions and restoring their damaged ecosystems. Human settlers, now more attuned to the principles of sustainability, adopted practices that aligned more closely with Nemean values. Collaborative projects, such as reforestation initiatives and shared educational institutions, became symbols of the new partnership.

Despite these efforts, challenges persisted. Economic disparities, lingering prejudices, and occasional flare-ups of tension continued to test the peace. However, both humans and Nemeans remained committed to coexistence, recognizing that their shared future depended on mutual respect and understanding.

Modern day

Post-revolution and rebuilding (120 AHT - 200 AHT)

The peace treaty signed in 120 AHT brought an end to centuries of conflict between humans and Nemeans, marking the beginning of a new era for Hemisu. The agreement established shared governance councils and demarcated regions for both humans and Nemeans to ensure fair distribution of resources and autonomy. For the first time in centuries, Nemeans began rebuilding their population and cultural institutions, while human society sought to heal from the moral and economic consequences of the Etherium Wars and the Nemean enslavement.

The initial decades of peace were marked by cautious optimism. Trade between human and Nemean communities flourished, with Nemeans providing expertise in sustainable agricultural practices and humans offering advanced technological tools. A cooperative effort to restore the natural environment, scarred by years of etherium exploitation, became a symbol of mutual commitment to the planet’s well-being.

Era of shared prosperity (200 AHT - 550 AHT)

By the mid-200s AHT, Hemisu experienced a golden age of cultural and economic growth. Joint research initiatives between human and Nemean scholars led to significant breakthroughs in etherium energy systems. These advancements allowed for clean, renewable energy without further exploitation of the dwindling deposits. Cultural exchanges also deepened, as humans adopted aspects of Nemean spirituality and Nemeans integrated certain human technological innovations into their daily lives.

The Council of Hemisu, a bicameral governance body, was established to represent both species equally in planetary decision-making. This body became a model of cooperation, navigating disputes and overseeing development projects with remarkable success. Infrastructure projects, including interspecies cities, emerged as shining examples of collaboration, blending human technological prowess with Nemean ecological harmony.

Rise of etherium nationalism (550 AHT - 720 AHT)

Despite the progress, underlying tensions began to reemerge. By 550 AHT, technological advancements and increased demand for off-planet exports rekindled interest in Hemisu’s etherium deposits. A new group of humans, identifying as Etherium Nationalists, argued for the reclamation of old mines located in historically Nemean territories. They believed these resources were critical for maintaining Hemisu’s technological edge in the Talin Galaxy and securing economic dominance.

The movement gained traction among certain human industrial leaders and political figures, including prominent members of the Council of Hemisu. These individuals claimed that modern mining techniques would minimize environmental damage and insisted that compensation would be provided to the Nemeans. However, the proposal sparked outrage among the Nemean population, who saw it as a violation of the peace agreement and a return to the exploitative practices of the past.

Nemean resistance and human divisions (720 AHT - 1760 AHT)

By 1760 AHT, tensions had escalated into widespread protests. Nemean leaders warned that any attempt to reclaim the mines would lead to catastrophic consequences for the fragile peace. Grassroots resistance movements formed across Nemean territories, emphasizing the spiritual significance of the land and the devastation caused by past mining operations.

The human population itself was deeply divided. While Etherium Nationalists pushed for industrial expansion, other factions, including human environmentalists and interspecies advocates, stood firmly with the Nemeans. This ideological split culminated in heated debates within the Council of Hemisu, where gridlock prevented any decisive action for over a millenia.

The hemisu accords

In 1760 AHT, a violent standoff at the site of an old etherium mine brought the planet to the brink of another war. The incident, in which human industrialists attempted to force their way into Nemean lands, resulted in casualties on both sides. The event shocked the population and led to renewed calls for reconciliation.

A summit convened in the capital city of Lioris], involving human and Nemean leaders as well as neutral mediators from neighboring planets. The result was the Hemisu Accord, a landmark agreement that reinforced the sanctity of Nemean lands and banned further etherium mining without mutual consent. The Accord also established an independent body, the Hemisu Preservation Committee (HPC), to monitor and enforce the agreement, ensuring accountability.

Contemporary hemisu (1760 AHT - Present)

In the modern era, Hemisu remains a planet of both hope and tension. While the Hemisu Accord has maintained relative peace, the scars of past conflicts linger. The Etherium Nationalist movement persists on the fringes of human society, occasionally sparking debates about resource allocation and economic priorities. Meanwhile, Nemeans have focused on cultural revival, using their influence within the HPC to safeguard their ancestral lands.

Joint human-Nemean initiatives continue to thrive in areas like renewable energy, off-planet diplomacy, and scientific exploration. However, the issue of etherium remains a delicate subject, with both species recognizing its potential to reignite old animosities.

Hemisu’s modern history is a testament to the challenges of coexistence and the resilience of its inhabitants. While the future remains uncertain, the shared commitment to peace and sustainability offers a path forward for both humans and Nemeans in the ever-changing landscape of the Talin Galaxy.

Culture

Language and communication

The blending of languages was one of the first signs of cultural integration. Hemisan emerged as a lingua franca, combining elements of Nemean syntax with human linguistic structures. Over time, it became the primary language used in urban centers, trade hubs, and joint governance forums.

Art and architecture

Artistic styles from both humans and Nemeans merged, resulting in vibrant and intricate forms of expression. Public spaces often feature murals depicting the shared history of the two species, blending human realism with Nemean symbolic motifs. Architecture in major cities integrates Nemean emphasis on natural harmony with human engineering innovations, creating structures that are both functional and aesthetically pleasing.

Festivals and rituals

Several joint festivals commemorate significant events, such as the Day of Accord, which celebrates the signing of the peace treaty. This day is marked by parades, performances, and shared meals featuring cuisines from both cultures. Religious and spiritual practices have also seen some convergence, with humans and Nemeans jointly honoring figures or ideals that symbolize unity and reconciliation.

Education and philosophy

Institutions of learning on Hemisu now promote a combined curriculum that emphasizes the strengths and histories of both species. The integration of Nemean environmental philosophy with human scientific inquiry has inspired new approaches to sustainable living and technological innovation.

Inhabitants

Nemeans

The Nemean culture, deeply rooted in their ancient traditions, remains centered on their connection to Hemisu’s natural world. Despite the challenges they faced during and after the conflict, the Nemeans have preserved much of their identity and adapted it to coexist with human influence.

Nemean spirituality is intricately tied to the land and etherium, which they consider sacred. They believe in the concept of “Ki’tarra,” a balance between all living things and the planet’s resources. This philosophy influences their governance, which prioritizes communal well-being and environmental stewardship.

Traditional Nemean society is clan-based, with leadership roles often decided through consensus rather than hierarchy. While the peace treaty necessitated the adoption of more structured governance for interspecies collaboration, many Nemeans still look to their clan leaders for guidance on cultural matters.

Nemean art is highly symbolic, often depicting their myths, ancestors, and the natural world. Storytelling is a revered tradition, with oral histories passed down through generations. These stories have started to incorporate shared narratives with humans, highlighting themes of resilience and unity.

Humans

Human culture on Hemisu retains many traits brought from their origin worlds while also adapting to the unique conditions of their adopted planet. Humans are known for their technological ingenuity, and their culture remains heavily influenced by their industrial and colonial history.

Human society continues to prioritize innovation, particularly in fields such as etherium-based technology, space exploration, and renewable energy. Despite earlier conflicts, many humans today are committed to developing technologies that minimize environmental impact and foster coexistence with Nemeans.

Politics and government

Banner of the Council of Hemisu

Founding principles

The Council of Hemisu was established following the Hemisian Accord, the treaty that ended the prolonged conflict between humans and Nemeans. The Council was designed as a governing body that would ensure representation, fairness, and collaboration between the two species. Its charter is founded on three core principles:

• Equality: Both humans and Nemeans are granted equal representation and rights under Hemisian law.
• Sustainability: Governance must prioritize the preservation of Hemisu’s ecosystems and etherium resources.
• Peaceful Coexistence: Decisions must promote mutual respect and cooperation between the two species.

Composition

The Council is a bicameral body consisting of two chambers: the Chamber of Delegates and the High Council.

1. Chamber of Delegates:

• Comprised of representatives elected by regional constituencies, with humans and Nemeans having proportional representation based on population.
• Delegates serve five-year terms and focus on local issues, legislative proposals, and budget allocations.

2. High Council:

• Made up of twelve members: six humans and six Nemeans, selected through a combination of election and appointment to ensure a balance of expertise and regional representation.
• Oversees long-term strategies, interspecies relations, and critical resource management, especially concerning etherium reserves.

Decision-making process

The Council operates under a dual-consensus model:

1. Chamber of Delegates:

• Proposes and debates legislation. For a bill to proceed, it requires a simple majority vote.
• If a proposed law involves interspecies relations or etherium management, it must also pass a secondary vote ensuring majority approval from both human and Nemean delegates.

2. High Council:

• Reviews and ratifies legislation passed by the Chamber of Delegates.
• For significant decisions (e.g., mining permissions, ecological preservation measures), a supermajority (at least nine out of twelve members) is required.

Administrative functions

The Council oversees several agencies and departments:

1. Environmental Preservation Bureau (EPB):

• Monitors and enforces regulations to protect Hemisu’s ecosystems.
• Works with local communities to promote sustainable practices.

2. Etherium Resource Authority (ERA):

• Regulates mining, trade, and usage of etherium to prevent overexploitation.
• Collaborates with scientists and engineers to develop alternative technologies.

3. Cultural Integration Office (CIO):

• Promotes shared cultural events, language programs, and historical preservation.
• Mediates interspecies disputes at the community level.

4. Defense and Security Directorate (DSD):

• Maintains peacekeeping forces, composed equally of human and Nemean personnel.
• Focuses on preventing interspecies violence and external threats.

Current challenges

Despite its ideals, the Council faces several challenges:

1. Resource Conflicts:

• A faction of humans, including prominent industrial leaders, is lobbying to reclaim etherium mines located in Nemean territories. This has reignited tensions and created legislative gridlocks.

2. Representation Disparities:

• Some regions claim that the proportional representation system does not fully address local issues, especially in remote Nemean communities.

3. Cultural Divide:

• While shared cultural initiatives have been successful, deep-seated prejudices remain in some sectors of both societies, occasionally manifesting in discriminatory practices.

4. Environmental Pressures:

• Hemisu’s ecosystems are under strain due to industrial activities and climate shifts, requiring urgent and innovative solutions.

Future prospects

The Council of Hemisu represents a unique experiment in interspecies governance. Its success relies on the continued commitment to collaboration, transparency, and adaptability. Ongoing dialogues and cultural exchanges are seen as pivotal to fostering trust and ensuring a harmonious future for both humans and Nemeans on Hemisu.

Economy

Etherium, the rare and highly conductive metal found abundantly in Hemisu’s crust, is the cornerstone of the planet’s economy. Its unique properties, including superconductivity at room temperature and the ability to store vast amounts of energy with minimal loss, make it an irreplaceable resource for technological, industrial, and energy-related applications. This has positioned Hemisu as a critical player in the interstellar market, driving both prosperity and conflict throughout its history.

Key sectors of the etherium-based economy

1. Mining and Refinement: Etherium mining remains one of the most significant industries on Hemisu. Large-scale operations are concentrated in regions where rich deposits are located, including the Nemean territories. The extraction process involves sophisticated machinery capable of preserving the purity of etherium while minimizing environmental damage. Refined etherium is processed in specialized facilities to meet the exacting standards required for its various applications.

2. Energy Production: Etherium is the primary resource for energy production on Hemisu. Specialized reactors harness its potential to generate clean, nearly limitless power for both domestic use and export. These reactors form the backbone of the planet’s infrastructure, powering cities, industries, and transportation systems.

3. Technology and Manufacturing: The properties of etherium have spurred innovation across various technological sectors. Advanced electronics, aerospace components, and medical devices rely on etherium’s superconductive and energy-storing capacities. Hemisu’s manufacturing hubs are renowned for producing cutting-edge technologies that are highly sought after across the galaxy.

4. Interstellar Trade: Hemisu exports raw and refined etherium to other systems, ensuring its economic stability and interdependence with neighboring planets and star systems. Trade agreements and partnerships have enabled Hemisu to accumulate significant wealth, although they also expose the planet to external pressures and competition.

Shared economic contributions

The integration of Nemeans and humans has led to a mixed economy where both species play vital roles. While human settlers brought advanced mining techniques, logistics, and interstellar trade networks, the Nemeans’ deep knowledge of the land and sustainable resource management has been invaluable. Together, they have developed a balanced approach to exploiting etherium without exhausting the planet’s resources.

Challenges and economic inequities

Despite their interdependence, economic disparities persist between humans and Nemeans. Many Nemean communities still struggle to recover from the exploitation and displacement of earlier eras. Although the Council of Hemisu has implemented measures to ensure equitable economic opportunities, systemic issues remain, including unequal access to resources, education, and capital.

Diversification efforts

Recognizing the risks of over-reliance on etherium, Hemisu’s leaders have initiated efforts to diversify the economy. These initiatives include:

• Agricultural Innovation: Leveraging the planet’s diverse biomes to expand sustainable farming practices, reducing dependence on imports.
• Tourism: Promoting Hemisu’s unique landscapes and rich cultural heritage as a destination for off-world visitors.
• Renewable Resources: Investing in technologies that utilize other natural resources to complement etherium-based energy systems.
• Fishing: The Great Ocean has an abundance of marine life that contributes largely to local markets on Hemisu, and efforts are being made to expand that to the interstellar market.
