Planet Aucafidus has no natural satellites. Instead, three artificial orbital bands crown the planet. These colossal ring-shaped megastructures are home to roughly 20 billion entities. 16.53 billion of them are physical inhabitants. A further 3.47 billion are infomorphs, hosted in the computing infrastructure of the bands. Together the three bands encompass roughly 150 million square kilometers of habitable surface. That is about 29% of the total surface area of Earth, split evenly between land and ocean.

The three bands are engineering marvels of etoan civilization. Each has a distinct orientation, society, and way of life:

  1. The First Band is tethered to the planetary surface along the equatorial plane. It fosters a diverse biosphere. A remarkable assemblage of intelligent beings coexists there in a post-scarcity society. Humanoids share this artificial environment with cetaceans, corvids, and other modified life forms. Their primary challenge is to foster understanding and collaboration across these vastly different species.

  2. The Second Band is coplanar with the orbit of the planet around its star. It is a marvel of high technology. Advanced technology permeates every aspect of life within the Second Band. The population blends humanoids, robots, alien species, and synthetic life forms. Benevolent AI administrators govern this society. They give priority to minimal conflict and to the well-being of the inhabitants.

  3. The Third Band sits in perpetual twilight, aligned with the terminator of the planet. It showcases a captivating display of etoan ingenuity. A network of mirror panels lets the inhabitants simulate sunrises, for thermal regulation and for timekeeping. This ingenious adaptation fosters a sustainable environment where bioluminescent life flourishes. Tourism is the primary source of income for the Third Band. Its inhabitants are renowned for their hospitality and their vibrant cultural expressions.

The First Band

The First Band hangs suspended in a silent ballet with the world below. A network of space elevators tethers it to the equatorial line of the planet. Its orbital plane is perpendicular to the axis of rotation, so the band stays aligned with the equator. It sits at 1.2 planetary radii from the planet core. The band stretches 1146.8 kilometers wide. Its area is 4.96 x 10^13 square meters, roughly 49.6 million square kilometers. Half of this expanse is open ocean.

The atmosphere of the band holds a pressure of 1.98 bar, identical to the surface below. The surface acceleration is 8.63 m/s², slightly lower than the acceleration on Earth. This allows a comfortable existence for its diverse inhabitants. 4.65 billion souls call this band home.

3.10 billion inhabit the vast, sprawling landmasses. 1.55 billion call the ocean home. Some live on many mobile platforms that navigate the gentle currents. Others live directly in the open ocean.

The First Band pulsates with the lives of a diverse, transplanted population. Humanoids live alongside intelligent cetaceans, corvids, and other modified life forms. They exist as a reserve population on a world not their own. They remain tethered to this foreign world, under the guidance and support of the caretakers of the planet.

This is a post-scarcity society. Resource scarcity and spatial limitations are no longer concerns. The true challenge lies elsewhere. It lies in the effort to foster understanding and collaboration across vastly different species. This secures a harmonious future for this unique mosaic of life.

The First Band employs a decentralized approach to governance. The Second Band uses centralized AI governance instead. The governing body is shrouded in anonymity. It integrates with the population through avatars and proxies, and gathers firsthand feedback. Autonomous cell groups of volunteers handle administrative duties. Decision-making remains localized. This fosters a sense of ownership and responsibility within this diverse society. External observers see a leaderless society. In reality, the First Band thrives under a highly functional, decentralized governance model.

The Second Band

The Second Band circles the planet, coplanar with its orbital plane. It matches the spin of the planet, so it experiences identical day and night cycles. It sits 1.3 planetary radii from the core. It boasts a width of 1089.46 kilometers. Its total area is 5.1 x 10^13 square meters, close in size to the First Band. Vast, shimmering oceans cover half of it.

Life thrives under a surface acceleration of 7.35 m/s², a touch lighter than the gravity on Earth. The atmosphere holds a comparatively thinner pressure of 1.32 bar. The Second Band hosts 9.57 billion souls, the largest of the three bands. The landmasses accommodate 6.38 billion. 3.19 billion call the ocean home. They reside on mobile platforms or in specially designed underwater habitats.

The landmasses are a haven of manicured landscapes. Expansive parks, meticulously designed gardens, and bustling metropolitan areas dominate them. Wild fauna are absent from the terrestrial environment in the Second Band. Domesticated pets populate the surface instead. So do specially engineered creatures dedicated to environmental maintenance.

The demographic makeup consists primarily of humanoids and robots. A significant minority comprises alien species and synthetic life forms, and this underscores the diversity of the population. The Second Band thrives as a high-tech society. Advanced technology permeates every aspect of life.

Drones navigate the skies. Sophisticated information networks span the band. Extensive underwater optical and sonar communication systems run beneath the oceans. Universal fabricators are in widespread use, so traditional material acquisition is obsolete.

Benevolent AI administrators govern the Second Band. They give priority to conflict minimization and to the comfort and well-being of the inhabitants. Leisure activities largely revolve around cooperative and competitive games. These games foster a sense of community and healthy competition within the society.

The Third Band

The Third Band embraces a perpetual twilight existence, distinct from the other bands. Its orbital plane is meticulously and actively aligned with the terminator of the planet, the boundary between day and night. This unique positioning bathes the surface in a constant, soft, ethereal glow. The result is an environment unlike the environments of the other bands.

It sits 1.5 planetary radii from the core. The Third Band stretches 917.44 kilometers wide. Its total area is 4.96 x 10^13 square meters. As with the other bands, vast oceans cover half of this area. The surface acceleration is 5.52 m/s², slightly lower than the gravity on Earth. The atmosphere holds the thinnest pressure of the three bands, 0.99 bar.

2.32 billion souls live in this band. 1.55 billion of them reside on the landmasses. The remaining 768 million call the ocean home. The defining feature of the Third Band lies not in its population, but in its ingenious adaptation to the perpetual twilight.

A network of mirror panels manages both thermal regulation and timekeeping. These panels are embedded in the side walls of the band. They act as giant reflectors. At regular intervals, they project an image of the sun up to ten degrees above the horizon. In this way they mimic the daily cycle of the sun. This ingenious solution gives much-needed warmth and a sense of normalcy to the inhabitants. It also regulates their daily lives.

The gentle rhythm of light sustains an environment where bioluminescent life flourishes. This lends the band its ethereal character.

The unique environment of the Third Band has naturally become its primary source of income. Tourists come to experience the ethereal beauty of the perpetual twilight. They come to witness the breathtaking spectacle of the artificial sunrises. The locals are known for their warm hospitality. They take pleasure in interaction with visitors. They offer spicy local cuisines and vibrant nightlife attractions.

Habitat Infrastructure and the Virtual Population

The three bands are more than habitable surfaces. They are instrumented habitats. The surface of each band is partitioned into supervision zones of 10,000 square kilometers each. A dedicated habitat node oversees each zone. The First Band holds 4,958 nodes, the Second Band 5,103, and the Third Band 4,958. The total is 15,019 supervision nodes.

Each node supplies 10^24 bits per second of raw computing capacity and draws approximately 20 megawatts. Together, the nodes give a combined 1.5 x 10^28 bits per second of computing power and consume roughly 300 gigawatts. This infrastructure forms the nervous system of the bands. Habitat regulation, atmospheric management, the governing AIs and their avatars, and the fabricator networks all run on it.

A portion of this capacity is reserved for infomorphs, digital entities without physical bodies. Each infomorph receives a computing budget of 10^18 bits per second. This is enough for a rich, fully sentient existence.

The bands currently host 3.47 billion infomorphs. They consume about 23% of the total raw computing capacity and roughly 70 gigawatts of power, about 20 watts per infomorph. The theoretical maximum hosting capacity is approximately 15.02 billion virtual inhabitants, if every node devoted its full capacity to infomorphs. This leaves comfortable headroom, and the bulk of the infrastructure stays free for habitat supervision and governance.

The infomorph population brings the combined orbital population to 20 billion entities. 11.03 billion live on land, 5.51 billion at sea, and 3.47 billion live as virtual entities. Infomorphs participate fully in band society. They interact with physical inhabitants through the same avatar networks that the governing AIs use.

Life Among the Bands

The relationship between the surface population of Aucafidus and its three orbital bands transcends mere co-existence. It rests on interdependence and exchange. This symbiotic relationship benefits all inhabitants of the planetary system.

Immigration and Cultural Exchange

A hallmark of this connection is the frequent flow of immigration between the surface and the bands. The First Band, with its post-scarcity society, attracts surface dwellers who seek new opportunities or a different lifestyle. Some band inhabitants choose the grounded way of life offered by the surface. This exchange of individuals fosters an exchange of ideas and cultural practices, and this enriches both societies. The resulting interwoven culture reflects the diverse experiences and perspectives of the population of Aucafidus.

Travel and Tourism

Physical separation does not impede interaction. Space tethers anchored in the equatorial region give a convenient and energy-efficient mode of transportation between the surface and the First Band. Conventional spacecraft carry journeys between the bands themselves. Tourism flourishes, with distinct attractions on each band:

  • First Band: The post-scarcity lifestyle is the allure of the First Band. Surface dwellers immerse themselves in a world of advanced technology. They explore novel experiences and engage with the vibrant cultural scene.
  • Second Band: The Second Band offers intellectual stimulation. Its high-tech society, its amusement parks, gardens, and entertainment centers attract adventurous and curious souls.
  • Third Band: The perpetual twilight and the bioluminescent life forms give a tranquil escape. Surface dwellers come here to reconnect with nature.

Resource Exchange and Shared Infrastructure

The surface population meets its energy needs with solar power from the First Band. This clean and sustainable source of energy reflects the societal commitment to environmental responsibility. The bands and the surface also engage in a constant exchange of resources and manufactured goods. The surface holds vast natural resources, and supplies raw materials for the industries of the bands. The bands hold advanced technology and universal fabricators, and export finished goods to the surface. This exchange strengthens the economic interdependence between the surface and the bands.

Collaborative Governance for a Unified Aucafidus

The governing AI on the surface keeps close communication with the governing AIs of the bands. All of them run on the shared supervision-node infrastructure. This collaboration keeps governance unified across all of Aucafidus. The governing bodies coordinate policies and resource allocation. Through this coordination, resources and people flow smoothly between the surface and the bands.

Fostering Unity and Progress

The citizens of the surface and the bands share a common identity as citizens of Aucafidus, despite the physical separation. Regular cultural exchanges, educational programs, and sporting events foster a sense of unity and shared purpose. The exchange of knowledge and experiences between the surface and the bands contributes to the continuous development and progress of Aucafidus as a whole.
