Megacorporations — The Major Players and Their Domains

power

The legal term is Interplanetary Corporation. The legal term describes an entity chartered under UTCA regulations, with licensed operations spanning two or more star systems, authorized to hold territorial claims, operate private security forces, and enter binding contracts with colonial governments.

Nobody uses the legal term.

Megacorporations are what people call them — on the street, in the media, in whispered conversations in bars where the walls might be listening. Megacorp. It carries the weight of what these organizations actually are: sovereign entities in all but name, vertically integrated economies that build their own ships, grow their own food, train their own armies, and answer to no authority that they do not also fund.

Vertical Integration

Every major IPC is, functionally, a civilization.

A mining corporation does not merely mine. It manufactures the equipment used in mining. It builds the ships that haul ore. It operates the refineries that process raw materials into sellable commodities. It runs banks that finance its own operations and lend against its own output. It grows food in hydroponic facilities anchored to mining platforms, where solar radiation and proximity to water ice make agriculture cheaper than importing from agricultural worlds. It trains and deploys its own security forces to protect its claims. It runs medical facilities, schools for workers’ children, media channels for company towns, and legal departments that dwarf most colonial judiciaries.

The same pattern applies to every major IPC, regardless of origin industry. A shipbuilding company also mines the ore for its hulls. A technology company also manufactures its own components. A defense contractor also builds the ships it sells. The core competency is the center of gravity: the thing a corp was founded to do, the thing it does better than anyone else. Everything else radiates outward from it, a complete economy designed to minimize dependency on anyone outside the corporate boundary.

This self-sufficiency is the point. An IPC that depends on another IPC for a critical input is an IPC that can be leveraged, strangled, or absorbed. The logic of vertical integration is the logic of siege warfare: control your own supply lines, or someone else will cut them.

Greed and Paranoia

Greed and paranoia are institutional imperatives, bred into corporate culture over two centuries of interstellar competition.

Greed because the incentive structure demands growth. Market share, territorial claims, resource access, labor pool, technological advantage — the metrics that determine a corp’s relative position are all zero-sum. What one corp gains, another loses. Quarterly earnings reports are obituaries for someone else’s margin.

Paranoia because every competitor is doing the same thing. Corporate espionage isn’t a scandal — it’s a line item. Every major IPC operates intelligence divisions that would be called spy agencies if governments ran them. Moles are planted. Executives are turned. Research is stolen. Workforce poaching is standard, and the poached employee may be a genuine recruit or a carefully placed asset whose real employer is still paying their salary. Honey traps — deliberately exposing an attractive target (a researcher, a prototype, a contract) to bait a competitor into revealing their intelligence capabilities — are routine.

The result is that every relationship between IPCs is transactional. Alliances exist only as long as both parties profit, and both parties are simultaneously looking for the moment when betrayal pays better than cooperation. Joint ventures are temporary. Partnerships are conditional. Loyalty ends when the credits clear.

This extends downward. Employees are assets. Assets that underperform are liquidated — not killed, usually, but discarded with an efficiency that makes the distinction academic for the person being discarded. Workers understand this. The ones who survive long enough to be useful develop a mercenary pragmatism that mirrors the institution they serve. Trust is local, personal, and never extended to the company itself.

The Five

Five IPCs dominate Terran Occupied Space. Between them, they control the majority of interstellar commerce, territorial holdings, and critical infrastructure. They are not the only corporations — hundreds of smaller IPCs, regional operators, and specialty firms operate in their shadows — but they are the ones that set the terms everyone else operates under.

Tessaract Mining Corporation

Origin: Resource extraction. Founded during the first wave of interstellar expansion, when the corps that could deliver raw materials from new systems to the hungry industries of Sol and Alpha Centauri wrote their own terms.

Core competency: Deep-crust mining, asteroid extraction, gas giant operations. Tessaract drills deeper, claims wider, and extracts more tonnage than any other entity in TOS. Their claims span every distance tier from the Core to the Frontier, and their prospecting teams routinely operate beyond the Frontier boundary on speculative charters.

Tessaract’s mining is the foundation of the interstellar economy. The rare-earth minerals, heavy metals, and exotic materials that feed every other industry — shipbuilding, cybernetics, weapons manufacturing, construction — come disproportionately from Tessaract claims. This gives them leverage that transcends market share. When Tessaract adjusts extraction quotas, commodity prices across TOS shift within the communication lag window.

Vertical reach: Ore processing and refinery complexes. Specialized shipbuilding division producing mining vessels, haulers, and support craft. Commodity-backed lending and futures trading. Hydroponics and food production facilities anchored to mining platforms throughout the belt regions. Private security forces capable of enforcing claim boundaries by force. Medical and worker support infrastructure across dozens of systems.

Culture: Rough, practical, and risk-tolerant to a degree that other corps find alarming. Mining is inherently dangerous — deep-crust operations on geologically active worlds, zero-gravity extraction in debris fields, gas skimming in radiation-heavy environments. Tessaract breeds a workforce that accepts risk as baseline and treats casualties as operational cost. There is a genuine solidarity among miners, a shared-hardship bond that Tessaract cultivates because loyal miners are productive miners. The company disposes of damaged assets without sentiment, but it keeps the functional ones fed, housed, and proud of the TMC patch on their suit.

The Unseen World: Tessaract digs deeper than anyone, which means Tessaract finds things that no one else finds.

The Silence of Kandris-III was a Tessaract operation — 11,000 people vanished when their automated boring systems cracked an ancient Seal at 3,800 meters. That was the worst incident. It wasn’t the first, and it wasn’t the last.

Tessaract’s internal incident database contains dozens of entries classified under “geological anomaly” — unexplained temperature drops in deep shafts, equipment that activates without power in sealed tunnels, workers who emerge from shifts changed in ways that medical evaluation cannot explain. Site managers who have been in the field long enough learn to read the signs: when the rock gets cold and the instruments start lying, you pull the crew and seal the bore. Some of them do this. Some of them keep drilling because the quarterly targets don’t adjust for ghosts.

Tessaract’s leadership knows something is down there. Their institutional response has been classification, relocation, and continued drilling. The data on subsurface anomalies is the most comprehensive in TOS, and Tessaract doesn’t share it. What they have assembled amounts to a partial map of sealed sites, Shroud boundaries, and Ancient Dark intrusions across dozens of worlds — information that would be invaluable to anyone trying to understand the pattern. It sits in a classified database, used primarily to route drilling operations around the most dangerous sites. Primarily.

Meridian Dynamics

Origin: Defense contracting. Military hardware, weapons systems, and the research infrastructure to develop them. Meridian grew out of Earth-era defense industries and followed the money into interstellar space, where corporate security needs and UTCA military contracts provided a reliable revenue stream.

Core competency: Weapons manufacturing, military vehicle and ship systems, corporate security services, advanced materials research. Meridian builds the things that kill people and the things that protect people from being killed, and it does both for any client with the budget.

Vertical reach: General manufacturing and materials processing. Shipbuilding focused on military and security vessels. Logistics and transport. Financial services. Training academies for corporate security personnel. Limited food production and worker support infrastructure — Meridian outsources more than the other Five and compensates with tighter operational control over what it does own.

Culture: Compartmentalized, disciplined, and paranoid even by IPC standards. Meridian’s military heritage shows in its organizational structure — information flows up, orders flow down, and lateral communication between divisions requires authorization. Employees operate on need-to-know. The average Meridian worker knows their job, their team, and nothing about what happens two floors up. This is presented as security culture. It is also a control mechanism that ensures no single employee understands enough of the picture to be a meaningful threat if turned.

The Unseen World: The Baltimore Event was Meridian’s. Their classified lab in Baltimore’s industrial district was studying anomalous objects recovered from deep mining sites — Shroud-marked artifacts that their researchers did not understand. The experiment that breached the Shroud killed 847 people and required an Obsidian Court intervention to contain.

Meridian’s response to Baltimore was to get better at containment.

Their Special Projects Division, an open secret in corporate intelligence circles, is the most sophisticated corporate operation studying the Unseen World. Where other corps stumble onto anomalies and classify them, Meridian actively seeks them out. They have recruited researchers with backgrounds in occult studies, comparative religion, and theoretical physics. They have acquired artifacts through channels that range from legal salvage to outright theft from rival research programs. They have established containment facilities designed to hold anomalous objects and — it is rumored — entities that are not objects.

Meridian is the IPC most actively attempting to weaponize what it has found. Their progress is unknown outside the Division. Their containment protocols, built on lessons learned at Baltimore, are more thorough than any other corporate operation — and still almost certainly inadequate for what they are attempting to contain.

Nakamura-Stellar

Origin: Exploration and survey. Nakamura-Stellar was chartered to map the frontier — to find the systems, chart the routes, and file the initial assessments that determine which stars are worth the investment of colonization. They are the ones who go first.

Core competency: Deep-space cartography, system survey, navigational infrastructure, communication relay networks. Nakamura-Stellar operates the largest fleet of survey vessels in TOS and maintains significant portions of the tight-beam relay network that carries interstellar communications. They don’t own the settled systems — they find them, map them, and sell the data to the corps that develop them.

Vertical reach: Navigation systems and stellar cartographic databases. Communication relay construction and maintenance. Specialized shipbuilding for survey vessels and deep-space platforms. Limited mining (survey-adjacent prospecting). Frontier supply depots and staging posts. A smaller overall footprint than the other Five, compensated by the irreplaceable value of what they know.

Culture: Intellectual, insular, and increasingly haunted. Nakamura-Stellar crews spend months or years in deep space, operating at the edge of mapped territory. This breeds a particular temperament — independent, self-reliant, comfortable with isolation. Since the Irkalla, it also breeds a specific kind of anxiety. Survey crews know that the frontier contains things that the briefing packets do not cover. The ones who have been out far enough know that some of those things are aware of them.

Nakamura-Stellar hoards information the way Tessaract hoards mineral rights. Their survey databases are the most comprehensive record of what lies beyond the colony worlds, and access is sold selectively, at prices that reflect the monopoly. Customers receive the data they pay for. What they don’t receive are the annotations — the marginal notes, the route deviations with no stated justification, the survey results marked with codes that translate to “do not develop” or “do not approach.”

The Unseen World: The survey vessel Irkalla was Nakamura-Stellar’s ship. Forty-seven crew sent into the Kessler Void under UTCA contract. None returned. The final transmission described something that perceived the crew as a frequency and was tuning in.

Nakamura-Stellar knows more about what occupies deep space than any other human organization. Their cartographic data includes the boundaries of the Kessler Void, mapped from safe distance after the Irkalla’s loss. It includes other regions — other places where surveys returned data that was wrong in ways the instruments could not explain. Their field teams have encountered anomalies on frontier worlds that align with the pattern described in Unseen intelligence channels: Gossamer thinning, Shroud disturbance, the specific quality of wrongness that accompanies Ancient Dark proximity.

This data is Nakamura-Stellar’s most valuable asset and its most closely guarded secret. Selling navigational information that says “this system is safe to develop” is profitable. Selling data that says “something in this system will dissolve your mining crew’s cognitive function” would be more honest but less commercially viable. The tension between these imperatives defines Nakamura-Stellar’s institutional character: cartographers who have mapped the edge of something that should not be mapped, unsure whether sharing the map would save civilization or destroy their quarterly revenue.

Sternberg Group

Origin: Orbital construction and shipbuilding. Sternberg built the first generation of colony habitats, the early stations, and the freighters that connected them. When humanity needed infrastructure in space, Sternberg provided it.

Core competency: Ship construction, orbital habitat fabrication, dome infrastructure, station building. Sternberg operates the largest section of the Meridian Yards in Alpha Centauri and holds dome construction contracts across TOS. If it floats in vacuum or keeps air pressure on the right side of a wall, there is a better than even chance that Sternberg built it.

Vertical reach: Materials processing and alloy manufacturing. Heavy mining feeding construction supply chains. Worker housing and training academies across the Core and Inner Colonies. Atmospheric processing equipment. Structural engineering services. The largest per-capita workforce of any IPC — building things at interstellar scale requires bodies, and Sternberg employs more of them than anyone.

Culture: The most blue-collar of the Five. Sternberg’s workforce is enormous — hundreds of thousands of welders, fabricators, engineers, systems technicians, and construction crews spread across every major system. There is an institutional pride in building things that other people live inside. Sternberg workers know that the dome holding atmosphere for a million colonists was assembled by people like them, and that knowledge creates a specific kind of identity.

Sternberg has the strongest labor tradition of any major IPC — unions existed here once, and though they have been systematically gutted, the culture of collective identity persists in informal ways that management tolerates because the alternative is worse. A Sternberg yard crew that decides to down tools can shut down ship production for weeks. This has happened. The negotiations that followed were not polite.

The Unseen World: Sternberg’s exposure to the Unseen has been incidental rather than deliberate. They build infrastructure, and sometimes that infrastructure gets built on sites that turn out to be wrong. Construction crews have stories — cold spots in new station sections that don’t correspond to thermal models, structural materials that corrode in patterns metallurgy cannot explain, sealed sections of older stations where the atmosphere readings are normal but nobody volunteers to enter.

Sternberg’s institutional response has been to ignore these reports, attribute them to worker superstition, and occasionally redesign a structure to route traffic away from a section that nobody can account for.

What Sternberg doesn’t realize is that its construction data — decades of structural surveys, geological assessments, and foundation analyses conducted before building on colony worlds — contains a partial map of anomalous sites. They have surveyed the ground before building on it, and their surveys have inadvertently catalogued locations where the veils are thin, the Shroud is disturbed, or something in the substrate does not match the expected geology. This data has never been analyzed for patterns. If it were, the picture would be alarming.

Helix Technologies

Origin: Electronics and cybernetic augmentation. Helix emerged from the consolidation of Earth-era technology companies and rode the cybernetics boom into interstellar dominance. They make the implants that two-thirds of the human population carry.

Core competency: Neural implants, cybernetic augmentation systems, Net infrastructure, AI development, consumer electronics. Helix is the most consumer-facing of the Five — the one whose brand is in people’s heads, literally. Their cortical mesh is the baseline augmentation for any worker who can afford it or whose employer requires it. Their overlay interfaces layer data onto the physical world for billions of users. Their Net infrastructure carries a significant portion of interstellar data traffic.

Vertical reach: Implant manufacturing and component fabrication. Medical device production. Communications hardware. Data processing centers. Financial technology platforms. Consumer goods manufacturing. A growing pharmaceutical division — implant maintenance requires anti-rejection medication, and Helix discovered early that selling the drug that keeps the implant functional is more profitable than selling the implant itself.

Culture: Corporate sleek. Helix sells the future — clean, connected, augmented, efficient. The marketing is aspirational. The reality is manufacturing floors where workers assemble implants under conditions that would violate regulations if the regulations had not been written by Helix lobbyists. The contrast between Helix’s brand image and its operational reality is the most visible example of corporate hypocrisy in TOS, which is a competitive field.

Helix is the most image-conscious of the Five. Public relations matters here in a way it doesn’t at Tessaract or Meridian. Scandals are managed. Narratives are controlled. When a batch of cortical meshes causes rejection syndrome in a frontier colony, the communications response is deployed before the medical response. Brand damage costs more than wrongful death settlements.

The Unseen World: Helix has stumbled onto something significant, and they are only beginning to understand what it means.

Cybernetic implants, specifically neural implants with metallic components integrated into the brain and nervous system, interfere with supernatural perception and psychic compulsion. Fae glamours falter against augmented senses. Vampire psychic influence struggles to reach through a cortical mesh. The Gossamer, which resonates with air and vacuum, is opposed by metal — and Helix has been putting metal into human skulls for decades.

This was not intentional. It is an accident of engineering. But the implications are enormous.

Helix’s research division has identified the anomaly — implanted subjects show statistically significant resistance to certain categories of perceptual manipulation in controlled testing. They don’t know they’re testing resistance to fae glamour. They think they’re studying a neurological side effect. The data is filed under “anomalous perceptual resilience” and “implant-mediated cognitive stability.” The researchers are confused by their own results. The results are reproducible.

The vampires, who have relied on psychic compulsion for millennia, consider the spread of cybernetic augmentation an existential threat. Certain factions within the Unseen World — particularly the Bridger vampires seeking mortal allies — view Helix’s technology as humanity’s best accidental defense. Others view it as a problem to be neutralized before Helix’s researchers connect what they are measuring to what is actually happening.

Helix doesn’t yet have an Unseen team. They don’t yet know the Unseen World exists. When they find out — when their researchers finally correlate their perceptual resilience data with the reports filtering through intelligence channels — the consequences will reshape the balance of power between every faction. The corporation that accidentally armed humanity against supernatural compulsion will become the most strategically significant entity in TOS.

Whether Helix survives that discovery is an open question.

Everyone Else

The Five are not the entire corporate landscape. Hundreds of smaller IPCs, regional operators, and specialty firms inhabit the spaces between the majors.

Regional IPCs hold territorial claims and operational charters in specific systems or clusters. They lack interstellar reach but dominate their local economies. Some are genuinely independent. Some are subsidiaries or fronts for one of the Five, providing deniability for work that the parent company doesn’t want on its books.

Specialty operators fill niches that the majors’ vertical integration does not cover efficiently — courier services, salvage operations, luxury goods, entertainment media, legal services, and a hundred other specializations. They exist at the pleasure of the Five: tolerated when useful, absorbed or crushed when inconvenient.

Wildcatters operate at the frontier, where corporate oversight is thin and the gap between “independent prospector” and “pirate” is a matter of paperwork. Some are genuine entrepreneurs. Some are backed by a major IPC’s intelligence division as deniable assets. Telling the difference requires better intelligence than most people have access to.

The competitive dynamics between the Five create space for all of these smaller players. An enemy of your enemy is a potential client, and mid-tier corps frequently find themselves hired by one major to undermine another. This is the economy that freelance operators, fixers, and runners inhabit — the contested space between corporate boundaries where deniable work needs doing and the Five need hands that are not wearing their patch.

The Black Budget

Every major IPC maintains classified programs that do not appear in public filings. The budgets are buried in line items labeled “special projects,” “security research,” or “risk assessment.” The personnel are recruited through channels that bypass standard human resources. The work is compartmentalized so thoroughly that most corporate employees — including most executives — have no idea it exists.

The Unseen World operations are the most closely guarded of these programs. Corporate Unseen teams — typically five to twelve operatives — investigate anomalies, negotiate with supernatural factions, recover artifacts, and contain threats that would compromise corporate assets if left unchecked. These teams report to a handful of executives who understand that the Unseen World isn’t a mystery to be solved but a market to be entered.

The teams are composed primarily of humans with relevant skills: combat specialists, investigators, negotiators, technical experts. Some include vampires who have found corporate employment more reliable than Dominion patronage. A few include individuals with training or aptitude that allows them to perceive or interact with the veils directly — remnants of the guardian traditions that modernity discarded, now drawing a corporate salary.

At least three of the Five — Tessaract, Meridian Dynamics, and Nakamura-Stellar — maintain active Unseen teams. Meridian’s are the most sophisticated. Tessaract’s are the most field-experienced. Nakamura-Stellar’s know the most about what lies beyond the frontier and share the least.

What none of them possess, what no human institution possesses, is a coherent strategy for dealing with the Ancient Dark. The corporate approach to the Unseen World is the corporate approach to everything: exploit, contain, profit. This works reasonably well for Shroud breaches and fae negotiations. It doesn’t work for a cosmic-scale threat that corrodes the structure of reality by proximity. The Five are bringing quarterly earnings logic to a problem that operates on geological time, and the gap between what they are prepared for and what is actually happening grows wider with every survey mission that does not come back.
