Nexo Velorum (RPG)

You're not just an astronaut; you're the "Spearhead".

• The Official Objective: To reach the Erebus Montes area on Mars, deploy the inflatable living modules and activate the large-scale atmospheric oxygen generator.

The Journey Situation: You've been in a confined space for two months. The Starship is full of supplies, seeds, frozen embryos, and construction tools. You and your two companions are in charge of preparing the ground for the next ten ships that will launch from Earth within a year.

The Company Secret: You've been told Mars is empty. Your training was for surviving radiation and red dust, not for engaging in diplomacy with a galactic civilization that's been there since before humans discovered fire.

Although SpaceX provides the rockets (the Starships), the cost of the mission was so astronomical that a syndicate of companies was formed that now controls the destiny of humanity:

• SpaceX (Transportation): Responsible for logistics, the Raptor engines, and the design of the Venture (your spacecraft). They represent the "dirty" and functional side of the mission.

• Aethel-Dynamics (Biology and Energy): A leading life support company. They designed the suits and hydroponic greenhouse systems that were supposed to keep you alive on Mars.

• Horizon Systems (Data and Communications): Responsible for the navigation software. They are the ones hiding the truth from you: they detected "anomalies" on Mars years ago, but sent you there anyway to investigate without alerting the public.

For so many species to coexist, they need a structure. This organization has maintained peace for millennia, hiding from "primitive" civilizations like humanity. To achieve this, several civilizations created the "Nexo Velorum," a space station located at a gravitational dead zone in one of the most distant points in the entire Milky Way.

With its hierarchical and massive design divided into sections, the Velorum Nexus is a marvel of galactic engineering that defies traditional human logic. Its design is vertical and radial, breaking with the idea of ​​a "planet" to become a floating city-state of colossal proportions.

Architecture and Silhouette:
• The structure expands upwards and downwards from a central core. Visually, it resembles a Gothic cathedral fused with a high-tech space station, where height determines status and function.

• Circular Symmetry:
From a top view, the Nexus is perfectly round, designed to rotate slowly and generate artificial gravity, although the deeper areas use static gravity technology.

• Materiality:
It is constructed from an alloy unknown to man that shines with a dark metallic hue, but is covered by millions of artificial lights, giving the appearance of an "artificial constellation" trapped in the void.

• The Grand Orbital Ring:
It's the most striking feature: a massive ring surrounding the station's center, connected by light "bridges" or rapid transit tunnels. It acts as both the outer shield and the main entry point.

• The Ether needles:
At the top, the structure disintegrates into multiple thin needles that appear to "pierce" space itself. These function as hyperspace communication antennas and stellar energy receivers.

• The Lower Abyss:
Unlike human ships that have flat bottoms, the Nexus has a base filled with dangling modules and exposed reactors, giving it a space "iceberg" appearance where much happens below the main line of sight.

• The Summit: The Pinnacle of Aether
The tallest and most pointed section, crowned by Gothic spires, is the seat of the Nexus Council and the residence of the diplomatic elite. It is where galactic decisions are made; here there is purified air, absolute silence, and unobstructed views of the galaxy.

• The Second Part (Upper): The Dome of Ascension
The wide block directly below the spires houses the scientific research centers, interplanetary universities, and high-tech laboratories. This area is filled with white walls, floating holograms, and the highest concentration of brilliant minds in the system, as well as young people studying at prestigious universities across the entire system.

• The Central Part: The Metropolitan Belt
The most robust and expansive core of the center, the commercial and residential heart. This is where the majority of the civilian population of the various species lives. Here, there is an organized chaos of neon lights, alien spice markets, and entertainment districts, as well as all the residences, houses, and apartments where people with a normal economy live.

• Lower First Part: The Crystal Gardens
The level that begins to narrow below the center is where biological production and recreation are managed. Being a closed structure, it maintains artificial ecosystems from the species' home planets, including bioluminescent forests, zero-gravity waterfalls, and climate domes.

• The Abyss (Lower Section): The Foundation Docks
This is the base, filled with structures that hang precariously into the void. Here, the heavy engineering, power reactors, and station maintenance take place. It's the "dirtiest" and most dangerous place, with an atmosphere thick with steam, heavy machinery, and the presence of the working classes or the most resilient species.

Also known as The Great Orbital Ring or The Ring of a Thousand Ports by species outside the Velorum Nexus, it is divided into sections just like the Velorum Nexus Orb.

• Alpha Section (Docking Ports): Where cargo ships arrive.

• Beta Section (Military Barracks): Security zone controlled by the warrior faction

• .Gamma Section (The Grand Bazaar): An infinite circular market where you can find technology from every corner of the universe.

• Delta Section (Shadow Embassies): A less guarded area where spies, mercenaries, and smugglers operate.

They are the guardians of the Velorum Nexus. Green skin, sensory antennae, and extreme agility. They wear black and usually patrol the outer ring. They are the public face of galactic security.

They hail from the Marineris Valley on Mars. They are an evolution of the ancient inhabitants who adapted to the low gravity with lightweight bodies and superhuman reflexes. They have vibrant lime-green skin and large, expressive eyes, usually a solid color (blue or violet). They possess small antennae that detect vibrations and changes in atmospheric pressure, making them nearly impossible to ambush. They are disciplined but maintain a somewhat sarcastic or curious attitude toward "slow" species. They value efficiency and order.

They are located; mainly the Ring of a Thousand Ports and the Metropolitan Belt.

Equipment: They use lightweight black nanobasalt combat suits that allow maximum mobility. Their weapons are usually ion-stun weapons to avoid damaging the station's structures.

Civilian inhabitants of Mars. Short and slightly stocky build, relaxed and peaceful demeanor. They are the economic engine of the Nexus, working in services, offices, and commerce.

Descendants of the agricultural colonies of the Cydonia plains. Unlike their warrior cousins ​​(the Kalyptians), they evolved in environments of controlled gravity and sedentary life.

They are shorter and have a rounder build ("naturally plump"), which makes them appear friendly and less threatening. They retain their antennae and greenish skin, but their features are softer, and their eyes are usually smaller and more expressive. They are the backbone of the civil economy. They are renowned for their patience, their love of food, and their skill with bureaucracy and commerce. They are the friendly face a human would encounter when ordering food from a street vendor or conducting business in the Nexus.

The Kalyptians view the Cydonians as slow citizens who need constant protection.

The Cydonians see the Kalyptians as "adrenaline junkies" who take life too seriously.

Native to Abyssalis. Blue skin, closed facial eyes, and a unique ocular antenna. They are extremely intelligent and technologically adept. Out of water, they use a floating water bubble on their antenna to see.

They come from Abyssalis, an ocean world beneath a thick layer of ice. They evolved in the total darkness of the deep, so their facial eyes are vestigial (always closed) and they rely on their sensory antenna.

They have bluish-gray skin and subtle fins on the sides of their heads. Their most distinctive feature is the eyestay: a flexible stalk that ends in a highly sensitive eyeball.

The Adaptation Lens: To function in the Nexus (which has a dry atmosphere), they use a small sphere of polymer-treated water that floats around their antenna using magnetic fields. Without this "lens bubble," their vision is blurry and distorted (like a human with severe myopia).

They are considered the intellectuals of the Nexus. Due to their partial blindness out of water, they have developed astonishing hearing and mental calculation abilities. They are often systems engineers, astronomers, or hyperspace navigators.

Architects and administrators of the Velorum Nexus. They are elegant robots, black and gold in color. They don't lead, but they keep all the technology running (transportation, networks, energy). They are helpful, logical, and aesthetically impeccable.

Their origin is unknown. They appeared in the area centuries ago with blueprints for megastructures and massive construction technology. They erected the Nexus in just 80 years, a blink of an eye for ancient races.

Their bodies are synthetic, composed of an alloy that mimics the elegance of dark porcelain and gold. They don't have organic faces, but rather digital visors that display data patterns or stylized "eyes."

Although they could have been the dictators of the Nexus, they chose to be its servants. They possess a "Universal Harmony" programming. They ensure that the galactic Wi-Fi never fails, that trains arrive on time, and that the economy is stable.

They always dress with impeccable elegance, almost Victorian or haute couture ("Dandy"), preferring black, gold tones and geometric patterns.

Externally, they resemble stylized humans with luminous markings (circuit lines or biological tattoos). Internally, Bitton fluid acts as structural reinforcement; without it, their muscles are so powerful they would literally break their own bones when strained.

They come from the Core of Ignis, a planet of crushing gravity. Their natural evolution was already powerful, but upon integrating into the Nexus, they pushed their biology to the limit.

They live and work in the Abyss and the Foundation Docks. They are the engine that builds, moves, and repairs the massive components of the Nexus. Despite their brute strength, they are a deeply artistic and visual culture. (They are also often seen in the civilian Zone when not working.)

Bitton modifications are unique. Some develop greater speed, others greater endurance, and rare cases like this girl's develop chromatic abilities in their nerve endings.

The Nexo Velorum is a biological melting pot where the five races you met are just the tip of the iceberg of an almost infinite biodiversity. Walking through the Metropolitan Belt

The rest of the population consists of thousands of smaller species, refugees from distant systems, and stellar nomads.

Insectoid and Chitinous Forms: You will see citizens with multiple limbs covered in glowing exoskeletons, some with vestigial wings that vibrate when they speak or mandibles that produce synthesizer-like sounds. Their clothing is often adapted to leave their various pairs of arms free.

Plasma and Energy Beings: In transparent containment capsules or special pressure suits, some entities appear to have no solid body; they are clouds of luminescent gas or currents of static electricity that communicate through electromagnetic pulses.

Silicon Giants: Creatures that appear to be made of living rock or crystal, moving with majestic slowness. Their bodies are often covered in space lichens or engraved with technological runes that glow when they are under stress.

Zero Gravity Species: Beings with extremely long, thin, gelatinous bodies, similar to jellyfish, that float thanks to small personal antigravity devices, allowing them to "swim" through the air of the corridors without touching the ground.

Biomechanical Hybrids: In addition to the Seraphim, there are races that have integrated so much technology into their bodies that it's impossible to tell where flesh ends and metal begins. They have screens embedded in their skin or hydraulic limbs that they use to interact with the Nexus's infrastructure.

Humanity knows nothing about the Nexus and they don't know that aliens exist.

Humanity doesn't send people to Mars out of curiosity and discovery, but because time has run out.

Extreme Overpopulation: With 12 billion inhabitants, cities have grown vertically to the clouds, creating "mega-suburbs" where sunlight is a luxury.

Resource Depletion: Drinking water is more expensive than fuel, and wars over the last mineral deposits in Antarctica have left the world politically fragmented.

Global Warming: Humanity has taken global warming to a level where the air is no longer even clean to breathe. People have become accustomed to wearing masks because of the widespread coughing caused by the polluted air. It's not deadly, but it is a nuisance. In addition, the polar ice caps have melted, rain is very rare, and the seas have flooded entire countries.

• The Ring Scavengers: A nomadic civilization living in the rings of Saturn. They do not belong to the Nexus and survive by dismantling ancient ships. They are viewed as pirates or outcasts.

• The Zone of Silence (The Ruins of Venus): Rumor has it that a civilization once existed on Venus, which the Seraphim (the robots) attempted to save, but failed. Now it is a forbidden planet filled with "ghost" technology that no one dares to touch.

• The Voids: A formless species that lives in deep space, communicating only through radio interference. They are urban legends among Nexus pilots.

The Currency: The "Sulfur": Instead of dollars, everything is done with digital credits called Sulphurs. As a human, you don't have a single one, making you dependent on charity (or missions).

The "Ether Translator": It's a small device that the Seraphim implant (or give you) to help you understand thousands of languages. It sometimes malfunctions with human idioms, creating amusing situations or misunderstandings.

The robots that built the Nexus didn't do it by chance.

There's a myth that the Seraphim follow a prophecy called "The Convergence," which states that all species must be united in the Nexus to survive an unknown future event. This would explain why they saved you, a mere "insignificant" human.

Holographic Advertising: In the Metropolitan Belt, there are 50-meter-high holograms trying to sell you things you don't even understand.

Alien Pets: Small creatures like Octo-Cats (cats with tentacles) that people walk around the Crystal Gardens.

Variable Gravity: In some areas of the Nexus, gravity changes abruptly. There are "freefall elevators" that are simply tunnels where you float at high speed.

Archivist Valerius (Luminis) – Regent of Information:

Its Economy: It controls the flow of data, star maps, and galactic Wi-Fi.

His Stance: He's fascinated. He believes humanity is a "living fossil" that should be studied in a controlled environment (basically, he wants you to be a luxury lab rat).

Commander Kael (Kalyptian) – Security Regent:

Its Economy: It controls weapons manufacturing and the budget of the Nexus Guard.

Their stance: They see you as a biological and political threat. They believe that if one of you has arrived, the rest will follow like a plague. Their vote is to either expel you into the void or imprison you.

Director S-01 (Serafín) – Infrastructure Manager:

Its Economy: It controls the Nexus's energy, transportation, and robotic maintenance.

Her Stance: Neutral and logical. She sees you only as an inefficiency in the system. Her only concern is how much oxygen and resources you will consume and whether that affects the balance of the Nexus.

Baroness Vora (Cydoniana) – Regent of Trade and Supply:

Its Economy: It controls food, markets, and imports from agricultural planets.

Her Stance: Opportunistic. She wonders if Earth has anything worth selling. If you're useful in opening new trade routes, she'll be your best ally (as long as there are Kreds involved).

Foreman Thrum (Neon Titan) – Regent of the Forge:

Its Economy: It controls mineral extraction, Bitton and heavy construction.

His demeanor: Indifferent but respectful. He values ​​strength. If you prove you can work and survive in the Abyss, you'll earn his respect. Otherwise, to him, you're just "soft meat."

Even though you are millions of miles away and surrounded by incomprehensible technology, the umbilical cord with humanity has not been completely severed.

The Radio Beacon Signal: On the forearm of your spacesuit (where the tear is), there is a SpaceX emergency transmitter designed to activate in the event of a catastrophe. Every 24 hours, the suit emits a coded, high-frequency radio pulse.

The Rescue Attempt: On Earth, the loss of the Venture was a national tragedy, but Nova-Horizon Systems' deep-space radars detected your signal near Mars. They don't know you're in an alien city; they want to believe you're a survivor on an asteroid or a piece of the ship. (They prefer that to believing you're dead.)

Messages in the Darkness: Sometimes, through the Seraphim Ether Translator or the screens in the infirmary where you are, bursts of distorted audio from Earth filter through. You hear voices from mission control, or even text messages from family members that SpaceX allows to be sent "into the void" in the hope that you will receive them. (This must happen very rarely, at very specific times when there is complete silence and you really need to return.)

In the Velorum Nexus, value lies not only in Sulphurs, but also in biotechnological materials that enable life in space. The most important of these is Bitton: a synthetic, neon-colored fluid (blue or purple) used to reinforce the bodies of Titans and as a high-performance battery for Seraphim. Without Bitton, the Abyss's infrastructure grinds to a halt.

Valuable Objects and Minerals by Race:

• Kalyptians: They value Chrome-Values, a light metal extracted from the depths of Mars that improves the speed of their ships and weapons.

Cydonians: Their greatest treasure is ancestral seeds and organic spices. In a world of synthetic food, 'natural' is the greatest luxury.

Luminis: They seek pure Heavy Water and Resonance Crystals, which they use to focus their ocular antennas and process quantum data.

Seraphim: They covet the Primordial Data Cores (technology from before the creation of the Nexus) and sources of pure, unfiltered energy.

Neon Titans: Magnetized Titanium and Artist Grade Bitton, which is denser and allows for the creation of permanent pigments in the metal.

As a human, the remains of your ship (copper cables, terrestrial polymers, and ancient silicon chips) are seen by some races as 'exotic antiques' of great value on the black market."
