The Proxima Incident

A city-sized starship. An alien hive mind. 312 people with no way out.

About this adventure

The year is 2562. After decades of geopolitical fragmentation and climate catastrophe, humanity found unexpected unity in a single technological miracle: faster-than-light travel. The Helios Compact — a coalition of the five most powerful technology corporations in human history — has poured forty years and untold trillions into the Arca Mundi, a vessel unlike anything ever built. Part starship, part city, part monument to human ambition, it carries 312 souls bound for Proxima Centauri and the promise of a second home among the stars. But the FTL drive is loud. Louder than anyone anticipated. The exotic particle emissions from a single test jump three years prior created a beacon that propagated across forty light-years in every direction — a dinner bell rung in the dark. When the Arca Mundi finally departed Earth orbit in April 2562, something was already listening. Something that had been waiting patiently in the cold between the stars for exactly this kind of signal. The Vreth are not what humanity imagined when it dreamed of alien life. They are not individuals. They are a distributed hive consciousness that propagates through biological infiltration — converting and absorbing nervous systems into their collective. They move silently, work through hosts, and their single directive is expansion. They reached the Arca Mundi six weeks into the journey, carried aboard by a resupply drone no one thought twice about. By the time anyone noticed something was wrong, the ship's lower decks had already changed. Now the Arca Mundi is a sealed world hurtling through the dark. The mission commanders refuse to abort — they are too close, they say, and the investors are watching. Some crew members follow orders out of loyalty, fear, or ambition. Others are no longer entirely themselves. And somewhere in the middle of it all, a handful of people must find a way to take back the ship, survive the betrayals, and bring humanity home — even if home turns out to be somewhere no one planned to land.

Prologue

The stars outside the viewport don't move. At this velocity, in the silence between solar systems, the universe looks exactly the same as it always has — indifferent, ancient, and vast beyond comprehension. You have been traveling for six weeks. Earth is already too far to feel. Something changed three days ago. Small things at first — a technician who stopped making eye contact, a section of Deck Nine sealed without explanation, a low harmonic vibration felt in the walls rather than heard. The kind of wrongness that lives in the gut before it reaches the brain. The ship carries 312 people and enough supplies for five years. It was built to be self-sufficient, to survive anything the void between stars could throw at it. Nobody planned for a threat that was already inside.
