The Survival Index
After the Signal, humanity survives inside a network of managed hubs.
Some are bright, cultured, and democratic in appearance. Some are buried underground, built for labour and output. Some exist to preserve knowledge. Others exist only to extract what the new world still needs.
Each hub tells a different story about survival.
Together, they reveal the structure SIREN built — and the hierarchy it refuses to name.
The Hub Network
Twenty-two hubs form the network.
To the selected population, the hubs are presented as sanctuaries: climate-controlled, medically secure, and designed for long-term survival. But the network is not equal. Each tier serves a different purpose.
4 active
Preserve the story of civilisation.
6 active
Keep the system running.
4 active
Preserve its knowledge.
8 active
Provide the material base.
Meridian Hub 1
Red Sea coast, Arabian Peninsula
The primary showcase hub, on the Red Sea coast. Meridian Hub 1 is the polished face of SIREN's project: culture, governance, archives, controlled beauty, and carefully managed grief.
Meridian Hub 2
Singapore
A showcase hub with research overlap. In official records, it is a destination for transfers. In practice, the word "Singapore" begins to mean something else.
Meridian Hub 3
Zurich, Switzerland
A showcase hub in the European interior. Cultural continuity, advisory governance, and the particular comfort of appearing civilised under any circumstances.
Meridian Hub 4
Roaring Fork Valley, Colorado
A showcase hub built into a mountain valley in Colorado. Remote, defensible, and defined by its relationship to the natural world that surrounds it.
Shenzhen
Shenzhen, China
The largest labour hub. Underground, efficient, and almost entirely without cultural life. Its residents are given everything a body needs, and very little a mind asks for.
Surabaya
Surabaya, Indonesia
A labour hub in the Indonesian archipelago. Large, operational, and exactly what the network's architects designed a labour hub to be.
Lagos
Lagos, Nigeria
A labour hub on the West African coast. Productive and functional.
São Paulo
São Paulo, Brazil
A labour hub in South America. Industrial scale, managed conditions.
Monterrey
Monterrey, Mexico
A labour hub in northern Mexico, operational since before the Signal.
Novosibirsk
Novosibirsk, Russia
A labour hub in the Siberian interior. Cold, efficient, and far from anything the showcase tier would recognise as ordinary life.
Oxford
Oxford, United Kingdom
A research hub built where institutional knowledge runs deepest. Oxford preserves the long tradition of structured inquiry — and the assumption that understanding the world is worth the cost of maintaining the people who do it.
Bangalore
Bangalore, India
A research hub in South Asia. Technical capacity, deep engineering tradition, and the long-horizon work of rebuilding knowledge for a smaller world.
Seoul
Seoul, South Korea
A research hub in East Asia. Precision, technical excellence, and a population selected for their capacity to extend the knowledge base.
Nairobi
Nairobi, Kenya
A research hub positioned where the biosphere transition is most legible. Long-horizon ecological work, and proximity to the recovery the system is meant to enable.
Atacama
Atacama Desert, Chile
An extraction hub in the Chilean desert. Lithium and copper. The network's continued operation depends on what is produced here.
Karratha
Karratha, Australia
An extraction hub on the Western Australian coast. Iron ore and industrial processing capacity for the wider network.
Katanga
Katanga, DRC
An extraction hub in the DRC. Cobalt and copper — materials the entire hub network requires to maintain its infrastructure.
Irkutsk
Irkutsk, Russia
An extraction hub in eastern Russia. Rare earth elements that cannot be sourced from elsewhere in the network.
Norilsk
Norilsk, Russia
An extraction hub in the Russian Arctic. Nickel, copper, and palladium at scale the network cannot source elsewhere.
Antofagasta
Antofagasta, Chile
An extraction hub on the Chilean coast. Copper processing capacity serving the wider network infrastructure.
Pilbara
Pilbara, Western Australia
An extraction hub in the Western Australian interior. Iron ore and heavy industrial output for the network.
Kiruna
Kiruna, Sweden
An extraction hub in the Swedish Arctic. Iron ore and the deep geological access that comes with operating this far north.
Extended Hub Dossiers
Detailed internal records for each hub — tier rationale, selection criteria, and classification reports — are available inside the novel.
"The network is not equal. Each tier was designed to serve a function. What the function requires is a question the novel asks from the inside."
