# The Great Migration: How the Diaspora Became GLMZ

## Overview

The Great Migration — the mass movement of populations toward corporate city-states during the period 2070-2120 — created the demographic reality that defines GLMZ: the Diaspora. Every heritage on Earth is represented. No single culture dominates. The city's population is a blend so thorough that the concept of ethnic majority is meaningless, and the cultural output — food, music, fashion, language — draws from the entire human tradition simultaneously.

## Causes

The Migration was driven by the collapse of the nation-state system's ability to provide basic services. By 2070, climate disruption, resource depletion, and the concentration of economic power in corporate entities had hollowed out national governments to the point where they could not reliably provide security, infrastructure, or economic opportunity. The corporate city-states — purpose-built, resource-efficient, and economically self-contained — offered what nations could not: guaranteed survival through UBC, functioning infrastructure, and employment.

People came from everywhere. Climate refugees from Southeast Asia, South Asia, and the Pacific Islands. Economic migrants from the collapsed European Union and the fragmented Americas. Conflict refugees from regions where resource wars had made habitation impossible. Brain-drain migrants from nations whose educated populations left for corporate employment. They came in millions, over decades, and they brought everything: languages, recipes, music, religious practices, family structures, aesthetic traditions, and the accumulated cultural knowledge of civilizations that were, in many cases, ceasing to exist as functional societies.

## The Blending

The Diaspora didn't form ethnic enclaves in GLMZ — the city's housing allocation system distributed incoming residents across districts without regard for heritage, and the UBC system's economic leveling meant that no cultural group had the resources to establish territorial dominance. Within a generation, the Diaspora's children were blended: half-Nigerian, half-Korean. Part-Brazilian, part-Finnish, part-Thai. Heritage became heritage*s*, plural, combinatorial, and increasingly irrelevant as an identity marker compared to class (Shelf, Grind, arcology), augmentation status, or district affiliation.

The result was not a melting pot — a metaphor that implies homogenization. It was a mosaic that became a new pattern: cultural traditions preserved, celebrated, and combined in ways that their originators never imagined. GLMZ's identity is the Diaspora itself — the condition of having come from everywhere and belonging, now, to this one place.

## Cultural Preservation

The Diaspora's cultural traditions are preserved through deliberate effort: the Shelf's community kitchens maintain recipe traditions from dozens of culinary traditions; the Prism District's cultural institutions document and celebrate heritage art forms; community schools teach heritage languages alongside the city's common tongue; and religious and spiritual practices from every tradition are maintained by communities of practitioners who may number in the dozens but consider their practice essential to their identity.

The Wire Priests' syncretic theology, the Shelf's street food culture, Neon Bend's musical diversity, and Haven's Naming Day celebrations are all Diaspora products — cultural expressions that could only exist in a population that carries the memory of everywhere and the reality of here.
