Highland Park was already a city within a city — an incorporated enclave like Hamtramck, but without Hamtramck's community cohesion or economic base. When Chrysler left in the 1990s, it took the tax base with it. When the water was shut off in the 2010s, it took the pretense of municipal services. When the Corporate Sovereignty Acts passed in the 2040s, no corponation bothered to claim Highland Park because there was nothing to claim. Three square miles of crumbling infrastructure, contaminated soil, and 8,000 people who couldn't afford to leave. The corponations didn't conquer Highland Park. They simply decided it wasn't worth conquering.

What grew in that vacuum is the HPAZ — the Highland Park Autonomous Zone, an unincorporated, ungoverned, and officially non-existent territory that has become the GLMZ's most radical experiment in post-corporate living. The HPAZ has no government, no police force, no tax structure, and no formal economy. What it has is a network of mutual aid collectives, squatter communities, urban homesteaders, anarchist tech cooperatives, and approximately 11,000 people who are building something that doesn't have a name yet because naming it would require agreeing on what it is. The old Chrysler headquarters — a brutalist concrete campus that has been slowly colonized by residents, workshops, and a hydroponic farm that fills the former executive parking garage — serves as the closest thing the HPAZ has to a center.

The zone is dangerous. There is no emergency response infrastructure. Medical care is provided by volunteer medics with varying degrees of training. Disputes are resolved through community mediation or, when mediation fails, through means that range from social ostracism to violence. The power grid is a patchwork of stolen connections, solar installations, and a biomass generator that runs on organic waste and smells exactly like you'd expect. But the HPAZ is also genuinely free in a way that nowhere else in the GLMZ is. No corporate surveillance. No tier classification. No neural interface monitoring. No jurisdiction of any kind. For the people who live here, that freedom is worth everything it costs. For the people who visit, the costs are usually more apparent than the freedom.
