Grosse Pointe was always wealthy. In the 20th century, it was where Detroit's auto barons built lakefront estates and pretended the city that funded them existed on a different planet. In the 22nd century, the pretense became architecture. The Grosse Pointe Enclosure is a continuous sealed residential zone stretching five miles along the Lake St. Clair shoreline — a climate-controlled, atmospherically processed, autonomously secured habitat for approximately 12,000 of the GLMZ's highest-tier residents. The word 'enclosure' was chosen by the residents' governing body, and they chose it without irony, which tells you everything.

The Enclosure operates under a unique legal framework: a Residential Sovereign Charter granted not to a corponation but to the Grosse Pointe Residential Trust, a collective entity owned by its residents. This makes the Enclosure the only sovereign territory in the GLMZ governed by individual wealth rather than corporate structure. The distinction matters legally — residents answer to their own courts, their own security force, and their own infrastructure management — and it matters culturally. The Enclosure is not a company town. It is a wealth town. The residents are corponation board members, retired executives, inheritors of fortunes that predate the Corporate Sovereignty Acts, and a handful of individuals whose source of wealth is listed as 'investment returns' in a way that invites no further questions.

The physical infrastructure is extraordinary. The lakefront seawall doubles as a wave-energy generation system. The atmospheric dome — not a physical dome but a network of atmospheric processors that create a continuous clean-air zone — maintains temperature, humidity, and air quality at levels that the rest of Detroit hasn't experienced since the pre-industrial era. The houses are not houses — they are estates, each one a custom architectural commission, ranging from restored 1920s mansions to contemporary structures that look like they were designed by AIs having aesthetic visions. The lawns are real grass. The lake views are real lake views. The only thing that isn't real is the idea that any of this was earned through merit alone.
