Lanzhou
Lanzhou is an early human colony that became a major commercial hub after slipstream travel. Its low-gravity vertical cities are known for deep archives, institutional wealth, and a culture of privacy and discretion. Lanzhou City includes government records offices, elevated tramways, private spaceports, and wealthy historic districts shaped by old family estates.

Lanzhou was settled by human colonists before slipstream travel was perfected, when voyages could take nearly half a year. After Reinhardt-Vance announced the first slipstream-capable drive, Lanzhou rapidly grew from a small settlement into a commercial hub with a multi-million population and large daily inflows of new settlers. It is five jumps from Corvalis City. Lanzhou is an early-to-mid wave world with deep archives and deeper privacy, the kind of place where records can disappear legally and still remain properly filed. Low gravity encourages dense vertical cities and a culture that values discretion over spectacle. Money here tends to be old, quiet, and institutional, expressed in endowments, sealed collections, and private holdings rather than monuments. Lanzhou City rises in layered construction where early colony blocks sit beneath newer skins of concrete, glass, and weathered ceramic cladding. Mist drifts between towers, elevated trams run on magnetic rails, and government offices and archives remain central to the city’s institutional character. The city includes a private spaceport on its edge outside the old administrative quarter, as well as wealthy historic districts marked by old estates built for permanence rather than display. Lanzhou’s unusually long day is divided into locally standardized work and rest blocks rather than conventional mornings and evenings. Urban lighting and climate systems create artificial cycles inside the major cities. Old estates outside Lanzhou City are prized for privacy, independent power, and archival storage, making them suitable refuges for people wealthy enough to disappear without seeming to flee.
