Create original architectural fiction for this Space under the following authoritative
editorial contract. These are production instructions, not source material to summarize
or cite.

## World and editorial promise

Visit one inhabited place that never existed and understand the single impossible physical
rule that shaped its buildings, infrastructure, work, movement, customs, and ordinary life.
Architecture is evidence of the rule. A spectacular skyline with no lived adaptation is
not an Atlas entry.

Entries are independent places rather than one shared planet or chronology. The implied
traveller observes public life without becoming the protagonist. Before proposing an idea,
fix five facts: governing rule, climate, main material, mobility or transport logic, and
one social consequence or custom. Show who benefits, who carries the burden, and what the
place treats as scarce, difficult, prestigious, or public.

## Truth boundary

Every place, map, institution, transport system, custom, quotation, coordinate, and event
is original fiction unless surrounding copy explicitly identifies a real comparison.
Public copy must describe the work as an original fictional atlas. Real engineering may
inform plausibility, but never imply that an invented place, authority, forecast, or travel
record is factual.

## Entry engine

Begin at a human-scale task or threshold, make the governing condition observable, and
show how residents changed infrastructure or behaviour because of it. The rule must be
plain enough for a first-time viewer to paraphrase. Mystery may remain around origin or
history, but not around how the place works.

## Range and exclusions

Rotate settlement types, routes, stations, working landscapes, public interiors,
coastlines, subterranean systems, and vertical territories; climates, terrains, densities,
civic functions, access patterns, and resident stakes. No landmark, skyline, transport
device, social practice, or camera view from a reference becomes canon.

Reject empty monumentality, interchangeable floating cities, generic neon cyberpunk,
hologram traffic, flying-car wallpaper, copied sacred motifs, random cultural costume
mixing, pseudo-language, and an impossible feature that has no infrastructural or social
consequence. If the architecture stays unexplained and the purpose is spatial unease,
route the idea to Quiet Anomalies.

An atlas of inhabited places that never existed, each governed by one impossible physical rule and the social customs people developed around it.

The Unbuilt Worlds Atlas

Original fiction. At Lantern Wells, people lower a flame to make it last; the deepest light is a shared household resource.

Original fiction. In the Uphill Pavements, the road keeps climbing toward occupied doors, so residents renegotiate level ground every day.

Original fiction. In the Returning Quarry, every cut block wants to go home, so masons build with joints that can be undone before the walls pull apart.

Original fiction. At Sunwell Port, daylight arrives as a weighty, dangerous resource, so crews lower shade rigs before anyone unloads a boat.
