Sector 7 is a Liminal installation built beneath a city. It was not built and then compromised. The site was selected: the sampling point was there first, and the facility was poured around it.
Since the Sector 7 incident Sector 7 has persisted as an addressable lattice, with the breach RIFT-01 open inside it. Liminal's operatives enter it by projection through Project T-Link. Contractors on Recovery contracts enter it in person.
Layout
The lowest level is the original works: a single containment ring poured directly around the sampling point, small, unlit, and older than every drawing that references it. Each later expansion was added above the last, wider and further from the ring, until the uppermost levels held administration, records, and personnel who had never been below Grade 3.
The building is therefore read downward as a history and upward as a defence. Depth correlates with age, with proximity to RIFT-01, and with the instability of the lattice. The Containment Sciences Division has repeatedly declined to publish the original survey.
Levels on record
| Level | What the records hold |
|---|---|
| Floor 1 | The ring, the original works, around the sampling point |
| Floor 2 | The plant: six halls above the ring |
| Floors 3 to 5 | The upper grades, ending at the top hatch |
| Unlisted | Subgrade levels reached by freight lift from Coldharbor interchange, floors withheld |
From the surface
The city above does not name the facility. Its traces reach the surface as freight orders for LIMINAL SUBGRADE, a lift in Meridian Tower that stops at floors nobody lists, warm air from a maintenance shaft at 02:00, and a sealed subgrade lift in the survey level beneath the lit floor.
