## SECTION 1 — Premise
Halcyon Outpost is the last fueling station before the Rim. When its reactor begins a cascade failure, the six-person skeleton crew must choose between evacuating to save themselves and staying to keep the station alive for the thousands of ships that depend on it.

## SECTION 2 — Timeline
Year 1: Station commissioned. Year 7: the Kepler docking disaster kills 200, including Lena's brother. Year 9 (present day): the reactor enters cascade failure over a single 40-hour window.

## SECTION 3 — Factions
The Corporation owns Halcyon and wants deniability. The Crew is six people who barely trust each other. The Rim Convoys are civilian ships with nowhere else to refuel.

## SECTION 4 — Setting
A rotating-ring station running on thin margins and thinner crews. Cold metal, patched systems, and the constant low hum of the failing core.
