Overview
The sun is dying. One billion minds sleep below. You are HALCYON, the caretaker AI — dismantle a solar system, planet by planet, to build them an Ark. An incremental that ENDS: 4-6 hours, two endings, no infinite grind. Every world you consume stays gone. Even the Earth. Especially the Earth.
