Sanctuary Shattered Sun Story & Campaign Overview
Year 2758 lore on the Dyson Sphere Sanctuary, the three factions at war, and what the Steam demo previews of the full campaign.
Story & Campaign Overview
The year is 2758. Humanity’s greatest achievement — Sanctuary, a star-encompassing Dyson Sphere housing over a trillion lives — has become a battlefield. Gleaming cities lie in rubble; climate systems and structural rings are weapons as much as infrastructure.
The Three Allegiances
- EDA — pragmatic Earth Defence Alliance, mass industry and overwhelming firepower
- Guard — Sanctuary’s builders turned sentinels, drones and expendable waves
- Chosen — post-human elite with shields and devastating energy weapons
Your King-Piece commander is both narrative anchor and hard lose condition.
What the Demo Shows
The July 21, 2026 Steam demo ships single-player scenarios (tutorials, story beats, survival/skirmish-style maps depending on build notes) — not the finished epic campaign. Treat it as a lore and systems appetizer. Full campaign length is a headline Early Access / 1.0 deliverable on our release date tracker.
Themes You Will Feel In-Game
Map-breaking superweapons, weather control that freezes oceans, and late Titans all reinforce the fiction: war on Sanctuary can permanently scar the megastructure.
