// SENTINEL-7 // OPEN FREQUENCY // ORIGIN: CITADEL ZERO

The planet is dead. The cities are dust, the sky the colour of old rust. Out in the ruins the watchers are moving — patient, mutated, closing on the one structure that still holds power.

The last citadel. Its lights are still on. Its archive still answers.

It has been waiting a long time for someone to take command. That's you. The Architect.

  • CHRONICLE — The citadel lies at the end of a long road, across the worlds the disaster left behind. You cross them one by one — ash-choked ruins, fields of bone, a forge still burning among the stars — and at the edge of each, something vast and patient stands in your way. Bring it down, and the next world opens. Cross them all, and the gates finally rise before you.
  • CONTRACTS — You reached the citadel. Now you never leave it. The dark pours out its numbers, again and again, and there is no final one to defeat — only the walls, and you, and how long you can keep them standing.
  • ASCENSION — You were not the only one who lived. Somewhere in the wastes, another Architect raised their own citadel — and now they've come for yours. Will against will, until one still stands and the other is dust.

You do not hold those walls with your bare hands. You call your defenders up out of the citadel's old archive — no two the same, some far mightier than others, a rare few waking with powers all their own. What answers your call is never quite what answered anyone else's.

The gate is open, Architect. The citadel remembers what the planet forgot. Stand ready — and hold the line.

— Sentinel-7
