The Burn War — Year 41

The Burn advances. The Ecumene denies. The last of humanity remembers.

Year 25,490 of the Capital — the 41st year of the Burn War. The Flood has been consuming the galaxy for nearly 245 years, and the Forerunner Ecumene, gods who built worlds for ten million years, still calls it a quarantine. The Perimeter holds, barely. The Builders fund their terrible rings in secret. And in the dark between the wars, the last free humans hide from the Burn and the hunters alike — carrying a warning nine thousand years old. Step in as the Ember Remnant at the edge of the Burn, or hold Shield World 0459 against the first spores. A living world that remembers everything it takes.

Author's note

Set 50 years before the canonical firing of the Halo Array.

Minor fan additions included (like small pockets of human survivors, hunted by Forerunners).
