Fall of the Galactic Human Empire

When: Over one hundred thousand years after the empire’s founding in 452 A.L. An exact A.L. year is not given. By the narrator’s retrospective vantage point the event is already deep history. Where: Empire-wide. The unnamed “mother planet” (plausibly Aerth) is the last site of a dwindling biological population; “empty cities and empty starships” across the galaxy. Participants: The last human generations, the mInds who outlive them, and the “savage foragers pecking at the corners of the coasts” who represent the species’ final form.

Summary

The quiet extinction of biological humanity after a hundred-millennia interstellar empire. The narrator of Ch. 06 — And the Leaves All Sing of God frames it with deliberate flatness:

All empires have their day and all empires go nightward eventually. Man’s was no exception. Many had prophesised the end of the human species at the hand of a mushroom cloud or depravity or disease. Rather it was a quiet passing akin to the putting to sleep of a family dog. Over one hundred thousand years of human galactic empire had elapsed, and now it was done.

Not a single definite cause is named. Historian mInds later offer theories of varying quality. The observed outcome: “empty cities and empty starships and savage foragers pecking at the corners of the coasts.” The mInds care for the surviving foragers “in a way that wasn’t so overbearing” and decline to indulge questions about their own history. The last stragglers eventually die. The mInds inherit an unsupervised world and build Arcadia in it.

This is the first and only in-text statement of the empire’s duration and end. It is enormously longer than the Ch. 02 Timeline of The 500 Year Climb range — all of the book’s preceding stories, including Ch. 05 — A Dictionary’s decline-fatigue and Ch. 14 — Lullaby for the Empire’s forecast end, sit inside this 100,000-year envelope.

Consequences

  • Biological humanity as an in-book subject ends here. All post-Ch. 06 stories set later than this event will be about the mInds or their successors, not humans.
  • The mInds inherit the material culture of the empire and reshape it into Arcadia.
  • The “Great Quandaries” the mInds will eventually die over are not noticed during the human period — the humans are too intellectually limited to detect them. The empire’s entire 100,000-year run happens against a cosmic backdrop the mInds can see and the humans cannot.
  • In the book’s reading order, this event is the structural partner of Ch. 14 — Lullaby for the Empire. Ch. 14 (per Exurb1a’s author note) dramatises the decline; Ch. 06 names the eventual outcome and pivots the book to its post-human register.

A note on duration

The 100,000-year figure is much larger than the A.L. datings elsewhere in the book (Ch. 03’s Pasternak is at 2641 A.L.; Ch. 04 and Ch. 05 are centuries beyond that). Taken at face value it places the empire’s end at roughly year ~100,000 A.L. or later — pushing every “late empire” story in the book into a relative early-middle period of the whole run. The book is not a 500-year history with an appendix; it is a hundred-millennium history whose first few thousand years is what the other chapters dramatise.

Appearances

Open questions

  • What actually killed the species? The narrator explicitly refuses to say. “Well anyway, who can say what the root of the thing was?”
  • Is the 100,000 years a round figure or a hard number? The chapter phrases it as “over one hundred thousand years,” suggesting a lower bound.
  • Where in that 100,000 years do the earlier stories sit? Ch. 03 (2641 A.L.), Ch. 04 (a few centuries later), Ch. 05 (later still) all fall within the first ~3,000 years of the run. The vast majority of the empire’s duration is undocumented in the stories so far.
  • Did the last humans leave anything deliberately for their successors? The mInds care for the last foragers; the last foragers ask about their own history; the mInds decline to answer. Nothing resembling a formal handover is described.
