Ordered markers for the history behind and within
Exodus: The Archimedes Engine. Macro context (Sol exodus,
Centauri Cluster settlement,
Celestial dominions) is brief; most rows cover the novel’s
multi-decade span from Dolod detection through the
Archimedes Engine climax. All calendar
years are approximate: they are reconstructed from “N years ago” dialogue spoken under
heavy time dilation, so the figures below are working labels rather than a canon calendar.

~40,000 years before main action
Humanity flees a dying Earth on arkships; early fleets settle the dense Centauri Cluster.
First-wave descendants evolve into Celestials and found dominions under systems such as the
Imperial Accord.
Later arkship waves arrive as Uranic and baseline humans under Celestial client rule.
Megastructures (including Archimedes Engines) reshape orbits and economies across the Cluster.
Dolod detected on a trajectory toward the Kelowan system; archon networks (e.g. Olomo to
Wynid contacts) begin long-term tracking decades before the main plot beats.
Imperial coronation era: Carolien-Amaia receives the rotating Empress throne for a sixty-year
term. Helena-Chione’s liaison with Bekket around this court cycle leads to Thyra’s birth.
On Gondiar, Terence builds an informant network after the Younes case; Dagon/Gyvoy trails are
suppressed by Governor-level orders. Celestial analysis and immolations mark the case as
more than street crime.
Arkship Diligent arrives near Kinnox. Josias and Ellie crash on Anoosha and rescue
Finn after Liliana dumps him. Hafnir land deal agreed; party returns to Gondiar; arkship
reclaimed under navy escort that disables rival entropy drives.
Alliances and salvage: Gath refit the Diligent; Gyvoy offers ZPZ path for entropy
drives; Finn/Ellie/Toše ride the Enfoe hull
Lestari to the Terrik Papuan salvage, under attack from Andino/Marcellu’s
Arcadia’s Moon and ghost fleets. Talloch-Te archon Sahdiah wants the ZPZ denied.
Thyra’s congregant trials (combat, survival, politics). Rivals die; thought-shielding and
Bekket heritage revelations; elevation to princess and deep mindline gift from Helena.
Terence’s Wynid loyalty test overlaps the first trial.
Hafnir community grows; Josias marries Otylia; Regal Democrats and Advisory Council footholds.
Finn and Ellie return with a ZPZ (years out, months subjective). Engine OS plan: Kingsnest.
Liberation funding trails (Tinaja) draw Terence’s attention.
Liliana kills Marcellu; Medusa tasked by Sahdiah. Uulana-Lyon’s investigation into Bekket
ends in slowball assassination; his ship is wrecked and discarded at Tonobo.
Kajval dropship extraction in Hoa Quinzu (ghosts, saberstones, Elsbeth McQuillan). Kingsnest
Engine factory: OS acquired under pirate/ghost pressure; Diligent turns for home.
Imperial crackdown: navy lockdown of Gondiar; Jalgori-Tobu displacement; Josias’s strike
broadcast; Marchioness and Variaka killed in airstrikes. Toše’s orbital-capsule bomb kills
Lucia, and Terence matches Liliana’s face to the old Gyvoy meeting. Flights on Arcadia’s Moon
(disguised) and Polkadav. Thyra’s fleet arrives early at Kelowan. Kestrel-sprite
sabotage over the imperial palace. Archons warned about Gyvoy imposture; vectors toward Dolod.
Diligent returns after ~32 years out-system. Engine climax on Dolod: momentum
transfers toward Boksrock; anchor ships; second transfer accelerates Diligent via
ZPZ/anchor coupling. Ellie recovers Gyvoy coercion memories. Carolien’s position collapses;
kill orders on the fleeing arkship; resistance and hardline courts both still in play.
Relativistic travel means shipboard months can equal years of Cluster history — Finn’s ZPZ and
Kingsnest arcs leave Gondiar politics transformed on return.
Court, detective, and arkship threads are concurrent; the table is a reading-order scaffold,
not a claim of perfect simultaneity.
