Celestials
Celestials are the long-lived, heavily engineered post-human clades that dominate the Centauri Cluster in Exodus: The Archimedes Engine. They are so far removed from Earthly origins that it is hard to remember they and late arkship humans were once the same species. They are not one empire or one body plan: Crown Imperial Celestials, Heresy hexapods, Talloch-Te traders, and older Remnant powers all fall under the Celestial label — united more by power and evolutionary distance from baseline humans than by a single culture.
From settlers to gods
When the first arkships reached Centauri they found dense star systems and thousands of empty but habitable Eden worlds — products of ancient planetary engineering. Over roughly twenty millennia, early colonists spread, built empires that rose and fell, and changed until later arrivals named them Celestials. Today’s great dominions (including the Crown) are mere shadows of the sprawling empires that came before: Centauri is a graveyard of civilizations whose marvels survive as dangerous Remnants.
The book’s deep past layers include the Elohim of the Dawn Era, who used Archimedes Engines to move worlds into stellar life bands and terraform them; the Remnant Era of later engineering traces (such as Dolod’s flight path); and Formation Wars that left strangelets, ghost armies, and legends of powers like the Pouli and Détenir. Celestials of the novel’s “present” inherit that stack: they rule Eden worlds they did not create, use Ghost constructs mass-produced in ages of total war, and still dig into Elohim megastructures when politics demands it.
Many forms, many dominions
Celestial evolution takes many paths out of the Dawn Times. In the novel’s opening archon meeting:
- Imperial Crown Celestials (Wynid, Verak, and sister houses) are tall humanoids with long limbs — queens can reach ~3 m. Children grow height early and finish broadening later: a seven-year-old is already over 2 m but still narrow, and only widens after ten, when puberty triggers the final growth of the marsupial womb both sexes carry. Hair and skin colour vary freely within a line — a queen’s daughters may share nothing of her looks but her eye colour. They prize mindline immortality and mock shorter-lived Celestials as “children.” Court fashion includes bloodstone growths — a calcium-like biotech in faint turquoise and gold — that spread from the skull in scalloped horns and a body-wide lacework until they entomb a host body and the mindline moves on.
- Heresy Celestials (archon Olomo) are ~3 m spindly hexapods — two legs, four arms, four eyes, skulls drawn out into cones level with the shoulders over an inflated brain, and a low body temperature that keeps it cool. Their skin is almost reptilian, tight enough to read as an exoskeleton in blues and greens, and the two arm pairs differ: the upper ends in elongated three-jointed fingers, the lower in a triple claw. Short individual lives (centuries) by Crown standards, but powerful ships and research reach.
- Talloch-Te are nomad traders and shipbuilders with a multi-body architecture (primary and secondary bodies, mind partition, bodymorph, including a “gravity form”). Archon Sahdiah’s primary biological body has five eyes. Verak’s royal house aligns with them in the helium-politics subplot.
Further Celestial types and cultures include the Deva, the Keledai, and the Mara Yama as an external threat. The politics the novel stages are Crown-centred, with Heresy and Talloch-Te as peer Great Game players and Mara Yama as the crisis pretext for fleet massing.
Queens, archons, mindlines, and riders
Crown queenship is embodied by figures such as Helena-Chione of Wynid and Carolien-Amaia of Verak. Continuity of identity and knowledge passes through the mindline — neural-cultural transfer that can elevate congregants into princesses or queens, and that Thyra hijacks to become Helena-Thyra. An Imperial Celestial brain may retain only a few centuries of detailed memory; choosing what to gift the next host is itself statecraft.
Archons are the operators of Celestial policy: Chief Archon Lord Gahiji serves Helena until hardliners edge him out; Makaio-Yalbo / Makaio-Faraji links Wynid spycraft to Terence Wilson-Fletcher’s investigations; peers such as Sahdiah and Olomo run parallel briefs for other dominions. Archons use riders — temporary personality overlays tuned for diplomacy or ruthlessness — and induction-pad greetings that exchange perceptual signatures. Archons run bureaucracies, deniable assets, loyalty tests, and occasionally neural overrides that treat human lives as expendable instruments.
Hierarchy below the clade
Celestials sit at the top of Cluster civilization. Below them:
- Uranics — intermediate humans with neural interfaces who can work livestone and other Celestial materials, often as client aristocrats and labour managers.
- Baseline / late arkship humans (e.g. Diligent settlers) — economically useful, politically constrained, culturally alien to post-human courts.
- Travelers — free-ranging ship humans who trade, salvage Remnants, and sometimes serve as deniable Celestial cutouts.
Celestial Dominions control vast swaths of Centauri and despise late arrivals as primitive. In the novel that contempt coexists with pragmatic use — human farms on Gondiar, ore on Anoosha, mercenaries and ghost units when deniability matters.
Great Game politics in the novel
Celestial politics is long-horizon competition measured in decades and millennia. Helium scoop fleets make decade-long flights, some forty years separate Olomo’s warning about Dolod’s approach to Kelowan from Carolien’s coronation, fleets position themselves years ahead of a supposed Mara Yama confrontation, and annexation talk reaches toward Capo Frois and the Uthara Dominion. Hardline and institutional factions disagree on tempo more than on hierarchy — Thyra’s coup reframes Wynid as “dynamic leadership” against external threats while still crushing human unrest at home.
Outside formal courts, Celestials use Travelers, mercenaries, and funding trails as deniable tools. ZPZ races, ghost-fleet assaults, and liberation funding often resolve to archon-level agendas (for example Sahdiah’s interest in removing “random factors” like the Diligent). The novel’s climax — Engine commands, Boksrock geometry, palace sabotage — is Great Game endgame as much as rebellion victory or defeat.
