Location from The Expanse by James S.A. Corey
Colony world where High Consul Winston Duarte built an authoritarian empire using Ring Builder orbital shipyards. Named for ancient Sparta's discipline. Protomolecule technology gave Laconia weapons that made conventional fleets obsolete.
Laconia is Mars perfected and perverted. Duarte took the best of Martian military culture — discipline, long-term planning, willingness to sacrifice for a goal — and applied it to building an empire rather than terraforming a planet. He chose Laconia because it had what no other colony world offered: Ring Builder orbital construction platforms that could build warships using protomolecule-derived technology. For thirty years, Laconia was silent behind its ring gate, building. Duarte used the time to construct a military that could challenge the entire rest of humanity, a government modeled on benevolent authoritarianism, and a society that believed it was saving the species from the existential threat of the Ring Builder killers. The children who grew up on Laconia — like Teresa Duarte — knew no other life. They were raised to believe in the empire, in the High Consul, in the necessity of unified human governance under Laconian authority. The planet produced true believers with advanced weapons, which is the most dangerous combination in any political system. Laconia also harbored the dogs — alien repair drones that could resurrect the dead, discovered by children like Cara and Xan. The planet's Ring Builder technology didn't just build ships. It touched everything, in ways Duarte's scientists catalogued but never fully controlled.
A habitable world with Earth-like gravity, blue skies, and terrestrial vegetation transplanted alongside native alien growth. The capital city is built with Martian efficiency scaled up to imperial ambition — clean lines, planned streets, and government buildings designed to project authority. Above the planet, Ring Builder orbital construction platforms drift in stable orbits — massive alien structures that Laconia's engineers learned to operate, producing warships using technology humanity didn't invent. The platforms pulse with faint protomolecule luminescence, alive in ways human factories are not.
