Ninefold Celestial War Command — The Stolen Sky of Constantinople

A bronze mechanism has been found beneath an old observatory in occupied Constantinople. Its markings shift when a second key is held nearby. The hobgoblin captain of the district orders every witness confined, but the instrument has begun signalling to something far beyond the city. The prisoner who first recognised its purpose insists that opening the gate could bring back an enemy long thought extinct.

What Is Happening Right Now?

The Dominion took Constantinople in 1453. Its officers now catalogue confiscated navigational manuscripts, broken vessels and ancient gates under military guard. Some commanders would trade those objects for guns, food and useful alliances; others want a weapon to threaten their earthly neighbours. The difficulty is not obtaining craftsmen but finding anyone who understands the entire system. One device may be a passage, another a warning and a third a lock made to remain closed.

Places and People

The Confiscated Observatory

Former imperial observers are questioned beneath the instruments they once maintained. A star chart has been rewritten to omit a destination whose name still survives on the mechanism itself.

The Iron Depot

Captured hull fragments, pressure vessels and alien materials are kept behind two rings of guards. An engineer has discovered that two identical parts become dangerously active when brought together.

The Prisoner’s Chamber

A scholar who once copied celestial records will speak only to a neutral envoy. The captain fears a lie; the prisoner fears that the truth will be acted upon immediately.

Rivals and Bargains

The Dominion is a hobgoblin state, distinct from the orc successor khanates and the human Ottoman realms. Ming ships could give it range that captured instruments cannot. Kemet preserves older gatekeeping practices that it cannot compel by threat. Richelieu buys secrets from escaped clerks, while Prague’s astronomers are attempting to identify fragments without knowing their origin.

The War Command’s Practical Ambition

The Ninefold Dominion has soldiers, workshops, siege engineers, military surveyors and tightly organised supply trains. In Constantinople it has also acquired devices it did not build. Its strength is fitting a recovered mechanism into a controlled expedition: guards, interpreters, rationed stores, secured doors and orders carried through a strict chain of command. Its weakness is that a seized engine or portal may fail when the coerced specialist is gone. The Dominion cannot transform every fragment in the city into a reliable warship.

Routes the Generals Covet

The Moon: a defensible observation or landing post would allow the war command to learn about departures from Earth. Officers want a place from which they could watch, negotiate or intercept travellers, but they have not established an unrestricted imperial base. Intercepted rumours tell the war command of Three-Marks Refuge, a small Ming outpost. The Dominion has no garrison or recognised access there and must first establish whether its stolen charts are accurate.

Ancient stations: confiscated charts point towards abandoned structures and sealed arsenals. Some devices may be weapons, while others are containment systems never intended to be opened. A commander’s mistake could endanger his own troops.

Mars: the lure is not a barren piece of land but an intact machine, independent ally or source of valuable material. An invasion would require far more provisions, transports and knowledge than a single stolen passage provides.

Why Rival Powers Resist

Capturing an inhabited station does not grant the Dominion every route passing through it. Local keepers may disable the mechanism, conceal the keys or demand an exchange of prisoners. Some hobgoblin officers recognise the usefulness of a negotiated treaty; others prefer force, setting their own commands against each other. The steppe orcs are neither Dominion subjects nor natural allies merely because both have threatened the Ming.

Three Journeys

The Missing Key

Recover an instrument carried west by refugees before a Dominion patrol overtakes them. Its owner wants it destroyed, not sold.

The Silent Gate

Help a captive surveyor prove that a portal does not lead where its military map claims. The wrong route could release an imprisoned threat.

The Three Seals

Three rival hobgoblin officers have each ordered a captured device moved to a different depot. A courier needs an escort and a way to decide which order is genuine.

Travel Beyond Earth

Captured technology is not a working fleet. Any launch requires sealed hulls, air, food, trained crews and astronomical observations. Ancient gates are easier to seize than to operate, and the Dominion cannot command inhabitants of other worlds merely because it occupies a city on Earth.
