Holy City Flying Fortress

Holy City Flying Fortress names the state in which the Holy City becomes a mobile airborne stronghold. The transformation is first experienced not as triumph but as violent disorientation: the laboratory rises with red alarms blaring, the floor shakes beneath Jack, and the city itself begins to move. Once the immediate danger passes, the airborne city becomes the central material question of the campaign. It is a damaged sanctuary, a military asset, a repository of secrets, and a possible home for people whose country has been overrun.

Activation and Immediate Crisis

The fortress state begins with a sudden mechanical upheaval inside the laboratory. Jack initially suspects a trap, but the rising floor reveals that the laboratory is moving upward rather than collapsing or being attacked from below. He uses Float to stabilize himself and calls Jessica through the COM-LINK, only to hear her report that the entire city is moving and that it is a flying fortress. The communication then fails, leaving Jack without an account of the wider situation and turning the city’s ascent into an unstable emergency rather than a controlled maneuver.

The transformation also changes the meaning of the Holy City’s sacred architecture. Earlier, Lita explains that the Theocracy’s Saint Citri statue, the likeness of Sahaqiel, protects the city by limiting the power of demonspawn attackers. The city therefore rises while carrying a religious center whose value is simultaneously spiritual, defensive, and political. The airborne fortress is not merely a machine that happens to contain civilians; it is a sanctified stronghold whose physical survival and symbolic authority are inseparable.

A Gift and a Disputed Prize

The city’s appearance in the sky is later presented as a deliberate offering from the Black King. Python shows Jack a massive flying city and describes it as a “baby shower gift,” a grotesquely intimate phrase that connects a military threat to Ada and Jack’s unborn child. The object’s scale rivals the Imperial Solarus, making clear that the gift is not a token or isolated weapon but a strategic structure capable of altering the balance between the factions.

The gift is also associated with the Green Bishop and with augmentations covered in the same mutagen that prevents healing. That connection makes the fortress suspect even before its secrets are understood. The city may be useful, but it arrives through enemy violence, biological contamination, and a chain of motives that Jack recognizes as too convenient. Its mobility therefore produces strategic opportunity and ethical danger at the same time.

Jack’s Proposal for Preservation

Selfia wants the floating city brought into Imperial territory for analysis, while Lita and the remnants of the Theocracy want to keep it. Jack refuses to treat the issue as a simple contest over military property. After spending fifty-six hours fighting alongside the city’s defenders, he argues that taking the fortress away would mean abandoning the people who survived with it.

His solution is to move the city together with its inhabitants. The land below is lost, ruined, and crawling with hordes of demonspawn; remaining there would likely result in the survivors’ eventual destruction. Jack proposes bringing the airborne city into imperial territory, settling its people in neutral territory, and recognizing it as a free city. The arrangement would preserve their lives while giving the Empire access to the fortress and to whatever secrets lie beneath it. In this formulation, evacuation becomes statecraft: a military retreat is recast as the foundation of a new political community.

Technology, Bodies, and Hidden Knowledge

The fortress belongs to a world in which the boundaries between magic, data, machines, and living bodies have already broken down. Sahaqiel explains that the Infinity Machine reads the flow of what people call mana as data, translates the molecules of matter, and connects beings across the world through a system comparable to a giant server and router. The airborne Holy City consequently appears not as an isolated miracle but as another node in a technological-spiritual infrastructure capable of moving matter, regulating power, and reshaping societies.

That infrastructure has a human cost. In a later confrontation, Tangerine tears open a Khloros cockpit and discovers a green-haired girl, not even a teenager, wired into machines and fleshy tendrils, her body marked by black veins. The scene provides a stark parallel to the fortress: both are sites where living beings and military technology have been fused, but the city can be imagined as a refuge while the child inside the machine exposes the violence hidden within such systems. The Holy City’s mobility thus carries an unresolved question about whether technology serves the people enclosed within it or turns them into components of a weapon.

From Sanctuary to Political Future

The airborne city’s proposed relocation anticipates the broader political reordering of the story. Jack later appeals to imperial citizens by offering surrender and humane treatment in the Cordelica Democracy, while Selfia frames humanity’s survival as requiring an attack against the demonspawn. These competing declarations show the same crisis being translated into different political languages: resistance, surrender, refuge, and collective survival. The Holy City Flying Fortress stands at the center of that struggle because it makes displacement visible and negotiable.

Its ultimate significance lies in the tension between sacred continuity and historical rupture. The Holy City carries its patron’s image and the memory of the Theocracy, yet its ascent removes it from the ground that defined its former national existence. It can be analyzed by the Empire, retained by its defenders, or transformed into a neutral free city. In each possibility, the fortress preserves a remnant while forcing that remnant to become something new: not simply a city that escaped destruction, but a mobile political and technological sanctuary whose future depends on whether rescue can avoid becoming possession.
