Overview
The Underwater Nation of Athenia, formally abbreviated TUNA in trade documents and shortened to Athenia in most subsequent records, was the polity founded under the eastern sea by the former citizens of Athena. It existed as an independent polity for a short period in the early decades of Fuhai’s existence, traded with Fuhai across a relationship that included reciprocal embassies, suffered the unexplained loss of its government over a period of months, and was annexed into Fuhai with the full consent of the citizens who remained. The annexation placed Fuhai’s resource base on a level approaching that of Echo Sprawl itself, and is the development that distinguishes Fuhai’s late history from that of every other post-The Blaze polity on the continent.
The name is preserved in the records under all three of its forms. Older sources use Athena/Athenia to mark the transition from the predecessor polity. Trade and treaty documents from the independent period use TUNA because the rail company’s freight schedule was built around acronyms. Later historians use Athenia unless they are specifically writing about the trade period.
History
Athena
The polity originally known as Athena was established to the north of what would become Fuhai. Its signature project was a pneumatic tube reaching to space, anchored at a giant spire that dominated the polity’s silhouette and that, for a period, was the tallest structure on post-Blaze Earth.
Athena’s first years were prosperous in the narrow technical sense. Its construction projects were ambitious, its workshops were productive, and its leadership under Gray was popular with the small group that had arrived alongside them. The popularity did not survive its tests. As the polity grew, its citizens were increasingly unhappy with the way Gray’s decisions were made and the way the decisions were explained.
The Fabricated God
The leadership’s response to the discontent, as the polity’s records later established, was to fabricate a god. The mechanism was a computer-generated channel through which messages purportedly from a divine source were sent to selected citizens. The messages were designed to consolidate Gray’s authority and to provide a religious frame for the leadership’s decisions.
The fabrication did not produce the cult its architects had intended. One of the recipients of the messages identified them as artificial. The recipient brought the evidence to Jane Harbinger and Marsh Horton of Fuhai, whose reputation for political seriousness had reached Athena by that point. Jane and Marsh confirmed the analysis. The information returned to Athena through channels that did not protect Gray.
The Schism
Within a short period, most of Athena’s population departed for an underwater site under the eastern sea. The choice of location was a deliberate break with the pneumatic-tube vertical and a reorientation of the polity’s identity around a different kind of engineering project: a connected network of carved chambers and pneumatic tubes through which the settlement’s residents would live, work, and move. The new polity called itself The Underwater Nation of Athenia, retaining the name’s resonance while marking the break. The formal acronym TUNA was adopted in the founding charter and was the form the rail company would later use in its freight manifests.
Gray was left without a population. The spire and the tube remained where they had been built. Gray’s subsequent movements are not in any record. The name appears in a small number of late entries and then ceases to appear.
Architecture
Athenia was built as a connected complex of interlinked tubes and carved chambers under the eastern sea. The architecture was a deliberate inversion of the corporate-tower model that Echo Sprawl uses and that Athena’s spire had partially imitated. Where Echo Sprawl stratifies its population vertically, with the elite at the top and the labor at the bottom, Athenia stratified its population by depth, with the residential chambers concentrated at depths where ambient pressure could be managed and the industrial sections at depths where it could not.
The complex grew by extension rather than by stacking. New chambers were carved as new arrivals required new space, and the connecting tubes were extended to integrate them. The model had structural limits: the settlement’s growth was bounded by the rock it could tunnel through and the pressure it could engineer against. Within those limits, Athenia’s first generation built a working underwater city in the period it took Fuhai to construct its clock tower and its early laws.
Trade with Fuhai
Athenia and Fuhai opened formal trade in the years following Athenia’s founding. The principal goods moved were lapis lazuli from Fuhai’s local deposits and a small range of finished components from Athenia’s underwater workshops. Reciprocal embassies were established in each capital for the purpose of supporting the trade. The rail network operated by Nova and Octavia was extended to the eastern shore at a junction Athenia’s tubes were engineered to meet, and the company’s freight schedule began listing TUNA-bound goods under the acronym in the same period.
The friendship between the two polities was partly historical. Marsh and Jane’s role in the exposure of Gray’s fabricated god was read by Athenia’s first generation as a deliberate political favor, and the trade relationship inherited that goodwill on terms that neither side felt the need to renegotiate. Athenia is, in the available record, the only polity of the period with which Fuhai conducted commerce on the basis of mutual recognition rather than careful distance.
The Vanishings
Athenia’s government collapsed during the period of the trade relationship. Members of its administration ceased to appear in Athenia’s own records, and then in Fuhai’s records, over a period of months. The vanishings did not present as deaths. The members did not appear in the chambers they were known to inhabit, in the meetings they had been scheduled to attend, or in the freight manifests for the lines they had been booked on. The pattern was the same across the affected members: a last day of normal activity, then absence, with no body, no note, and no further appearance.
The reason has never been satisfactorily reconstructed. The most-discussed candidates are an engineering failure at depth that the surviving record did not catch (Athenia’s earliest pressure-engineering had been done at a margin Athenia’s first generation acknowledged as thin), a coordinated act by an outside actor (the candidate most commonly named is Gray, though the evidence is circumstantial and Gray’s subsequent absence from the record is also unexplained), and a series of unrelated departures that happened to coincide. None of the candidates accounts for the totality of the pattern. The matter is, in the surviving record of the period, the largest unsolved disappearance event in post-Blaze history.
By the time the absence was understood as a pattern rather than as a series of unrelated departures, only a small number of citizens remained on the polity’s territory. The chambers were intact. The pressure systems were operating. The polity had simply ceased to be inhabited at the scale that had sustained its government.
Annexation
With the full consent of the citizens who remained, Fuhai annexed Athenia’s territory. The annexation was unopposed and was processed through Fuhai’s existing immigration and territorial provisions of the New Nation Act and the People and Places Act, rather than through a separate treaty. The lapis lazuli deposits that had been the focus of the trade relationship were incorporated into the rail company’s freight schedule under Fuhai’s freight classification, the underwater chambers were registered as a district of Fuhai under the People and Places Act, and the pressure systems were transferred to Fuhai’s engineering apparatus, where the original Athenian engineers who remained were retained as the technical staff for the district.
The combined resource base placed Fuhai on a structurally different footing from every other post-Blaze polity, and approached, in raw terms, that of Echo Sprawl itself. The annexation is the precondition for the events documented in What Marsh Did, not as their cause but as their stage: the polity Marsh would soon act to defend had become, by the annexation, a polity worth defending on a scale that the founders had not initially planned for.
Status
Athenia is, at the time of writing, a district of Fuhai rather than an independent polity. The underwater complex is still inhabited, the engineering apparatus that maintains it is operational, and the original Athenian residents who remained at the annexation continue to live in the chambers their generation built. The name Athenia is retained as the district’s formal name within Fuhai’s registry, and the acronym TUNA survives in the rail company’s freight schedule for the lines that serve the district.
