Bergtor

GJ 505A | K2V | west_reach

Bergtor — German for "mountain gate" — is a heavy extraction system at the end of the corridor spur coming off Eisentor (GJ 3454). The name is practical: the primary habitable body's surface is dominated by elevated rocky massifs whose mineral composition drew the wave_3 founding consortium here and has kept a working population in place for three hundred years. The K2V primary offers moderate stellar conditions, adequate but not generous, and most of the habitable surface runs cold. The wealth is underground. The people who know Bergtor best know it in terms of rock.

The primary world, called Bergmass in the survey records and shortened to Mass by residents, is a high-density rocky world with thick crust and unusually concentrated deposits of tungsten, molybdenum, and the high-temperature refractory ceramics that precision manufacturing processes at every tier of the corridor economy require. The concentration is the result of the system's formation history — Mass assembled from the inner debris of a volatile-depleted protoplanetary disk, leaving behind the heavy elements stripped of the lighter material that would have made the surface habitable in a conventional sense. What resulted is a world that is cold, thin-atmosphered, and geologically inert enough to mine without constant seismic interference. The founding consortium's geologists described this combination as "ideal within the extractive specialty."

MVG's contracts have been active in Bergtor for approximately two hundred and fifty years, running through Eisentor (GJ 3454). The primary extraction agreement covers the tungsten and molybdenum seams in the northern massif region. A secondary agreement, negotiated forty years ago, covers the refractory ceramic precursor extraction in the southern highland belt. Together these contracts represent the largest single source of high-temperature refractory materials in the outer west corridor.

Supply Dependency

Bergtor's supply dependency runs entirely through Eisentor (GJ 3454). The spur_end topology gives the system only this one commercial artery, and its spur terminus at GJ 454 sees little commercial traffic in either direction from Bergtor's perspective — GJ 454 is a dead-end quarrying system whose bulk aggregate output moves inward through Bergtor, but generates limited return traffic. Manufactured goods, food, medical supplies, and operational equipment all flow in through Eisentor. Raw and semi-processed mineral output flows back out the same way.

MVG's logistics chain manages the primary export flow: ore consolidated at Mass's surface operations is loaded onto MVG's scheduled transit and moves inward through Eisentor toward Hansestadt and the wider Reach. Independent operators handle smaller-volume specialty minerals and the refractory ceramic precursors that go to fabrication shops that do not want to buy through MVG's distribution system. These independents use the same gate schedule as MVG's freighters, which means everyone at Bergtor understands that Eisentor's gate scheduling decisions affect them directly.

The local population's food supply comes from imported cultivated stock and protein synthesis facilities operated by the residential cooperative. This is expensive. It is also non-negotiable — Mass cannot grow food at scale, and the population's survival infrastructure is a line item that the extraction cooperative treats as a structural cost of operation rather than a variable it optimizes.

Faction Notes

Bergtor's governance is formally a dual council: the extraction cooperative council, which holds authority over production and resource allocation, and the residential council, which holds authority over community services, welfare, and the regulatory standards governing work conditions underground. The dual structure was created eighty years ago after a labor action that shut down the northern massif operations for eleven weeks. The action's demands included governance representation separate from the extraction cooperative, which had previously managed the settlement as a company town under its original wave_3 charter structure. The residential council is the result. It has real authority over working conditions. It does not have authority over extraction planning, contract terms, or the question of how long MVG's contracts continue.

MVG's contract relationship with Bergtor is mediated through the extraction cooperative rather than involving the residential council, which creates a structural gap: the corporate decisions that most affect daily life in Bergtor — how fast to mine, how much to expand, whether to accept contract terms that require more workers — are made in negotiations the residential council is not party to. The extraction cooperative's council has three MVG-appointed seats under the original charter provisions. The resident-elected seats hold the majority numerically but not in terms of the information available to them.

Assembly authority is present through MVG's commercial registration framework, which requires Assembly compliance. The residential council has inquired twice about Assembly settlement rights for the permanent population, which would provide a legal basis for governance standing in external disputes. The Assembly's response both times was that the existing dual council structure satisfies the requirements for recognized settlement governance. The residential council disagrees with this interpretation.

The Compact of Westphalia's relationship with Bergtor is indirect. MVG's Assembly registration requirements formally prevent the extraction cooperative from signing the Compact's mutual recognition treaty. The residential council has no treaty-signing authority. Bergtor's workforce knows the Compact exists and regards it with sympathy, but no formal relationship is possible under the current governance structure.

Silence Topic

MVG's internal geological assessment of Mass's primary deposit zones, completed eight years ago and not shared with the extraction cooperative council's resident-elected seats, revised the projected viable extraction horizon in the northern massif downward by approximately sixty years compared to the previous assessment. The revised horizon is one hundred and ten years, not one hundred and seventy. This remains within MVG's long-term planning parameters. What it means for the population of Bergtor is that the employment basis for roughly forty percent of the current workforce will be exhausted within their working lifetimes. MVG's regional planning office has begun modelling what "decommissioning timeline" looks like for a system of this type. The residential council is planning infrastructure improvements on the assumption that the northern massif operations run another century and a half.

Narrative Hook

The people of Bergtor are building a community infrastructure intended to last for generations — on a geological resource horizon that MVG's private assessments say is half as long as the extraction cooperative's official projections claim.

Calibration Note

wave_3 at hop 7 in a spur_end position is consistent with resource-discovery founding: the advance survey identified the concentrated mineral deposits, and the founding consortium followed the survey. K2V classification is accurate to the profile. spur_end with two gates — inward to Eisentor, outward to the stub at GJ 454 — is accurate. MVG's significant contract presence is consistent with the corridor's established MVG footprint running through Eisentor and into the outer west. The dual council governance structure is a plausible result of a historical labor action creating formal representation for a population that previously lacked it.
