Knarrheim

Every other Solar System capital was built to be one. Knarrheim was built to haul ice, and only stopped moving because it turned out to be more useful staying still.

Knarrheim — "ice-home," a name its own registry logs treat as more description than title — began as the Nordstjerne, the largest hauler-mothership in the Knarr Line's founding fleet, and has not moved under its own power in over four centuries. What started as a single ship's hull, docked semi-permanently at a rich claim cluster to serve as a forward depot, accreted refinery modules, habitat rings, and berthing bays across five hundred years of continuous use until the original hull became structurally incidental to what the station actually is: the Knarr Line's largest permanent population centre, and the usual meeting ground of the Thing when enough delegate ships can reach it at once.

The Old Hull

The Nordstjerne's original pressure hull is still there, load-bearing and in active use, at the structural centre of everything built around it since — Line engineers maintain it under the same standing order that has applied for three centuries: repair in kind, replace nothing that doesn't have to be replaced. Newer arrivals touring the station for the first time are reliably surprised to learn the oldest section is also the most heavily reinforced, not the most fragile; the crews who keep it running take a certain pride in visitors assuming the opposite.

The Thing Hall

Knarrheim's largest single interior space was not part of the original ship at all — it was cut into the hull generations later, specifically to give the Thing somewhere large enough to convene delegates from every Line-chartered habitat at once without borrowing space from a working refinery bay. Delegates still enter by rank of registered tonnage rather than any formal precedence, a seating custom nobody has bothered to make official because nobody disputes it. The hall's walls carry a running, hand-added tally of every habitat ever chartered into the Line, updated by whichever delegation last had reason to add to it — an informal record the Solar System Defence Command's own archivists have quietly come to treat as more reliable than the Line's official registry, since nobody has ever caught it being altered after the fact.

Life Aboard

Knarrheim runs closer to a working port town than a research platform or a habitat in the Orbital Habitats Compact's Earth-orbit sense — refinery shifts, convoy departures, and berthing schedules set the station's actual rhythm far more than any civic calendar does. Norwegian and Danish share working-language status in most public signage, with Icelandic used in the older residential rings whose founding families never fully switched away from it. The station keeps a version of the old knarr-crew storytelling tradition alive in its common berths, and a long transit-season arrival is still, as often as not, marked with one.
