Starship & Tech

The ship he lives on, the rig he flies, and the three tech rules the fiction never breaks. All invented — documented here like an engineering brief.

The Starhold Vigil — engineering brief (in-fiction)

• Class: converted long-haul tender, rapid-response refit. Third hull of the name.
• Role: StarTeam’s flagship, mobile base, and Cass’s home — part rescue station, part workshop, part barracks.
• EVA bay: four airlocks, suit maintenance shop (Petra’s domain), the patch wall, and the ready-rack where Cass’s Longhaul lives between ops.
• Docking cradles: built for catching things — the ship is designed around recovery, with Jinx’s shuttle Second Guess and two interceptors.
• Sensor grid: the hull-mounted array Cass babysat for seventy-two hours during the Long Dark — the ship’s eyes, and the reason the storm nearly blinded it.
• Age: old, by the fiction’s standards, and proud of it. The Vigil’s quirks are crew knowledge: which airlock cycles slow, which corridor loses gravity in a turn, where the recycler’s stew is least terrible.

The Driftline rig — engineering brief (in-fiction)

• Type: precision maneuvering backpack for free-flight EVA.
• Propulsion: RCS quads, hot-tuned on Cass’s unit — faster response, less forgiveness.
• Endurance: roughly forty minutes of aggressive maneuvering; the Driftline Run spent nearly all of it.
• Control: dual hand-controllers, fine-feather inputs; the lore’s phrase is “think it, feather it.”
• Failure modes: the ones Cass has flown through — partial thrust, single-quad out, propellant imbalance — are the reason the dead-stick recoveries in his record exist.
• Name origin: the “driftline,” Rin’s plotted intercept path — the rig is named for the math, not the machine.

The AEGIS suit line (in-fiction)

The Mark VII “Longhaul” is the seventh generation of the fiction’s AEGIS EVA line. Earlier marks appear in the lore as history: the Mark IV work suits of the Kestrel era (what Cass wore at eighteen — borrowed, too big), the Mark V cadet rigs, the Mark VI that the Longhaul replaced. The design throughline the fiction insists on: each generation gets tougher and simpler, because vacuum punishes complexity. Cass’s unit, the first Mark VII off the line, is the thesis made personal.

The three tech rules

The writers hold three rules across all the fiction, and this page states them so readers can check the lore against them:

1. Vacuum is honest. No shielding MacGuffins, no magic fields — pressure, temperature, and radiation behave like physics says. Drama comes from preparation and margins, not from the rules bending.
2. The suit is a machine with limits. Air, power, coolant, propellant — every op in the archive is a budget, and the budgets are visible. The Silent Array ends at 6% suit power because the numbers said so.
3. Tools don’t save people; people do. The tech enables the rescue; the decision, the discipline, and the nerve complete it. The fiction never lets a gadget be the hero — that’s Cass’s job.

Comms and telemetry

The invisible tech: Theo’s boards — suit telemetry streamed live to the Vigil on every EVA, the hot mic, the abort criteria coded as numbers so they can’t be argued with mid-op. The SC 1212 cadet self-rescue is the lore’s monument to this layer: forty minutes of radio, no heroics, one talk-through, one life. The fiction’s thesis is that the most advanced technology on the ship is the crew’s trust in the checklist.

The kit Cass won’t fly without

Beyond the suit and the rig, the fiction names the personal kit — the things that live in the Longhaul’s thigh pocket and go outside on every op:

• The carabiner — oversized, one-hand operable in gauntlets. Clipped first, unclipped last. The signature object.
• The patch kit — soft seals, clamps, bladder patches. The reason “soft seal” is in the Glossary and the Kestrel is in the Timeline.
• The rescue ball — inflatable single-person sphere (a real NASA concept, borrowed into the fiction). Never used. Carried anyway. The lore’s perfect emblem of the doctrine: prepare for the emergency you plan never to have.
• The checklist tablet — Theo’s mirror copy on the boards, Cass’s copy on the chest. Run twice. The bravest thing he owns.

The throughline the fiction insists on: none of this is heroic. It’s inventory — the boring, checkable, countable stuff that makes the heroic parts survivable. “Slow is smooth, smooth is sealed” isn’t a motto; it’s what the kit list is for.
