Iron Choir Relay Berth Shelter Watch Model

A berth shelter is a room carried in a bundle, and this one expects the room to be cold, sharp, and filthy. The build combines aramid weave, titanium hardware, fluorosilicone seals, and vacuum-rated aerogel; this iron choir version adds ribbed metalwork that rings when a fitting seats. Relay connections accept a buddy line without disconnecting the primary system. The watch model favors endurance and readable telltales over speed. Crew pull the corner tapes, lock the hoop sections, and connect bottled air at the guarded manifold. The vestibule is cramped on purpose: less volume means less gas wasted each time a casualty comes through. Pack it damp and the folds freeze together; deploy it over a jagged deck and the floor loses the argument.
