Doors and walls in Starfall are the lines between “ours” and “theirs,” “breathable” and “deadly.” They’re not just scenery—they’re pressure seals, class markers, and weapons in slow motion.
Every door is an argument about trust. Inner Sphere arcology doors are smooth transparent aluminum slabs that iris open when your ID pings the local net; in slum levels and Outer Sphere rigs, they’re dented steel plates or plastic sheets that grind on misaligned tracks and stick when the gravity fluctuates.
Walls and doors pull double duty:
Pressure and atmosphere: A “door” might be the only thing keeping a hab corridor from the raw Rift‑oxide atmosphere of a mining shaft or the vacuum outside a station’s hull. That’s why airlock‑grade doors have the highest hardness and HP—you aren’t supposed to brute‑force your way through without serious tools.
Security and class: Syndicate strongrooms use steel or transparent aluminum doors over reinforced masonry or starship‑interior walls; refugee stacks make do with warped plastic partitions that a determined shove can splinter.
Territorial lines: Who controls which doors (and who has the override codes) says more about who rules a district than any map.
Automatic doors in glossy Accord or Commission facilities track you with cameras and Devotion‑aware heuristics; cheap aftermarket locks buzz when someone tries to spoof an ID chip, but black‑market techs know every bypass routine and hardware exploit in circulation.
