Maintenance Veins
Narrow single-file service tunnels threading through the walls of District 5's operational layer. Barely wide enough for one person, unlit beyond minimal emergency strips, connecting junctions through routes that do not appear on any player-facing map.
Used for stash locations, escape routing, and movement that benefits from nobody being able to follow without already knowing the route. Players use them when they need to disappear quickly from a junction they entered too visibly. Khuyeta Shavki move through them without speaking.
