A Void passport is a civic identity booklet that allows a registered resident to cross signal districts, border gates, and approved routes beyond Nullhaven.
Design
The standard booklet has a pale green cover, a black verification eye, and a machine-readable line made from the resident's public name. The inside page records a profile type instead of requiring every resident to have a human face.
Emergency signal stamps are added for routes known to vanish during severe weather. A stamp glows when the nearest border gate still recognizes the document.
Passport classes
The four common classes are standard resident, interspace transit, science field, and press correspondent. Field and press passports allow equipment to cross customs when it is listed before departure.
Use and renewal
Passports are inspected at border gates, Platform Zero, and the final marked exit of Starlight Highway. Renewal is normally required after five signal years or after a permanent change of name or resident form.
