Overland route guides for vehicle travel through remote terrain across a recognizably North American continent. No people, no borders, no services. The tone is field-manual practical: specification without judgment, no emotional register. Instrument interference zones near Founderia infrastructure. Impassable areas that are never explained. The geographic connective tissue between all the other sites.
Passport Overland is part of the Founderia universe — an interconnected fictional world spread across multiple independent websites.
