A passport is needed to cross borders. According to findings also the Obscure World has the need for passports.
Between the beginning of 2000 and May 2001, residents of our world who obtained Obscure Citizenship through the club Lumière sur les Cités received a superb official document. See also Motoaviette.
Another obscure passport is found by Mitya Suchin. He found a leather passport cover of Brüsel. The cover has the right size for an European passport.
In April 2015, Stephan Smith received another passport found by Mitya Suchin. It seems to be an Urbicande passeport for strangers.
