In the rule 2.6 Universe, change the current text which reads:

Each Adventurer has a “Location” , which is tracked in the GNDT. Locations are limited to real-life (i.e., not fictional or mythical), existent (as of the Reference Time) locations on Earth that have their own article in the Reference Source, and have a size or area, as specified in the Reference Source, of no more than one thousand square miles. For example, Independence Hall (United States), Elvis’ Pink Cadillac, and New York City are all legitimate Locations; while Narnia, Heaven, Asia and the Library of Alexandria do not exist as legitimate Locations.

to read instead:

Each Adventurer has a “Location” , which is tracked in the GNDT. Locations are limited to real-life (i.e., not fictional or mythical), existent (as of the Reference Time) locations on Earth that have their own article in the Reference Source, and have a size or area, as specified in the Reference Source, of no more than one thousand square miles, providing that no dimension of the location exceed 1,000 miles. For example, Independence Hall (United States), Elvis’ Pink Cadillac, and New York City are all legitimate Locations; while Narnia, Heaven, the Prime Meridian, Asia and the Library of Alexandria do not exist as legitimate Locations.
