Istanbul is a Euro Britannian-occupied city and the location of the Headquarters of the Knights of St. Michael.

The city is located on the European and Asian continents, which is separated by the Bosporus Strait that runs from the Sea of Marmara to the Black Sea. Numerous large solar panels similar to those seen in other Britannian-held territories tower over the city. One of the most notable locations in the city is the Dolmabahçe Palace, which is used by the Knights of St. Michael as their Headquarters.
