Grandbridge is the largest and most central district of Oppara, just north of the Westport and Eastport districts. Grandbridge is a mercantile district with a lot of warehouses, factories, shopping squares, open-air markets, currency exchanges, and import/export businesses. A large open square is located at the point where the district touches the Porthmos River and the Grand Bridge of the Empire is based. On most days, the square is filled with makeshift stalls, tables, and tents. This is the famous Gray Market of Oppara.
