Some port cities have complex step quay constructions with a number of different levels, allowing ships to be unloaded at almost any time of the year, even during the lowest or highest tides. Harlon, headquarters of Hartheran Navy, has one of the most advanced and extensive step quays in the world, with multiple wharfs, cranes and other dockside machinery, enabling continuous operation in all but the most extreme weather.
