Main Harbor image - Silverate DEVs

The main harbor of the Capital has two towers which raise a thick steel chain at dusk to prevent ships from entering during the night and lower them at dawn. The whole harbour as the city itself is encircled by high walls.
There are many warehouses and shops selling various products from around the world. The harbor is also a place where inhabitants of the city may take a walk and enjoy the beautyful sunsets especially at early autumn and late spring.
The lighthouse is on a small island just outside the harbor and has a big magical crystal which emits light visible miles away from the harbor itself.

Also I showed only two stone docks but in reality there would be dozens of them.
