The Shining City, where the Princes of Hansa have sat for 4 centuries is a work of art, in which generations of Princes have built villas, palaces and temples rivaling each other in opulence and splendor.
Diamantea initially stood on a small island in the Dark Sea, intended only as a palace where the Princes could meet in a territory neutral to their disputes. The city grew rapidly; first with the palaces of the princes themselves, then with shops and services for the benefit of the nobles and their entourage, and then grew out of all proportion when, whoever had enough money and interests to be in the place where political decisions are made, made Diamantea the his house.
Currently the island of Diamantea is completely built up, but new houses and buildings are built on land brought out from the water, on stilts or artificial foundations. The Guild of Laborers has become very powerful and also receives subsidies from the Princes themselves, as in addition to dealing with the construction of new homes it also maintains magicians with the specific task of erecting a barrier that protects the city in the event of storms or sea storms. It is said that the city guard has its own group of wizards to employ in case the Laborers are unable to cope with an event that is too devastating.
