Puerto Plato is a (noncanonical) Castillian trade port at the gateway to (my noncanonical version of) the Midnight Archipelago. Almost all
Archipelagan traffic came through this port before the Castillian invasion of Montaigne, but since the Castille/Montaigne War, there has been little
communication between the bustling trade city and the Castillian government. It is fairly well known as a free-town with only modest lip-service paid to the
Admiral Orduño is known to have vowed to take justice to Puerto Plato by bringing Governor Cordoba's head to Castille, and bringing the city back under King Sandoval's authority.
Of course, the war with Montaigne is of much greater import to Admiral Orduño at the moment.
The city of Puerto Plato is the only city on the island of Puerto Plato. As such, it is a very, very big city. Both are named for the extensive silver veins riddling the island's three central mountains. The three mine systems (Las Minas de los Arboles Negras, Las Minas de la Montaña de Plato, and Las Minas de los Trece Caminos.) Are on varying sides of the mountain range, and have small shanty towns that connect to them (Arbola Negra, Montaña de Plato, and Trece Caminos) where the various workers are housed.
El Mercado de Sol is the central marketplace of Puerto Plato, and an important trade conduit between the Archipelago and the continent. Unfortunately for prisoners throughout the Archipelago, Governor Cordoba has refused to stop the growing slave trade in the Mercado. Of course, Governor Cordoba has refused to put a stop to any illicit activities on his island, leading to a freewheeling society somewhat like Trague's Freiburg, but without the tempering influences of the Rose and Cross, the Wachhunde, and the Freiburg Guardsmen. As a result, Puerto Plato is also well known as a free port for pirates, as long as the Castillian Navy is not around.
Puerto Plato is not, however, a disorderly city. While organized crime is very much allowed, the casual criminal or troublemaker is sure to buy a quick trip to the slave auction. Puerto Plato's motto seems to be "Disorder is Bad for Business" and you won't find any place that enforces this idea more stringently. If you're a pirate, you won't find any trouble in Puerto Plato until someone in your crew starts a bar fight, then you'll have a meeting with the Governor's men, Manzo's men, and representatives from concerned nobles all over the city. If you prove unwilling to listen to reason, Puerto Plato is more than capable of defending its own business interests.
