São Ricardo

São Ricardo, officially the State of São Ricardo, is an insular state of Cartadania. It is the northernmost island group in the Urlazio Sea, occupying an archipelago in the confluence of the Odoneru Ocean and the Urlazio Sea, and is one of two states to be composed completely of islands, the other being Porta Bianca.

The state encompasses nearly the entire volcanic Esalva archipelago, which comprises five large islands and numerous smaller ones spread over 65000 km2 of land and sea. At the northern end of the archipelago, the five main islands are—in order counterclockwise from northeast to southeast: Rey, Maceres, Gravarre, the island of São Ricardo, and Graciosa. The island of São Ricardo is the largest island in the group; it is often called the "Big Island" or "Esalva Island" to avoid confusion with the state or archipelago. The archipelago is physiographically and ethnologically part of the Luson subregion of Sarpedon.

São Ricardo's diverse natural scenery, warm tropical climate, abundance of public beaches, oceanic surroundings, and active volcanoes make it a popular destination for tourists, surfers, biologists, and volcanologists. São Ricardo has over 8 million permanent residents, along with many visitors and military personnel. Its capital is Lua on the island of São Ricardo.

São Ricardo is the 25th-largest and the 16th-most populous, as well as the 8th-most densely populated of the thirty-one states. The state's coastline is about 1,800 miles (2,900 km) long, one of the longest in Cartadania.
