Marseille is an unspoiled oceanic paradise, with no landmass rising over 12 meters above sea level. The climate on the Planet is relatively mild, with polar regions only slightly cooler than the equatorial regions that receive most of the sunlight. The thick atmosphere and deep oceans are in constant motion, forming an immensely complex hydrologic cycle that contributes to the unique climatic conditions. The Planet's Ocean life is abundant, with numerous species unlike any other organic life forms found elsewhere in Sirius. Creatures similar to Earth's echinoderms are very widespread in the upper oceanic layers. Several species of that group contain the symbiotic bacteria that generate the substance from which a powerful stimulant called Nox is derived. The bacteria extracted from their hosts are shipped to drug laboratories in frozen form, which is the only way pure Nox can be extracted. Attempts to cultivate these bacteria in space or on other Planets have all failed. The bacteria cannot survive for long without their hosts, and symbiotic echinoderms require a very complex environment to live in throughout their life cycle.
Marseille is possibly the only Planet in Gallia that was colonized earlier than the Crown sanctioned. Several ocean platforms were set up before the government greenlit construction of permanent oceanic settlements. Not much is known about whom those communities belong to, and despite attempts to dismantle them by the Gallic Royal Police, they continue to thrive, mostly below the surface of the ocean. In 619 AGS, the first legal resort platforms appeared planetside. The Planet was initially designed to serve as a high class resort with high prices and even higher quality standards, with massive city-sized ocean liners moving from island to island. Most Gallic nobles consider Marseille their number one choice as a resort destination. While it was never officialy confirmed, it is rumored that Gallic monarchs themselves visited Marseille incognito multiple times.
Marseille is home to over four dozen resort settlements on the few suitable larger islands. This is not a large number compared to some of the other resort Planets, but on Marseille they were intended to be large and versatile, providing multiple types of entertainment concentrated in a single place. The Planet is also home to a large shipyard that produces Cruise Liners, Yachts, and a wide variety of service Ships necessary to ensure safe and reliable operation of the Planet's facilities. While safety and comfort are the number one priority for companies in charge of operating Marseille's resorts, Junkers, Unione Corse, and other "undesirable" elements frequent some of the planet's spaceports, raising concern about the actual safety of vacationing on Marseille. Nevertheless, the immense popularity and reputation of the planet draws in thousands, and the planet averages between 150.000 and 250.000 people officially. A census of the "sunken cities" as the illegal platforms are called, has never been taken.
In 826 A.S., an immense space battle was fought in orbit of the planet between Royalist and Council forces, barely won by the royalist power. Both fleets were ground down, leaving numerous debris in orbit of the planet, and ultimately both powers withdrew.The scars and aftermath of the battle lingered, while debris from the Oblique infell onto the islands and caused untold damage and dead, while the planet reeled under political turmoil caused by the power void left when GRN forces abandoned Provence. An attempt made by the local government to restablish rule of law was ultimately capitalized by political elements from control the sunken cities, mostly from the Union Corse.
