Europa

One of the four Galilean moons of Jupiter, and one of the most important worlds of the Iron Pact. It has been successfully terraformed into one of Solar System's premiere water world, with the Iron Pact working hard on turning it into Mankind's first true Agricultural World (although in this case, 'Aquacultural' would perhaps be a better description).
It is, otherwise, a largely unremarkable globe, with the smallest population of all the Galilean moons.

Geography

Europa is an Ocean Planet - an ocean (and particularly deep one) covers entirety of its surface. There is a number of small islands, however those are entirely artificial, created in order to help the local ecosystem thrive on the equally artificial shallow waters surrounding them.
As a result, their placement is mostly random, each of them typically including a handful of small islands in close proximity, with the artificial seabed in-between them. At least some of those are artificial to the point of de-facto floating through the planet's ocean, in a manner similar to the floating cities housing the European population, taking full advantage of the moon's low gravity to make such giant construction possible.

Ecosystem

Contrary to what one might expect from an Oceanic Moon acting as an Agriculture World, Europa's ecosystem is rather scarce. There is only a very limited of shallows that allow more complex biomes to develop - most of them artificial. Instead, majority of the locally-grown food isn't taken from the sea 'naturally' - instead, every of the world's floating cities is surrounded by fish (and other seafood) farms. Even if something escapes from them, chances of contaminating local ecosystems in any way are minuscule to none.

Climate

Like most Outer System worlds, this is a monoclimate world that is protected from freezing only by powerful (and artificial) greenhouse effect. One of the results of that is lack of seasons and almost no temperature amplitude (with normal temperatures, planetwide and yearly, being 14 to 16C).
Water also accumulates in the atmosphere, resulting in a close to 100% humidity, with rains being actually rather rare and usually weak. It's, in short, not a very pleasant place to live in.

Natural Resources

Europa's greatest treasures lies in its seas. Ever since the terraformation of the moon, Iron Pact has been aggressively seeding it with a variety of genetically altered plankton and algae, seeking to convert the moon into its main source of food in order to limit their dependance on shipments from the Inner System and the orbital farms.
Many species of aggresively gene-edited fishes were introduced here as well, with some of them managing to live in a world that has only a fraction of their original world's gravity.

History

Europa is one of the first places within the Jupiter Subsystem to be visited and colonized by humans, with only the outermost moon of Himalia being visited prior to it. It was at leat partially chosen due to the Jupiter Subsystem being settled by the European autocrats of the first Iron Pact - seizing the 'other' Europa was seen as a form of a propaganda move.
It was temporarily the seat of the government of the Jupiter Subsystem before it was moved to Callisto following its terraformation. Other than that, its history is mostly unremarkable, at least until the Blackout.
Once the dust settled, Europa was the first of the Galilean Moons to be terraformed, most of its population relocated to the remaining three worlds of the Pact while Europa was allowed to turn into a giant
