The Lucida system, sometimes referred by its star's original nickname, the Iota system, is a star system with 6 major planets and 14 dwarf planets, as well as two asteroid belts. Historically, it is referred to as variously, such as Iota Piscium, Iota, and Corona, some of the names are still in use, even today. The system gave its name to the Iota Network and its ruling archailect, the Iota Scholar.

The system's many polities have a history of becoming major players in interstellar politics. The most notable of these is Corona, once the capital of the Taurus Nexus, a superpower of its time, although most other major polities in the system have also influenced other nearby star systems at some point, especially after the system became the center and the symbolic capital of the Iota Network.

Minerva is the first planet of the Iota system. It is a EuCytherean planet, not much larger than the Old Earth, with an atmosphere dense enough to create an ocean of supercritical carbon dioxide several kilometers thick. The planet's albedo is enhanced due to the feral weather machines, descendants of those introduced since the early days of colonization. The planet does not have a natural satellite, and even today there is little artificial infrastructure in orbit around this world, apart from a few rotating skyhooks at the equator.

Originally Minerva was part of the budding Hera Federation, but broke away during the Ex-MPA territory rush period. As gengineering technology evolved, the colonists soon opted for floater tweak bodies, allowing them to live outside floating habitats. Over thousands of years since then, the Minervan society evolved into a remarkably static empathic tribemind-based society that interacted very little with its off-world neighbors- a status that they maintained for over seven millennia, interrupted only by the brief occupation by the Solar Dominion, when they were forced out of isolation.

Today, the people of Minerva are much less strict about their isolationist policies. Many Minervans chose to join the wider Iotan community, and some even migrated away from their homeworld completely. Those who remain continue to pursue collective well-being in their own traditional, spiritual way. Many Iotans think that Minervan culture is constrained and even boring, but most of the 521 million people who populate this world have chosen to reject the high-pressure, materialistic culture that they see as plaguing the rest of the system.

Eva has numerous arcologies on its surface, which support most of the population of this world
EvaType - Selenian.
Radius 5179.2km
Semi-major axis 1.241 AU
Orbital Period 1.289 standard years
Rotation period 34.363 standard hours
Eva is the second planet of the Iota system. It is a hot Earth-sized EuArean planet. Its surface is very heavily cratered, including many massive craters such as the New Caloris crater (where the planet's honorary capital Mirakis is located), although the planet's thin carbon dioxide atmosphere slowly erode many of the craters away. Several dozen gigantic dark-colored city-domes dotted the surface, some for aioids and vecs, and some for bionts and cyborgs. The planet does not have any natural satellite.

Throughout early history, it monopolized amat production in the system and was on-par economically and militarily with Hera, the strongest polity at the time. This monopoly collapsed with the creation of monopoles, bringing along with it a good chunk of the planet's economy. The planet was a minor member of the Taurus Nexus. It never officially joined the NoCoZo, remaining de jure independent throughout the era. It was then annexed by the Solar Dominion along with the rest of the system and finally joined the Iota Network.

Historically, Eva has been one of the most expansionist polities in its system. This mentality never faded away and currently takes the form of a campaign to export its cultures. It has been rather successful, and the unique optimistic Evan culture became popular among many polities throughout the Iota system and beyond.

Corona in the Current Era, with its artificial rings and auroral display
CoronaType - Terraformed Gaian world: see also main article about this world.
Radius 7637km
Mass 1.67 x Earth
Semi-major axis 1.816 AU
Orbital Period 2.282 standard years
Rotation period 19.38 standard hours

L5: Kayal Swarm
Polities: - Planetary State of Corona
Corona is the former capital of the Taurus Nexus, and a major Academic World. The world has been part of the NoCoZo and the Solar Dominion, but is currently independent. Since 6035 the ruling body of this world has been the Planetary State of Corona. The world is surrounded by numerous habitats known as the High Cyclers, and also by a system of orbital rings which are capable of displaying artificial aurorae (amongst other display options).

Polities: - Federation of Hestia
The Hestia Sunline is a circumplanetary light source supported by a pair of counter-rotating orbital rings; these rings are powered by the fusion of hydrogen and helium extracted from Hestia's atmosphere, and the same source of energy provides illumination for the moons and habitats orbiting this world. Both Oikos and Prytania are tidally locked moons, and half of each moon facing Hestia has been paraterraformed with a worldhouse roof, allowing them to maintain a temperate environment on that hemisphere.
