Derivation of name: Latin for “fair” (fair weather), with feminine suffix
Serena is a tide-locked habitable planet that is home to the colonies of the Serenese Federation. The world was a Mesogaian world with a nitrogen, carbon dioxide and methane atmosphere, but the Hygiea Mining Corporation illegally initiated the terraforming of the world into a Eugaian world. By the time the terraforming was discovered, the fragile lifeforms of the world were losing their battle against the introduced terrestrial lifeforms, and it was too late to restore the biosphere to its pristine state. After the Hygiea Mining Corporation received the corporate death penalty, Asteroid and Lunar Limited purchased the rights to the system and after a lengthy investigation received permission to complete the terraforming on condition that as much native life was preserved as possible.
Some of the native organisms proved to be more resilient than originally thought. Some of the native life adjusted to the terrestrial lifeforms and oxygen atmosphere, and the oceans of Serena contain a unique mix of native and terrestrial lifeforms. Proponents of the settlement of lifebearing worlds use Serena as an example of how native life can adjust to the influx of terrestrial organisms. Opponents point out that most native life on Serena has not survived the terraforming, and not all lifeforms would be as compatible with terrestrial life as the life on Serena.
The land area of Serena is divided into the following major land masses:
Serena has a thick atmosphere, more than twice as thick as the Earth’s atmosphere. The sky colour of Serena is greenish, due to the thick atmosphere and redness of the local sun.

Derivation of name: Latin for “rock” (stone), with feminine suffix
Saxa is a small Arean world with no appreciable atmosphere. Mineral prospecting has revealed deposits of useful minerals. The world is currently being mined by crawlers in a joint venture between the government of the Serenese Federation and the mining company Asteroid and Lunar Resources Limited.

Derivation of name: Latin for “frosty”, with feminine suffix
Despite its name, Gelida is actually a Europan-class world with a subsurface ocean under a thick crust of ice. It is an unusually large world of this kind, having a radius slightly larger than the Earth. It has a thick atmosphere.

Derivation of name: Latin for “fourth”
Quartus is a Gelidan-class world, with a thick covering of ice covering a rocky mantle and small metallic core.

Derivation of name: Latin for “mild”
Mitis is a gas giant of the Eujovian type with a mass about 3/4 the mass of Jupiter. It is a real planet, the discovery of which was announced in 2008 when it was known as Gliese 832 b[1] (although all details presented here are fictional). It has a faint ring and a system of moons that are whimsically named after pet dogs belonging to various astronomers.
The planet has a number of nicknames. It is also known as Muttis because its moons are named after dogs, as The Mighty One because it is by far the largest planet in its system, and even The Mutty One.

Derivation of name: Latin for “strangeness”, in reference to its eccentric orbit and large axial tilt
Novitas is a Cryojovian world very similar to Neptune. The world has several odd features. It has a large axial tilt, an eccentric orbit and its largest moon, Ginger, is larger than Mars. It also possesses a pair of narrow rings.
