The Worlds of Light: Lux and Lucis

After the initial start of the colonization of Eden, other planets in the Alpha Centauri system were being explored for terraforming. The binary planets, now called Lux and Lucis, seemed to be viable candidates. Domes were constructed on the surfaces of both planets, which made the terraforming process much more controlled. When the mistakes made on Eden became apparent, Lux and Lucis were still very well managed and the colonizing process just went on more carefully, especially for Lux.


Lux is the bigger planet of the two, with an air pressure similar to earth (though not breathable), and many temperature zones that could sustain earth-like life. And just like Eden, it already did harbor life forms. Countless different bacteria, weird-looking plants and colorful snake-like creatures inhabited the planet. First, domes were places on the surface of Lux, but after some experimentation, people discovered that oxygen masks could suffice, and terraforming continued outside of the domes.

After the fiasco of the terraforming on Eden, the settlement of the much less habitable planet Lux was done more carefully. With more work to be done than on Eden, the terraforming is much slower, but also much more controlled. Every new species to be introduced is first tested in domed ecosystems on Lux’ smaller sister planet, Lucis. As well as the environment, every aspect of life on Lux is strongly controlled, stable, and thoroughly tested before any changes are made.

The colony on Lux was being directed to achieve perfection, being the next best candidate for population in an earth-like fashion. The colony became extremely heavily controlled, no creature or material was allowed on the surface of Lux before extensive testing in the ecodomes on Lucis, and an decontamination phase. Where needed, species were genetically altered to fit the environment. For virtually every species on Lux the populations were strictly monitored and breeding programs were created to keep the populations stable and genetically healthy. After a while, this also applied to the humans living on Lux. As soon as people had left the domes to go live on the surface of the planet, interest of settlers from anywhere became great; anyone wanted to live on Lux. But because of the delicate ecosystem, an extensive admittance program was put in place, allowing in only a few settlers each year. And since there could only be a few selected, the best ones were picked out based on their genetics. Of course, the matrons and patrons from Lucis kept a close watch on the populace of Lux, and they decided that they should put their data to good use, and created a breeding program for the humans as well,ensuring the best possible offspring. 

People from Lux are practically perfect; they are healthy and beautiful. They live in beautifully constructed cities and villages of sleek, cream-colored stone, and due to the utmost balance of the planet, they always have enough food and materials. People dress is beautiful flowing clothes, very colorful and richly embroidered, often made from thin, shimmering and gauzy materials.

The approximately 30 million colonists prefer the stability created by their society; there is a standard of living unmatched in most settlements, either in Alpha Centauri or around Sol. Regular human beings are practically never allowed on Lux, and people from Lux can only leave their planet with permission from population control on Lucis, and often accompanied by a matron or patron from Lucis.


Lucis is the smaller planet of the two, and has a rather thin atmosphere and lower gravity than Lux.  In many aspects, Lucis is comparable to Luna. It is barren and mountainous, but unlike the moon it does have tectonic activity.

Lucis is currently used to test changes to the ecology of Lux. Massive ecodomes recreate parts of the Lux ecology to test the introduction of new species of plant and animal. Laboraties on Lucis genetically modify species to survive in the present atmosphere, as well as serve the human colonists better. The Lucis regolith is also harvested to refine helium-3 for use in fusion reactors on Lucis and Lux. An automated launch system drop resource pods filled with regolith on a special landing ground on Lux.

People from Lucis are often scientists, working in the extensive research labs designed to support the societies on Lux. They usually wear lab coats and lab clothing.

There are approximately 3 million people living and working in the labs and ecodomes on Lucis. Construction of a space elevator has started in 2173 and is mostly completed at present.
