Young Caela was able to adjust and thrive because she was tuned in to herself, to her own perceptions and power. Her parents, Lev and Letta, they exist within her, but so does all that psychic energy moving through her. To make use and sense of that, she needs integrate experiential impressions, integrating a trusted sense of self.
How moderate can temperatures be? Do we have the ranges we do have because of some specificity of size or shape or orbit and distance form our Sun? I'm not picturing Winter on Eden, despite its frigid everpresent reality for me here and now on Earth. Fall I can see, the harvest season. But why not several harvests like in the sunny warm states? Out in the farm areas beyond the city's structures, they have greenhouses, even hydroponic technologies from the ship. Even if the planet has a variety of climate zones, they may have settled in an area less likely to freeze. Would it be sweltering in the Summer in the city? They would know how to build for minimizing that, design to encourage cooling winds, maybe have air conditioning. They would plant trees according to ecologically thought out plans for shade and water retention and air cleaning. The cultural norms would include a slowness of outdoor perambulations, light-weaved clothing. I see bright colors, even in the enclosed atmosphere of the built-up city. There is an appreciation for art, culture, color, design. It's not that they don't enjoy diversity. They are worried, frightened, that they will be left behind, out-classed, unable to successfully excel in competition for what they think to be scarce resources, even such nonmaterial resources as public appreciation and prestige, as well as whatever passes for wealth in their culture. They have closed themselves in to this city. Those of true valor and adventure have gone off exploring. Those who can't abide fences and rules have been sent to the outer reaches to work out their destinies as farm labor or defense trainees or bucolic eccentrics.
People jammed together with their secret inadequacies and fears can build up a psychological squalor. People who present as clean, upright, hard-working citizens can be harboring petty and grand mal demons who rule over their potential better natures and insist on penance without respite, respect or concern. The empaths are not immune from demons, though are to some extent insulated from personal devolution by their mutuality of feelings, the ability to if they so choose never be alone. They will be able to take advantage of distance from the closed in city to develop a culture of their own design. Thesis, antithesis, synthesis. The dialectic of socially evolving mankind prevails. This is not a story about man against nature or man as part of nature, but about human nature; but we are not alone in the Universe. There is no clear division of background and foreground. The picture includes waves and landscape and sky and all the rest, as far, as near, as detailed, as the artist bothers to render; as the eye bothers to see. All I can do is look deeply into the crystalline vision, and respect, describe, reflect my impressions, my perceptions, my emotions and their creations.
