I remember reading a trilogy of books during the '80s or '90s. I was in the USA and the books were in English. The first had the appearance of pure fantasy (and I thought it was). The second shifted pretty seamlessly to science fantasy. In the third you realized the whole story had been science fiction.
Half-remembered details include
- the world being transformed or terraformed, though it was habitable to begin with
- people were transformed too. All men became horny, handsome, ripped hunks, while the women became over-boobed, horny bimbos. I say that because the transformation affected their minds too, not as an insult. Even though their minds were affected, they could still strive to and succeed in think(ing) normally and rationally. ... This will sound weird, but I don't think this plot point came off as farcical.
- two types of mages: those who could change matter and those who would use illusions. The illusionists might have been considered the more powerful.
- a realm of heavy mist or fog. The illusionists may have been strongest when there.
- one of the lead females unexpectedly gaining male genitalia. I think she eventually became an over-boobed bimbo too. Eventually I think she became fully female again. Oh!! -- I think it was a switch! A guy got her crotch, and she got his.
- the author may have been pretty prolific at the time (multiple books per year)
(response to "duplicate" notice)
- The series Soul Rider is indeed the short answer to both questions.
- The original question, however, provides only background information (so far as I could tell) for the first 3 volumes -- written and published as a trilogy. Instead the question apparently concerns itself with volumes 4 and 5, which was/were prequel story(ies) published after the trilogy. From book summaries, they are science fiction telling of an interstellar human civilization and how it eventually came to found a colony on an isolated planet and begin terraforming it. The question describes them losing track of technology.
- The events in item 2 probably predate the trilogy by hundreds or thousands of years, with different characters. The first volume of the trilogy, where my question begins, appears as a fantasy story about a medieval civilization with magic. Over the course of the trilogy you learn more about the world, and by the third volume you realize that it has been a science fiction story all along.
The questions are completely different, describing different things. But if it is common practice in SF&F to declare::link as duplicates such questions if they have the same answer, I have no objection. Hopefully the linkage will go both ways though, so people with knowledge only of the trilogy can know about the prequels, and people who know only about the prequels can find the trilogy.
- Q1: I'm looking for a series of movies about a little boy who rides a flying speed racer. He grows up, makes friends, has adventures, and fights a lot of people. He doesn't like sand. I think he yells near the end, like he was really sad or something. But maybe he didn't.
- Q2: I'm looking for a series of movies, a trilogy I think, about a teenage boy. He meets some robots and an old guy, and then his parents are killed by some bad guys. He makes more friends, has adventures, and fights a lot of people. One of the bad guys can't breathe very well and wears a big helmet. Now he says he's the kid's father. In the end there is a big fight, and they blow up the really big spaceship of the bad guys. Then they do it again, this time with help from a bunch of teddy bears.
- Once they have answers, are Q1 and Q2 duplicates?
