For what it is worth, the sacrificial victims of the Temple of Doom are mummified and stored away in a crypt somewhere as property of Negeé. Perhaps the greater Negeemi drow might get similar treatment?
I'm not sure that it would really have been necessary to make huge secret of cloning these personages of the past. I mean, by the future era Aiers and the Nebulosa of Ots setting, cloning is legal and massively practiced, particularly in colonizing new worlds. I would say that Alice and company would not only NOT keep this a secret, they might trumpet it out to the world. Most folks would shrug their shoulders, but drow, and those people who identify themselves as being drow descendants would be very interested.
It might make for a good marketing ploy in getting the support of drow populations and getting those drow to sign up for colonizing the planet Negeé? Indeed, other corporations might dismiss the whole thing as marketing nonsense and be surprised if UTI actually did as it said?
In any case, any drow colonists would probably have the colonizing scheme marketed to them on racial and almost religious zeal, the name of the new planet makes that clear. They would need a great deal of motivation in a way, as they would be ceding most of their rights to UTI? But rebuilding a glorious past amidst the stars in the future would make for an impressive draw. Particularly when the genetic duplicates of the drow of an illustrious past might live and breathe again with the colonists someday would be very exciting!
And, of course, elves having their long lives, the pure elves anyway, the phrase of "A future you might live to see", might be especially true?
I would question if any true memories could ever be restored to clones as any genetic recording of memories is probably not true. Although history might give a sketchy background personality that might be implanted into the clones, much like any produced clone, but a bit more customized. It would hardly be the real deal, but at least the clone would act something like the original might?
Perhaps magic might bridge the gap to restore a true copy of the personality? But as magic in Aiers is more of a matter of energy manipulation, that too may be improbable?
Also, in the end, historians would love to hear of true memories of the past, but would a control minded UTI *really* want personalities from the past to deal with? Genetic copies that are programed to be vaguely reminiscent, but also programed to serve, might be the desired outcome?
