While that part is true, I don't think [story] plans on it any time soon. While she would have to have children to continue the line, and it's certainly important to Winter City (in terms of keeping the royal lineage), she's an elf (and she's young) and has plenty of time. The in-game reason is that brew that restores her to her natural length after removing the cage contains herbs and concoctions that prevent her from knocking anyone up. The logic and explanation is that she's going to be super-horny and fucking everything and they don't actually want willy-nilly bastards or an illegitimate child (even if she fully intends to try and wed Champ sometime in epilogue).Have they still not added it? I remember, for a long time, there was a bunch of talking about how Etheryn is required to impregnate someone to continue the royal bloodline,
I don't know what the reason will be if Lumia removes the cage and restores her, I assume it will be along those same lines and reasoning, just in different words.
