Guys any spoilers ?? Whether the Duke and duchess have their own children?? I don't like i...

I don't have actual spoilers, but I have suspicions. She'll probably get adopted by the duke and duchess at some point since we all know there is no way in hell the duke is going to kill her on her 18th birthday and they treat her like their daughter already. I also suspect, to deal with the whole execution at 18 thing, the duke will take over the throne from his brother (who I kinda suspect was behind the deaths of the previous emperor and Noah's mom's somehow, so that would make taking the throne justified) and then they give the FL the title for Sheridan Dukedom since she's a golem master and therefore can make the mansion move like a mobile fortress. I also suspect (and hope lol) that FL ends up with Noah.

That would be great.

As for the duchess?? What about her??
So the Duke will become the emperor right?
Yeah about then not killing the FL it is true , they won't kill her..
But will the Duke couple have their own children?

I don't think he's gonna take over the throne, I have a feeling they're gonna use the fact that she is a golem mage(she talks to rocks) so she won't be executed and will be adopted by the duke and duchess.

I mean if the duke becomes emperor, then the duchess will become the empress, at least if we're talking about a happy ending. I can't imagine them separating, even temporarily, after the most recent chapter. If the duke and duchess do have kids (and they probably will at the end or in an epilogue or something) then their kids would be next in line for the throne AND the Sheridan Dukedom. If she's adopted she'd just be the older sister of the duke and duchess' future kids. So, the FL isn't "stealing" anything even if she does get the Sheridan title lol.

My thought process on saying that the duke and duchess would take over the throne is that the duke's brother is a typical asshole royal type of character. I mean he started spouting the same shit as the FL's now dead brother about her having a tainted bloodline, so he's clearly not meant to be a good guy here lol.

The brother already made the duke swear that he would execute FL on her 18th birthday, and I don't think her being a golem master would make him change his mind (considering he declared it publicly and wouldn't want the royal family to lose face or whatever, and already thinks of her as a lowly tainted bloodline with the possibility of destabilizing their recently conquered territory on account of her having royal blood). Frankly, her being a golem master would make her more of a threat in his mind since she could use her powers to try to regain control of her birth country. He likely wouldn't think, "Oh good, the prisoner that we're supposed to execute when she turns 18 is a super powerful and rare mage. Let's just NOT kill her then!" I mean, if he was smart and understood people, he would be able to understand that she didn't feel any attachment to her birth country due to how she was treated to start with and also never sought power, and therefore wouldn't have any desire to take back control over her birth country or overthrow him. He also might be able to understand that he could make her loyal to his country by treating her well and be able to make use of her super strong rare abilities. But, he's been depicted as self-centered and egotistical so far, so I doubt he understands people well enough to understand that. He also doesn't seem smart enough to understand it based on psychological analysis or something, so he'll probably just order her to be executed (or covertly assassinated) immediately if he finds out she's a golem master.

So, they'll have to deal with him somehow to stop the FL's execution (being adopted by the duke would also probably not be good enough for the brother to feel assured that she won't cause problems for him by existing either). The reason I think dealing with him will involve the duke taking over the throne is that I don't remember any mention of other members of the royal family other than him and his brother, and I'm also fairly sure that the death of Noah's mom (the previous golem master and master of the mage tower) and the previous emperor (either the duke and his brother's dad or their brother, don't remember if that was specified) was plotted by the duke's brother (idk how yet) so that he could be the emperor and get rid of a threat to his power when on the throne (the mage tower master). So the brother is probably going to get overthrown for his crimes, the question is who will take over after him. I'm saying the duke because, again, I don't remember any other members of the family being mentioned and no other characters that could take over that position have been introduced either (I also highly doubt they'll suddenly jump to democracy or something).

I also just had the thought that maybe the previous emperor and Noah's mom are being kept alive under the rubble of the collapsed golem somehow by golem magic, so then when Noah discovers this during his research he would probably somehow convince the duke to bring FL to the rubble (if it's not already revealed that she's a golem master by that point) and then she could wake up the golem and then the previous emperor and Noah's mother are free. In that case the previous emperor would just get his throne back and the duke probably wouldn't take over the throne.

what if they're gonna add a plot where mc can switch bodies or severe blood ties in ancient magic like they somehow find out that some ancient magic (bonus points if it was the first original golem Master's loved one or something) or there's a law that can void her getting execution unless certain requirements are met or maybe make a binding oath to the duke or "royal family" that can make her execution voided

So basically she can't die from execution? I mean that would be cool, but also out of nowhere lol. And if she switched bodies to avoid death, that would mean she was stealing someone else's body. I doubt she would do that and there's no basis for any power like that to exist in this story so far. The binding oath would be cool and somewhat plausible though. Like maybe the first golem master made a pact with the royal family saying that you couldn't execute a golem master. That I could see happening.

Or maybe another plot twist about the ML's birth mother disappearing without a trace after she was born. A secret identity for example? Lol at this point anything is possible. For a fact that she is a golem master must be from her ancestors.

ML main lead not ml as in male lead

That's true lol. For all we know, she might not even be the daughter of the royal family that got killed. Maybe her "father" just kept her because he knew about the golem master lineage, but just told the queen that she was an illegitimate child. In that case, there's not even a reason for the execution anymore lol.
