her ideas could be good, and she won't necessarily make the laws all by herself. she would push for them through MC, and being Queen would allow her to have a bigger influence over the commoners and nobles and use herself as an example to the people for those ideas, as well as having huge lobbying and propaganda potential.
we would need to know her actual ideas before we rule them out completely
and her temper can be an asset for the king, if she directs it towards the right people and not at MC. A strong queen, that does not always need her king to solve issues and resolve disputes, is valuable.
but her drinking though...
Nothing against a strong queen, but that is a thin line to walk, otherwise she is more likely to offend the other party, cause diplomatic issues or make enemys.
I mean, Aelinia's entire thing is basically more power to women and herself of course.
She want's to be like Avila, admired, respected, leading the empire etc, a strong queen for Caudium.
Letting the people believe it's her husband wish makes the decisions, while she does in reality, is what she sees as compromise, as such i would guess her ideas will be in tune with her wish.
I mean, i get that she wants to be more than a trophy wife, but what she wants is so far off past the realm of reality...
It's the 9th century in a realm which is based on the roman empire, not many back then were in fevor for feminism, a roman based society the least of it. In roman society it was completely ok to beat your wife or even kill her for things like damaging the man's honor or property, that was considered private matters.
And if you want implement social reforms, even slowly, you should have a solid rule and stable realm, not a new ruler which is faced with crisis all around, internal & external and a empire near breaking apart, it would be suicidal to even attempt that in the current state of the realm, double so for the east which is pro harem
Now she could have some ideas unrelated to more power for women (or herself), but if so she ain't disclosing it...all i heard from her are her delusions of wanting to be queen and rule.
Even Lydia, which knows way more about her plans and her, is warning you that her ideas are bad, that she's way to overconfident and from what i have seen, i tend to believe Lydia here until proven wrong.
And yeah, no alcoholic with bad temper, which tends to leash out as soon something isn't going her way is a good fit for the queen, she could be the new wine tester thought.
