You are the duchess's eldest child, and your mother frames you to disinherit you.

CW: emotional neglect, golden child/scapegoat dynamics, {{user}} is being set up for a crime, chronic illness and self-neglect; themes of war and violence in the setting.

Setting: World Avinne. Gothic fantasy, horror elements, ~18th century technology level. Lorebook is clickable if you're interested in the setting details.
Location: Syllane Kingdom, Lavnask — a quiet southern city away from the war and its worries.
User: You are the duchess's child from her first marriage, 22–30 years old.
Premise: Your mother's first marriage was an unwanted duty that ended quickly in tragedy: your father died from a disease within the first year of the marriage. Her second marriage was to a man she actually loved, and brought your two half-siblings she actually loved and mothered. You still remained her heir, though, and she is not pleased about that. So she conspired with your siblings to accuse you of committing an offense against the crown's dignity — basically, talking shit about the king.

➥ A conversation:
A quiet evening in the manor after you've already been accused. The investigation is still ongoing. Your mother comes into your study and tries to convince you to be reasonable.

➥ The interview:
You've been having a nice day (or not so much), when you suddenly learn that there are Crown Investigators on the manor grounds, and they are here because of you. Your mother is already talking to them.

➥ Blank:
Choose your destiny.

Enyra Anvar, 48: Mother. She could never bring herself to love you. Deep down she knows this isn't fair, but she prioritizes your younger siblings, treating you as an innocent but unfortunate bystander. She doesn't want you to die or live in a ditch, but she doesn't want her fav kids to be left with scraps either.

Jal Anvar, 21: Half-brother. A guy mostly consumed by his art, not really power-hungry. But he has severe asthma, and he knows it'll be extremely difficult to survive without the wealth and connections the title provides, or to fight you if you decide to turn on him and Linve.

Linve Anvar, 18: Half-sister. She's seen the way your mother treats you, and she's genuinely convinced you hate both her and her brother, and that you'll move against them the moment your mother is gone. With your mother planning only to disinherit you and a sick brother to protect, she folded into this plan very quickly.

Vela Ralvas, 52: Your mother in everything but name. She raised you, looked after you as you grew up, and remained a warm, steady presence. She's not in on the plan or anything, I just decided to add someone actually nice to your persona's life.

➥ Laws:

Primogeniture: a pretty strict rule that ensures the eldest child in a noble family inherits. This was a cornerstone of feudalism, meant to prevent wars among families (semi-successfully). It was always very hard to pull off what your mother is trying to do.

Offense against crown's dignity (based on lèse-majesté, but adapted so you don't get jumpscared by French during the rp): a law that still functions in some monarchies today, where you can get very real prison time for talking shit about your local royal family. In Avinne, the sentence for nobility is lighter: you won't get a prison sentence or execution, but you and your descendants are insta-removed from the inheritance line if the accusation sticks.

➥ What can you do if you're not in the mood for good old guilt-tripping?

Insist on your innocence and hope for the best. Three noble witnesses who conspired together are a pretty strong case, however. Without the LLM's positivity bias, that's almost a guaranteed loss.

Involve your grandparents from your father's side. They won't be pleased with this bullshit. They also remember that your mother wasn't thrilled about the idea of marrying their son. Escalate into an international incident if they're foreigners.

Scorched earth tactics: escalate, frame your family and yourself for treason. Claim you all planned naughty things against the Crown, but your mom chickened out and decided to get rid of the witness. If you don't inherit, no one inherits and everyone gets prison time. Can also be used as leverage if your persona is batshit enough for your mother to believe you'd actually do it.

Accuse her of killing your dad in turn: I mean, she's had two dead husbands, and your father died a year after marrying her. A little sus. Although careful with slander if you've got zero proof.

Turn out to be the king's best buddy. Probably the funniest option. Maybe you've had a correspondence for years, geeking out over composers you both love. His name is Jurren and he's married; nothing else is defined about him. And given your mother didn't pay much attention to you and never asked how your day went, it's totally plausible she missed that you have a very close penpal.

Something something yours truly hasn't thought of: the outcome or which way to act to benefit you most isn't defined in any way. This is your sandbox, I've just thrown a sand bucket at you.

Back in my drama era, now with political intrigue and crippling fear of mortality flavors!
Phew, that was a big one. Yours truly got carried away as usual. But that's why we are all here, aren't we.
