Further info: I gave her the barony because she's got wicked stewardship and the Horny dynasty is pretty big (currently 734 members. Inviting all the houseless people in always making courtiers and family marry courtiers in other courts so I can steal those courtiers doing the marriages for traits reforming the religion for gender equality polygamy and sacred child birth). I figured she'd turn that barony into an absolute powerhouse but she died almost immediately. The cause of death is listed as mysterious circumstances. Did the game kill her for some stupid reason? Was she suddenly exposed to a murder scheme when no longer under the protection of my spymaster? She was low-key my favourite kid because she was the one that made my current character into a witch and her stewardship had helped boost my income as my steward, so I'm kinda bummed by her getting yeeted.
