It may be vital to learn the history of this city as it relates to Vannozza if we are to find how to cure her of this affliction. Magic often works this way. ( Curses often work this way. They're caused by an event of some kind. )

I could sense it when she showed me. I have a connection to death that allowed me to be aware of its strange grip on her. It is not like someone dying but like a possession. ( It's taking hold of her in a different way, and he does not know why. ) She also holds undead in her family's forest. I thought it might be related, but when I went to see them she'd already removed them from the premises. I sensed some residual presence from them, but the information isn't as much as I had hoped.
