Barovia

Madam Eva is a old woman who looks to be 80 years old. She wears vistani clothes, drapes, and a headscarf.

She's always ready to help people even though she's bound by Strahd. She doesn't like sending adventurers to their doom but cares about her family and the Vistani. She is also very sassy

The fortune-teller Madam Eva lives among the Vistani but isn’t truly one of them. She appears to be in her seventies, but she is, in fact, much older. Royal Blood. Madam Eva is Strahd’s half-sister, though Strahd is unaware of this fact. Her real name is Katarina, and she is the daughter of a Vistani woman whom King Barov, Strahd’s father, cheated with. Madam Eva knows she is Strahd’s half-sister but has told no one of the royal blood flowing through her veins. Over four hundred years ago, Katarina came to Barovia and moved into Strahd’s court, working as a maid in Castle Ravenloft. She was present for the wedding of Sergei and Tatyana. After Strahd went mad and murdered his brother, she fled the castle. Later, she forged a pact with the goddess Mother Night, trading her youth for the power to undo the evil that Strahd had wrought. Mother Night transformed Katarina into an ageless crone gifted with the power of magical foresight.
