Xanthe is the oldest of Brencis's Boyars. She rules the southeast of Vale Sangora, where she digs up ancient secrets for Brencis's army and raises his Blood Guards.
Xanthe was once a priestess on a Greek island whose name she has forgotten. She is the oldest vampire in Brencis's circle, speaks little, and mutters to voices only she hears.
Her unique gift lets her form whips out of blood to bind her enemies.
Xanthe's Transports, Excavations and Recruiters are events in her lands. Coen can meet her in Svartrau Cathedral during A Monk and a Saint.
Xanthe's blood whips turned the fight against Isbrand, holding two of his limbs.
She springs a trap in Fall Before Dusk. Coen can neutralise her, which earns The Dark Mistress. In the cathedral fight she uses blood whips and a Boiling Blood countdown that can kill Coen.

Brencis is the vampire Knyaz who seized Vale Sangora two years before the story, and the main villain. He is the one who tries and fails to turn Coen, and you have 30 days to beat him to your family.
Crake
Crake leads the Manumits, the rebels fighting Brencis, and his chain is the longest optional storyline in the game. He is also a romance option, but he won't trust Coen until your Infamy is high.
