Cerro

From Witcher Wiki

Queen of Redania, wife of King Vridank. Adopted Lara Dorren's daughter and named her Riannon. Was probably killed by Falka.

[edit] The Witcher computer game

Zoltan Chivay can mention her and her husband over the course of a rather philosophical conversation with Geralt: Nicely put, but as young Cerro said to King Vridank on their first date: "Does it have any practical uses?"
