CIRI.
Ciri was absolutely ready and willing for this ball. She drank the potion, after all. When she's introduced, it's Princess Cirilla of Cintra, Hen Ichaer, Child of Chaos, Child of Wrath, and the Future Lady of Time and Space. Ciri's look is very Princess who wants to be a gentleman, though there is a white flower in her hair. Her date was Paul Atreides, even though Yennefer made things a little awkward.
