Isolde Winchester

Isolde Winchester (born Isolde Cunningham), official title being Isolde Winchester, the Queen of Fantasica and the Mistress of Jewels, Queen Ruler of Woesien, is a supporting character featured in Kings and Queens, and is considered the secondary antagonist of the book. She is the firstborn daughter and child of Lord Atticus and Lady Gwyneth Cunningham, and the elder sister to Ser Dean and Lord Wilbert. She is the Queen Wife to King Maurice and the mother of his three children; Wesley, Jewel and Lance. During the events of Kings and Queens, she is the center of most problems and issues that occur in the main plotline in Woesien. She coordinates the murder of her sister-by-law's younger sister, Anabel Messer, alongside intentionally murdering the unborn child of Lady Tilly Winchester, unbeknownst to the latter. She also poisons her own husband with the help from Castor Foxx, the Grand Magister of Jewel Keep.

Isolde is the last supporting character to be featured in the novella, as Lady Tilly has the final viewpoint chapter, before the Epilogue.
