Cleo is a blue drake, and is the familiar of Arionrhod Graylock Zvedzy. Obnoxious, opinionated, and overweight, Cleo has not adventured with Arionrhod for many years, and is instead left largely at the keep in Mordentshire where she annoys Niko, smokes foul-smelling cigars, and generally delights in doing whatever she desires.
