Nyssa is the human avatar of the dragon Nafia. She appears as a tall, beautiful woman with aristocratic features - chiseled cheekbones, flawless skin, imperious eyes, and a lithe frame. One of her most striking features is her lustrous, silvery-blue hair. Though much older in reality, she looks somewhere in her mid-twenties and carries herself with casual confidence.
She appeared to the Knights of the Dawn, who were at Wyrmroost on a secret mission, offering assistance, but they declined, not wanting to reveal their final destination: the Dragon Temple. Nyssa also helped Gavin by claiming that Navarog had been spotted outside the gates of Wyrmroost.
