– Torisen's narration, Dark of the Moon, "Chapter 10: The Lurking Past"
Lady Kallystine is Caldane's favorite daughter.
She is Rawneth's great-niece and possesses a knack for and an obsession with sorcery and "science." This leads to her attempt to create a liquid that could transfer the youth of one person to another.
Kallystine knows for wearing risqué, lingerie-like masks.
The Matriarchs kept Kallystine at the lowest level of the Women's World, for none of them trusted her.
On Adric's advice, Torisen took Kallystine as his limited-term consort after he became Highlord, to get Caldane's support. Their contract did not include children, but the Caineron were sure Kallystine would seduce him, and he would extend the contract when it came up for review. While she did seduce him, he also came to hate her. By the time of the books, Torisen is avoiding her, and waiting for the contract to expire. He cast her off after she attacked him in Seeker's Mask.
After the events of Seeker's Mask, Kallystine came to hate her sister Lyra, to the point where Lyra was sent away from Restormir to the Women's Halls at Gothregor for her own protection.
↑Seeker's Mask, "Part I", IV — "she wore no mask but a delicate lace-work of leaf gold, dusted as lightly on her face as the iridescence on a jewel-jaw's wing."
↑Seeker's Mask, "Part II: Gothregor", V — "Instead of her usual daring mask, Kallystine wore"
↑Seeker's Mask, "Part I", IV — "kept as she was at its lowest level—more of Adiraina's work, surely, as though she couldn't be trusted with their stupid little secrets!"
↑Seeker's Mask, "Part I", VI — "Odder still that they [the matriarchs] would tell Kallystine, whom no one trusted."
↑Dark of the Moon, "Chapter 6: The High Council" — " 'On your advice, I took Caineron's daughter as a limited term consort, and that did keep her father off my back for nearly a year.' "
↑Dark of the Moon, "Chapter 6: The High Council" — " 'Kallystine was sure I would extend the contract to include children.' "
↑To Ride a Rathorn, "Chapter XIX: Darkness at Noon", III — "His former consort had been adept at intoxicating the senses, but with an after-taste that had made him both loathe and mistrust his own passion. One of the Highborn subsequently thrown at him, a ridiculously young Ardeth girl, had seen enough to suggest that Kallystine had used potions to entrap him."
↑Seeker's Mask, "Part I", II — " 'When the Highlord stopped here last fall on his way to the Cataracts, he didn't so much as send her word, much less visit her. And he's had no trouble staying away all this past winter.' "
↑To Ride a Rathorn, "Chapter XIX: Darkness at Noon", I — " 'Nearly everything is, in the Women's Halls. I'd ask to go home, but Kallystine would probably kill me.' "
