Septa Ysabel

Septa Ysabel’s story traces a reversal in religious influence: sent to Dragonstone to challenge the young Queen Alysanne’s marriage, she became one of the queen’s supporters and later helped carry the royal position on that marriage to the wider realm. Her significance lies not in a recorded office or independent political campaign, but in the way her religious authority was drawn into the work of reconciling the crown and the Faith.

Appointment to Alysanne’s Household

After Jaehaerys and Alysanne fled the Red Keep for Dragonstone, the young king and queen had no household of their own beyond the castle’s knights, garrison, and servants. Queen Regent Alyssa arranged for a company of women to attend her daughter, both to provide suitable companions and to influence the royal couple. Ysabel was the senior religious figure among those sent: described as formidable, she was accompanied by two young, wellborn novices, Lyra and Edyth. The aged Septon Oswyck, who had performed the couple’s wedding rites, remained in charge of the sept on Dragonstone.

The women’s assignment had a religious as well as domestic purpose. Alyssa hoped that instruction in the Faith would persuade Alysanne, and perhaps Jaehaerys, that a brother-and-sister marriage violated the Faith’s teaching and ought to be repented. Lord Rogar had a further political interest in the arrangement. He wanted reports on what the king and queen said and did, and was especially determined that their marriage not be consummated. Ysabel arrived as part of a company meant to shape the royal household, but the attempts to change the couple’s course would not have the result Alyssa intended.

A Change of Allegiance on Dragonstone

Prayer, sermons, and readings from The Seven-Pointed Star did not shake Alysanne’s belief that the gods had intended her to marry Jaehaerys and serve as his confidante, partner, and the mother of his children. She also believed he would be a great king and that she would be a great queen. The account describes her as gentle, kind, and loving in other respects, and reports that these qualities affected the women tasked with instructing her. Ysabel, the novices, and the other companions found they could not condemn Alysanne; as time passed, they increasingly took her side.

That reversal matters because Alyssa’s plan had treated religious instruction as a means of separating the young rulers, while Lord Rogar sought to use the new household as a channel for surveillance. Instead, the women became close to the queen whose marriage they had been sent to oppose. The record does not describe Ysabel making a public declaration or confronting either Alyssa or Rogar. It does establish the change in her allegiance through the group’s response to Alysanne and its growing attachment to her.

Service to the King and Queen

Ysabel remained with Jaehaerys and Alysanne after their time on Dragonstone. When the king dismissed Septon Mattheus, who had denounced the marriage, he named the septon and Ysabel among those who would remain at his side. His answer also pointed to a young scholar, Barth, who was coming from Highgarden to attend the royal library. Mattheus disparaged Ysabel because she was a woman, but Jaehaerys’s decision to retain her shows that she continued to have a place in the household despite the prelate’s objection.

Her continued presence linked the private household formed on Dragonstone to the king’s later effort to defend his marriage publicly. That continuity does not make Ysabel the author of the king’s argument: the account credits Jaehaerys, with help from Septon Oswyck and especially Septon Barth, with shaping the case that later became known as the Doctrine of Exceptionalism. Ysabel’s role was among those who carried the king’s message, rather than among the named advisers who devised it.

The Seven Speakers and Exceptionalism

Jaehaerys sent seven religious advocates through the realm to answer opposition to his marriage with persuasion rather than force. The group consisted of three men and four women; Ysabel was one of the women, alongside Queen Elinor, Septa Violante, and Mother Maris. The account specifically says that Alysanne had won Ysabel over while the septa was serving her on Dragonstone. Her selection thus followed directly from the change in outlook that had frustrated Alyssa’s original purpose.

The Speakers praised Alysanne’s piety, generosity, and love for Jaehaerys, and answered objections grounded in scripture and the teachings of earlier High Septons. The doctrine they conveyed affirmed the Faith’s general prohibition on incestuous unions but argued that the Targaryens were an exception: their ancestry and customs came from Valyria, not Andalos, and their possession of dragons marked them as different from other people. Ysabel’s presence among the preachers gave the campaign a religious voice shaped by personal experience within the royal household. The evidence does not preserve her individual speeches or describe her particular route, so her contribution is best understood through her place in the Seven Speakers and the message the group collectively advanced.

Ysabel’s trajectory therefore runs from attempted correction to active advocacy. She was first sent to make the queen reconsider her marriage, but came to support the queen, stayed in the royal household, and joined a kingdom-wide campaign that sought to reconcile the Faith’s doctrines with the Targaryen dynasty’s customs. Through that reversal, a household appointment intended to restrain royal policy became part of the religious network used to defend it.
