The High Septon’s recent admonishment of Rhaenyra in House of the Dragon may be more than just a religious rebuke; it appears to foreshadow the emergence of one of the queen's most dangerous future adversaries. The warning, delivered in the third episode of the season, seems to allude to the Shepherd, a pivotal character from George R.R. Martin's Targaryen history book, Fire & Blood, who has yet to be introduced in the series.
During a conversation with Rhaenyra, the High Septon cautioned her against making an enemy of the Faith, stating, "It exhorts and comforts and binds together your people. Underestimate it at your peril." He further condemned dragons as "a profane magic created in darkness and pride and lust for power, for impunity. They destroy, but they do no create." These words resonate with the character of the Shepherd, who emerges later in the historical account of the Dance of the Dragons.
In Fire & Blood, the Shepherd is depicted as a beggar-like, one-handed old man whose true identity is unknown. He gains a significant following among the common folk who have endured immense suffering during the war. Preaching in the devastated Seven Kingdoms, he rails against Queen Rhaenyra and proclaims the end times, framing dragons as demonic entities. This message, amplified by the widespread terror and destruction wrought by dragonfire, finds fertile ground among the frightened and enraged populace, echoing the High Septon's condemnation of the creatures.
Showrunner Ryan Condal has remained deliberately vague about whether the Shepherd will appear in the current season or the confirmed fourth and final season. However, he acknowledged the significance of this narrative thread and its thematic relevance. Condal explained that the Targaryens' relationship with dragons often alienates them from the common people, making them appear both alluring and unholy to those with strong religious convictions. He noted the contrast between the Hightowers' connection to the Starry Sept, the religious center of Westeros, and the Targaryens' more distant relationship with the Faith. This divergence, Condal suggested, highlights a growing divide, framing the Targaryens as "others" in the eyes of a populace that clings to established faith.
Condal further elaborated on how this religious division plays into the perception of Targaryen legitimacy, contrasting Rhaenyra's lineage with that of Aegon II. While Aegon, despite having a dragon, is seen as more relatable due to his gender and Westerosi heritage, Rhaenyra's side, particularly Daemon, is viewed as inherently alien. This "othering" extends to their religious practices, with the Targaryens maintaining a tenuous, pragmatic relationship with the Faith, prioritizing their own gods and the power of their dragons over traditional religious dogma.
