For a series filled with dragons, brutal battles, and shocking betrayals, some of the biggest moments in House of the Dragon are decided far away from the battlefield. Power in Westeros isn’t secured by swords alone—it also depends on symbols, traditions, and the institutions that determine whether a ruler is truly accepted.

That’s exactly why HBO’s latest promotional material for House of the Dragon Season 3 has sparked fresh discussion among fans. The network has officially confirmed the return of a character who hasn’t appeared since Season 1, bringing back an important figure whose influence could prove just as significant as any dragon rider.

The returning character is the High Septon, portrayed by Simon Chandler, and his reappearance comes at a pivotal point in the Dance of the Dragons. With Rhaenyra Targaryen now sitting in King’s Landing, the timing of this reunion raises major questions about legitimacy, faith, and the political future of the Seven Kingdoms.

House of the Dragon Season 3 Officially Confirms High Septon’s Return After Long Absence

HBO has released promotional photos confirming that Simon Chandler’s High Septon will return in House of the Dragon Season 3 Episode 3, reportedly titled something like “Queen’s Landing” or described as a conceptual Rhaenyra-focused episode.

The official images show the High Septon meeting with Rhaenyra Targaryen (Emma D’Arcy) after she has claimed King’s Landing, marking the character’s first appearance since Season 1.

Although he is commonly known as the High Septon, the character has also been referred to or credited in some contexts as Septon Eustace or High Septon Balman, reflecting slight variations across the show’s adaptation.

His return may initially appear minor compared to the show’s larger conflicts, but within the political landscape of Westeros, it could become one of Season 3’s most meaningful developments.

Why Fans Haven’t Seen the High Septon Since Season 1

Simon Chandler’s character last appeared during one of the most significant political moments in the series.

In Season 1, Episode 9 (“The Green Council”), he officiates Aegon II Targaryen’s coronation at the Dragonpit.

During the ceremony, he anoints Aegon with sacred oils, offers prayers to the Seven, and formally proclaims the new ruler with the declaration:

“All hail His Grace, Aegon, Second of His Name, King of the Andals and the Rhoynar and the First Men, Lord of the Seven Kingdoms, and Protector of the Realm.”

After that pivotal coronation, the character disappeared from the story—until now.

Why the High Septon’s Meeting With Rhaenyra Could Be One of Season 3’s Biggest Political Moments

The promotional images reveal the High Septon meeting directly with Rhaenyra Targaryen after she has secured King’s Landing.

As Rhaenyra begins consolidating power following major events including the Battle of the Gullet and the Fall of King’s Landing, she faces a challenge that extends beyond military victories.

She must also deal with Westeros’ most powerful institutions—including the Faith of the Seven.

Because Rhaenyra’s original crowning at Dragonstone happened under extraordinary circumstances, many observers believe a formal coronation or religious blessing could become increasingly important as she attempts to strengthen her legitimacy.

Whether that ultimately happens remains to be seen, but the High Septon’s presence immediately raises the political stakes surrounding her rule.

Who Is the High Septon in House of the Dragon?

Within the world of Westeros, the High Septon serves as the supreme leader of the Faith of the Seven, the dominant religion across much of the realm.

His responsibilities include:

• Presiding over royal coronations.
• Performing blessings.
• Overseeing major religious ceremonies.
• Representing one of the kingdom’s most influential institutions.

In the television series, he is based in King’s Landing, while maintaining ties to Oldtown, the traditional seat of the Faith.

Interestingly, subtitles and production credits have varied over time, referring to him as High Septon, Septon Eustace, or High Septon Balman, highlighting the show’s evolving adaptation choices.

Why the Faith of the Seven Matters During the Dance of the Dragons

The civil war between the Greens and the Blacks is fought with armies and dragons, but public legitimacy remains equally important.

The Faith’s support—or its refusal to offer support—can dramatically affect how the people of Westeros perceive a ruler.

That makes the High Septon’s return especially significant.

As Rhaenyra attempts to establish authority over King’s Landing, securing recognition from one of Westeros’ oldest institutions could become politically invaluable.

The storyline also reinforces one of House of the Dragon’s recurring themes: that crowns alone do not guarantee power.

How Fire & Blood Handles This Story Differently

George R.R. Martin’s Fire & Blood presents the Dance of the Dragons as a historical chronicle compiled from multiple in-universe sources, each carrying its own biases.

The television adaptation streamlines several of these historical figures.

In the books:

• The unnamed High Septon during this era is elderly and frail.
• He remains in Oldtown.
• He does not travel to King’s Landing for Aegon II’s coronation.
• Instead, Septon Eustace, a royal septon and strongly pro-Green chronicler, performs the ceremony.

Septon Eustace later becomes one of the two primary historical narrators documenting the Dance.

The other is Mushroom, whose writings often favor the Black faction.

Eustace’s accounts are notably biased toward Aegon II and the Greens, contributing significantly to the negative historical portrayal of Rhaenyra, including accounts emphasizing scandals and instability.

Why HBO Appears to Have Combined Multiple Book Characters

Rather than introducing multiple religious figures with overlapping responsibilities, House of the Dragon appears to simplify the narrative.

Simon Chandler’s character effectively incorporates elements associated with Septon Eustace while simultaneously holding the title of High Septon.

This kind of streamlining is common in television adaptations, helping audiences follow complex political stories without introducing an overwhelming number of characters.

At the same time, the decision potentially gives Simon Chandler’s character an even larger role than either individual counterpart held in the source material.

What the High Septon’s Return Could Mean for Rhaenyra’s Story

Although Episode 3’s full events remain under wraps, the High Septon’s return naturally opens the door to several major themes.

His involvement could explore:

• Legitimacy.
• Religious authority.
• Political propaganda.
• Rhaenyra’s ongoing struggle to rule as a woman within a deeply patriarchal society shaped by faith and long-standing tradition.

These issues have always been central to the Dance of the Dragons, making the High Septon’s reappearance feel particularly timely as Rhaenyra transitions from claimant to ruler.

House of the Dragon Season 3 Context: Why This Return Comes at the Perfect Time

As of early July 2026, House of the Dragon Season 3 premiered around June 21, 2026.

By Episode 2, Rhaenyra has taken King’s Landing, setting the stage for Episode 3 to examine the realities of governing rather than conquering.

Season 3 also continues introducing major new developments across Westeros, including:

• Ormund Hightower.
• Daeron Targaryen.
• The continuing conflict between the Greens and the Blacks.
• Large-scale battles that reshape the war.

Within that broader story, the High Septon’s meeting with Rhaenyra represents another layer of political complexity, highlighting the challenges of stabilizing the capital while managing lingering Green loyalists and maintaining relationships with powerful institutions.

Although no major spoilers beyond officially released promotional material have emerged, his return emphasizes the lasting influence of the Faith of the Seven—a dynamic that longtime Game of Thrones viewers may recognize from the later rise of the High Sparrow.

A Small Return That Could Have Massive Consequences

At first glance, the return of a character absent since Season 1 might not seem like one of House of the Dragon Season 3’s biggest developments.

However, the High Septon occupies a unique position within Westeros. He represents faith, legitimacy, and the moral authority that every monarch ultimately seeks.

With Rhaenyra now ruling from King’s Landing, dragons may have won her the city—but winning the kingdom is an entirely different challenge.

As Season 3 continues unfolding, Simon Chandler’s return could prove that in the world of House of the Dragon, the most influential players aren’t always the ones riding dragons.
