Seamus Pegg is one of Genshin Impact's most frequently mentioned yet least-seen characters. The father of Jean and Barbara, and the highest-ranking clergyman in Mondstadt, he spent years existing only in character stories, in-game dialogue, and the pre-release manga. With the Version Luna VI update, players can finally see him in person — though not as a playable character.
Quick answer: Seamus Pegg is Jean and Barbara's father, the Cardinal (formerly titled Seneschal) of the Church of Favonius, and one of Mondstadt's key leaders. He originally hails from Nod-Krai and was a famous adventurer before settling down. He appears as an NPC in the Luna VI patch.
Seamus Pegg's Role in Mondstadt
Seamus holds the title of Cardinal of Daybreak and serves as the Seneschal of the Church of Favonius, making him one of the most powerful figures in Mondstadt's governance. He oversees the Church in its entirety, including stewardship of the Holy Lyre der Himmel — the sacred instrument that plays a role early in the game's main story when the Traveler and Venti try (and fail) to borrow it, partly because Seamus's signed authorization is needed and he's already left on Varka's expedition.
His position is roughly equivalent to a chief administrator for Mondstadt's religious institution, and he handles the bulk of the organizational work that Grand Master Varka famously avoids. Jean inherited this workaholic tendency from her father, a detail noted by the NPC Anselm in-game.
Family and Personal History
Seamus married Frederica Gunnhildr, a renowned knight of the Gunnhildr clan, and the two had two daughters: Jean and Barbara. The marriage eventually fell apart, and the couple separated. Frederica took custody of Jean, while Barbara stayed with Seamus. This split created a lasting awkwardness between the two sisters that surfaces throughout their character stories and interactions.
Despite the divorce, Seamus kept Frederica's old outfit — a set of clothes she wore as the Alder Knight, known in-game as Gunnhildr's Legacy (Jean's alternate costume). The fact that he held onto it suggests the relationship, while over, still carries weight for him.

From Nod-Krai Adventurer to Mondstadt Leader
Seamus originally hails from Nod-Krai, the northern region that became central to Genshin Impact's recent story arcs. He left his homeland because he had "no one left to miss" there, and he spent years traveling Teyvat as a well-known adventurer. During those travels, he encountered a young Varka wandering foreign lands, searching for a reason to become a knight.
After listening to Varka talk about his homeland and the people he cared about — particularly Frederica Gunnhildr — Seamus helped him realize that protecting those people was reason enough. To give Varka an excuse to return home without feeling embarrassed by the simplicity of that revelation, Seamus offered to accompany him under the pretense of needing an escort. He later admitted he was specifically curious about Frederica. Once in Mondstadt, Seamus joined the Church of Favonius and eventually rose to its highest position.
The Manga and the Fatui Incident
Seamus's earliest visual appearance came in the official Genshin Impact manga, which was released before the game launched. In Chapter 1, he attends Ludi Harpastum festivities at Diluc's manor. When the Fatui diplomat Dottore and his subordinate Krupp demand an audience, Seamus agrees to a private meeting alongside Diluc and Kaeya to discuss the Fatui's desire to recruit Mondstadt citizens.
Seamus was unwilling to capitulate but couldn't find leverage to push back against the Fatui's diplomatic pressure. The situation resolved itself only because Dottore became distracted by something more interesting — Diluc's Delusion — and pulled his diplomats out. Seamus got drunk celebrating the news and excitedly told Kaeya. The entire incident left Mondstadt at a diplomatic disadvantage with the Fatui for years afterward, something Seamus deeply regretted.
This period also overlapped with Eroch's conspiracy with Dottore, which led to the awakening of Ursa the Drake, the death of Diluc's father Crepus, and Diluc's subsequent resignation from the Knights of Favonius.
Varka's Expedition and the Return to Mondstadt
When Varka organized his expedition to confront an Abyssal calamity threatening northern Teyvat, Seamus joined him. His Church duties were handed off to Cardinal Calvin during his absence. Within the expeditionary force, Seamus continued doing what he does best: handling all the administrative work that Varka refused to touch.
The threat turned out to be the Wild Hunt crisis in Nod-Krai. After Rerir's defeat during the Archon Quest Song of the Welkin Moon: Act IV, the immediate danger subsided, and Seamus departed the expedition for what NPCs describe as "private matters." Dialogue between the NPCs Helmut and Arved suggests these private matters may relate to Frederica, who had returned to defend Dornman Port around the same time.
Rosaria's birthday letter mentioned the Church of Favonius clergy cleaning in preparation for Seamus's return. By Jean's birthday, he had already arrived home — Jean's birthday mail describes Seamus and Barbara surprising her with a homemade dinner. Seamus personally made pizza.
Luna VI In-Game Appearance
Seamus Pegg's in-game model was revealed during the Luna VI livestream and subsequently appeared in the Version Luna VI "Augured Homecoming" trailer. His design closely matches his manga look: long blond hair, glasses, and a crimson-and-white cloak befitting his clerical rank. The model is distinctly NPC-quality, lacking the visual details that distinguish playable characters — no Vision, no combat-ready design flourishes.
He is expected to appear during Luna VI's main quest content, which introduces the Dornman Port area in Mondstadt, and will also feature in the version's Character Anecdotes.
Name Changes Over the Years
Long-time players may remember him by a different name. In the manga, he was simply called "Seamus." During the Closed Beta Test, Jean and Barbara's character stories referred to him as "Seamus Pegg." When Version 1.0 launched, his name was changed to "Simon Page" — but Version 1.4 reverted it back to Seamus Pegg, which has remained his official English name ever since.
The name Séamus is the Irish form of James, and both James and Simon (his temporary rename) happen to be names of two of Jesus's Twelve Apostles — a fitting coincidence for the head of a church. His name is properly pronounced "SHAY-mus," following Irish Gaelic conventions, not "SEE-mus."
Seamus Pegg spent over five years as one of Genshin Impact's most prominent offscreen characters, shaping Mondstadt's politics and family dynamics without ever showing his face in-game. His NPC debut in Luna VI finally puts a model to the name, even if players won't be adding him to their party rosters. For fans invested in Mondstadt's lore — and especially in Jean and Barbara's complicated family — his arrival fills in a piece of the story that's been missing since day one.
