The world of Westeros isn’t done with us just yet. Since “Game of Thrones” ended in 2019, HBO has been hard at work expanding George R.R. Martin’s fantasy universe through a growing slate of spinoffs. While “House of the Dragon” has already captured the attention of fans, it’s just one piece of a much larger puzzle.
From animated prequels to epic live-action sagas, here’s everything we know so far about the current—and potential”Game of Thrones” prequels, sequels, and spinoffs in development.
“Game of Thrones” Spinoffs Confirmed and Coming Soon
“House of the Dragon” Season 3
“House of the Dragon” was the first spinoff to make it to air. It dramatizes the “Dance of the Dragons,” which was the brutal Targaryen civil war. The show has been a major success, drawing millions of viewers and is already confirmed for season 3, expected in 2026. HBO has also announced it will conclude with season 4.
“A Knight of the Seven Kingdoms” (2026)
The next confirmed spinoff, “A Knight of the Seven Kingdoms,” adapts Martin’s beloved “Dunk and Egg” novellas. The series follows Ser Duncan the Tall and his young squire, Egg, on their journey to Ashford and beyond.
Production wrapped in late 2024, and HBO teased footage in a Max sizzle reel. Originally slated for a 2025 release, the show has been delayed to 2026. Fans of the books can look forward to a six-episode season that blends humor, heart, and the politics of a Westeros still decades away from the Targaryen civil war.
“Nine Voyages” (Animated)
Formerly a live-action project, “Nine Voyages” has now shifted to animation. The series will follow the legendary sea captain Corlys Velaryon, a central figure in “House of the Dragon,” during his daring journeys to the far corners of Essos. Martin confirmed the project’s format change in early 2024.
In Development (But Not Guaranteed)
“Ten Thousand Ships”
Set 1,000 years before the events of “Game of Thrones,” “Ten Thousand Ships” tells the story of Princess Nymeria and the Rhoynar people’s epic migration. Though previously presumed canceled, Martin revealed in 2024 that a new pilot was being written by playwright Eboni Booth. The project is reportedly back on track, but still early in development.
“Aegon’s Conquest”
HBO is actively exploring a series centered on Aegon the Conqueror and the founding of the Targaryen dynasty. In 2024, “The Batman 2” co-writer Mattson Tomlin was linked to the project, which may include a feature film component. Though details remain sparse, this prequel could offer a fiery return to the roots of Westeros’ most powerful house.
“Game of Thrones” Movie
In late 2024, “The Hollywood Reporter” revealed that Warner Bros. is quietly developing at least one “Game of Thrones” movie. No creative team has been confirmed, and it’s unclear how the film would connect to the existing shows. Still, it’s a strong signal that HBO is serious about bringing Westeros to the big screen.
Canceled, Shelved, or Stalled “Game of Thrones” Spinoffs
“Snow” (Shelved)
Once poised to explore Jon Snow’s life after the series finale, “Snow” was pitched by Kit Harington himself. However, as of early 2024, Harington confirmed the project has been shelved, citing a lack of creative spark.
“Bloodmoon” and “Flea Bottom” (Canceled)
Before “House of the Dragon,” HBO developed a costly pilot for “Bloodmoon,” a prequel starring Naomi Watts. Despite the $30 million investment, it was ultimately scrapped. “Flea Bottom,” set in the slums of King’s Landing, was another early concept that never made it past the idea stage.
“Empire of Ash” (Canceled)
Intended to explore the mysterious fall of Valyria, this rumored project (possibly titled “Empire of Ash”) never materialized. Writer Max Borenstein was reportedly involved, but there’s been no recent development.
“The Golden Empire” (TBD)
An animated series set in Yi Ti — an Eastern empire inspired by Imperial China — “The Golden Empire” remains unconfirmed beyond mentions on Martin’s blog. It’s part of the four animated shows he referenced in 2024.
While only a handful of “Game of Thrones” spinoffs are moving forward, HBO clearly isn’t closing the book on Westeros anytime soon. Whether on HBO Max or the big screen, fans can expect more swords, dragons, and dynastic drama in the years to come.
