Game of Thrones Spin-offs Ranked: House of the Dragon Prequels
Game of Thrones spin-offs have been the hot topic among fantasy fans since the original series concluded its polarizing final season. The immense success and rich lore of Westeros left an open invitation for further exploration, and HBO is certainly taking advantage of that opportunity. While rumor and speculation have swirled around countless potential projects exploring Aegon’s Conquest, the story of Jon Snow, and even the Age of Heroes, the current focus has firmly landed on the Targaryen millennia. Currently, the most prominent and realized project is House of the Dragon, but understanding its place requires looking at the landscape of planned and scrapped prequel ideas.
The world George R.R. Martin created is vast, making the potential for prequels almost limitless. However, translating that potential into compelling, high-quality television requires careful selection and massive resources. Here is a look at the current state of the Game of Thrones prequel universe, ranking them based on development status, perceived potential, and how closely they align with the source material audiences are eager to revisit.
The Reigning Champion: House of the Dragon (Season 2 Confirmed)
House of the Dragon sits squarely at the top because it’s the only fully realized, critically acclaimed prequel currently airing. Set nearly 200 years before the events of Ned Stark’s arrival in King’s Landing, the series focuses on the brutal civil war known as the Dance of the Dragons—the catastrophic conflict that pitted half the Targaryen family against the other over the succession crisis following King Viserys I.
Why It Ranks #1:
- Established Success: It proved that audiences were willing to return to Westeros when the storytelling quality was high. Its focus on political maneuvering, dragon-riding elites, and high stakes resonated deeply.
- Rich Source Material: It draws directly from George R.R. Martin’s historical novel Fire & Blood, providing a detailed, messy, and emotionally potent blueprint for the narrative.
- Familiar Ground (With a Twist): It retains the grandeur, incestuous drama, and fiery spectacles fans crave, but shifts the focus entirely to the dragon-riding dynasty, distinguishing itself from Kit Harington’s adventures south of the Wall.
The success of House of the Dragon has cemented HBO’s faith in the Targaryen saga, making it the cornerstone of the entire expansion effort.
The Lost Legend: Robert’s Rebellion (Scrapped)
While not officially in development right now, “Robert’s Rebellion” remains the most frequently discussed and anticipated prequel among longtime novel readers. This era, occurring roughly 300 years before Game of Thrones, covers the events leading up to and resulting in the overthrow of the last Targaryen king, Aerys II (the Mad King), by a coalition led by Robert Baratheon, Ned Stark, and Jon Arryn.
This imagined series would have been essential viewing for fans wanting to understand the context that shaped the original GoT timeline. We would have seen a young, charismatic Robert Baratheon, the complex relationship between Rhaegar Targaryen and Lyanna Stark, and the final, devastating moments of Targaryen rule.
Why It’s Ranked High Despite Being Scrapped: The scope of this story is immense, essentially functioning as a foundational myth for the entire previous series. Had it been prioritized, it would have offered a more direct, character-driven narrative connecting the two major series. Currently, elements that would have been covered in this period are being teased or partially explored in House of the Dragon, although the Dance of the Dragons precedes Robert’s Rebellion by nearly 150 years.
The Northern Frontier: Snow (In Development)
The only other confirmed, actively developing project is the series tentatively titled Snow, centered on Jon Snow following the conclusion of Game of Thrones. This appears to be a direct sequel rather than a prequel. Jon Snow, banished to the Night’s Watch and forced to live beyond the Wall following his assassination of Daenerys Targaryen, would presumably explore what lies in the true unexplored North.
This project is reportedly a “sequel series” spearheaded by Kit Harington himself, who is actively involved in its concept development.
The Unique Challenge of the Snow Sequel:
The key question surrounding this endeavor is how to maintain high stakes in a world where the ultimate, existential threat—the White Walkers—has already been defeated. If it focuses purely on exploration and the remnants of wildling culture, it might lack the political tension that drove the main series and House of the Dragon. Its ranking is relatively low because it is the most vulnerable project; sequels to massive stories often struggle to recapture the magic without repeating plot devices.
The Age of Exploration: Tales of Dunk and Egg (Development Stalled)
Based on George R.R. Martin’s novellas, Tales of Dunk and Egg (often referred to simply as Dunk and Egg) is set about 90 years before Fire & Blood. The central figures are Ser Duncan the Tall (a giant knight) and his young squire, Aegon V Targaryen (Egg), who travel the Seven Kingdoms seeking adventure and justice.
This would have been a stark departure from the massive, sprawling epics of the other series. It is smaller in scope, focusing on episodic adventures, chivalry, and early encounters with the common folk, offering a much brighter, less doom-laden look at Westeros.
Why It’s Not Higher: While beloved by book readers for its charm and character work, it involves relatively unknown characters compared to the Targaryens or Starks. Reports suggest this project has been challenging to adapt, with HBO reportedly seeking a version closer to the scope of the main series or House of the Dragon, which risks losing the quiet appeal of the original novellas.
The Distant Past: The Long Night (Concluded Development)
This ambitious project was set thousands of years before Game of Thrones, during the Age of Heroes, focusing on the original war against the White Walkers. It was planned to be a vastly different show in tone and setting, potentially using different visual styles and lacking the familiar castles and noble houses viewers know.
Why It’s Lowest Ranked: This series was ultimately scrapped by HBO after shooting a pilot episode. While the premise was fascinating—showing the founding myths of Westeros—it was apparently too removed from the core sensibilities and aesthetics that made the parent show a hit, making it the most distant relative in the current family tree.
In conclusion, the future of Westeros content is currently defined by the fire and blood of the Targaryens. While the legacy of Robert’s Rebellion and the future of Jon Snow loom large, House of the Dragon has successfully proven that when adapting source material with focus and quality, the reign of dragons is far from over.
