Five Possibilities for a Game of Thrones Spinoff

Game of Thrones might be fast approaching its final episodes, but HBO has continued to tease fans about a possible prequel series. After all, Westeros has a long and blood history, filled with countless wars, assassinations, and shocking betrayals. Because of George R.R. Martin has written much about the history of Westeros, which gives HBO plenty of source material from which to choose a potential spinoff.

Most dedicated Game of Thrones fans already know what spinoff they’d like to see, so we’ve compiled a list of the five most likely Game of Thrones spinoffs HBO would make.

Dunk and Egg

Let’s get the most obvious spinoff out of the way first. The Tales of Dunk and Egg are a series of novellas written by George R.R. Martin set about 100 years before the main Game of Thrones series. Dunk and Egg are the nicknames for Ser Duncan the Tall and Aegon V Targaryen, two great figures in Westeros history. While Aegon would eventually become the King of Westeros, these stories are set during his youthful days when he was far down the line of succession and unlikely to become king.

Aegon met Ser Duncan at a tournament where Duncan was competing as a hedge knight. Aegon was supposed to squire for his older brother, but instead joined Duncan when his brother was too drunk to compete. Duncan later attacked another one of Aegon’s brothers (who showed signs of the Targaryen’s seemingly genetic madness) to protect an innocent girl at the tournament, leading to a costly trial by battle that ended with one Targaryen dead and two others wounded.

In the aftermath, Aegon’s father (another future king of Westeros) agreed to let Aegon squire for Duncan as they traveled across Westeros, living simply and teaching Aegon the values of humility.

Although both Duncan and Aegon died long before the events of Game of Thrones, their presence can still be felt on the series. Aegon’s older brother Aemon eventually joined the Night’s Watch and counselled Jon Snow as the Maester of Castle Black. One of Duncan’s descendants is likely Brienne of Tarth, although their exact connection is unclear.  

Unlike the often cataclysmic events of Game of Thrones, the Tales of Dunk and Egg are deliberately small in scope. Watching Dunk and Egg’s adventures among the smallfolk of Westeros would be a welcome contrast to the current series, which makes it likely HBO’s top choice for a spinoff. 

Robert’s Rebellion

If HBO didn’t want to stray too far into Westeros’s past, a spinoff could involve the events of Robert’s Rebellion, which set the stage for the main Game of Thrones series. Robert’s Rebellion began when Rhaegar Targaryen, the crown prince of Westeros, “kidnapped” Lyanna Stark, Ed Stark’s younger sister. When Ed’s older brother and father went to King’s Landing to demand Lyanna’s safe return, the Mad King Aerys murdered both of them in the throne room. 

Ed and his best friend Robert Baratheon rebelled against the king, leading to a short-lived but bloody war. Robert and Ed recruited the Tullys and the Arryns to his cause and battled against the Targaryen, Tully, and Dornish forces. Robert slew Rhaegar in the decisive Battle of the Trident, while Jamie Lannister betrayed the Targaryens and killed Aerys in his throne.

Robert’s Rebellion would feature many familiar Game of Thrones characters and would help flesh out the background of the main series. However, we’ve already seen several of the events (including the pivotal fight at the Tower of Joy) in the main series, so it might feel like treading too much already covered ground. 

Dance of the Dragons

The greatest conflict in Westeros took place hundreds of years before the Game of Thrones series. The Dance of the Dragons was a brutal civil war that led to the deaths of thousands and saw the last great dragons meet their demise. 

The Dance of the Dragons began due to a disputed chain of succession, which led to both Rhaenyra Targaryen and her half-brother Aegon II claiming the throne for themselves. Various houses chose sides, leading to a bloody conflict that lasted three years. Both Aegon and Rhaenyra had multiple dragons to command, leading to several bloody aerial battles that often resulted in the death of multiple dragons.

The Dance ended with both Rhaenyra and Aegon dead and their surviving children marrying to end the feud once and for all. The Dance of the Dragons nearly destroyed Westeros. Large parts of the land were ravaged by dragonfire, multiple cities and villages were wiped from the map, and thousands of people were dead. 

If HBO thought that dragons were the most marketable part of Game of Thrones, the Dance of the Dragons would be their most likely spinoff choice. The only problem is that CGI dragons aren’t cheap and HBO wouldn’t have the option of keeping them away from multiple episodes. 

The Targaryen Conquest

Long before Game of Thrones, the seven kingdoms of Westeros were actually seven seperate kingdoms. When Aegon the Conquerer and his sister-wives landed at King’s Landing, he began a surprisingly swift invasion that resulted in most of Westeros falling under his rule. 

The Targaryen Conquest marks the beginning of Westeros’s modern history and sets the stage for how we see Westeros today. Each of the seven kingdoms dealt with the Targaryen Conquest differently. The people of Dorne resisted via a prolonged guerilla battle, the Starks saw the futility of fighting an army with dragons and voluntarily surrendered, while the Lannisters lost their armies to dragonfire.  

The Targaryen Conquest has its share of intrigue and bloodshed, but it might be a bit too short to be anything more than an HBO miniseries. There’s also a certain inevitability to it, since we know that the Targaryens eventually unite the Seven Kingdoms under their rule. 

The Long Night

If Game of Thrones really wants to dig into Westeros’s ancient past, they could explore the Long Night that marked the White Walkers’ first excursion into the North. The Long Night occured during the Age of Heroes, a distant age where facts and myths blur. While no one knows what caused the Long Night, the legends agree that night covered the entire world for nearly 20 years.

During that time period, the White Walkers invaded the North, driving back the First Men (the ancestors of the Starks and the Northmen) and the Children of the Forest south. It wasn’t until the first members of the Night Watch, along with the “last hero” (who may be related to Azor Ahai, a mythical figure who may or may not be reborn as Jon Snow or another Game of Thrones character) drove the White Walkers back and built the Wall to keep them out.

Since the Long Night is known only in legends, HBO would have plenty of room to explore and expand the Game of Thrones mythos without being bound to book canon. Plus, we’d get more White Walkers, wights, and wintery settings, all of which are hallmarks of HBO’s Game of Thrones series.
