What is dead may never die on Game of Thrones.

HBO's juggernaut fantasy epic ended just a few years ago, but there are already so many prequel spin-offs in development (or rumored to be in development) that we'll never truly be without the stories of Westeros, long after the Mother of Dragons' murderous rampage ended in the series finale. Spin-offs are coming, and while you nothing (Jon Snow) about them yet, we've got the details!

Here are all the Game of Thrones spin-offs that are currently in development and everything we know about them so far — because EW always pays it debts.

House of the Dragon

Since the first planned prequel series starring Naomi Watts (set 10,000 years before GOT) was not picked up by HBO, House of the Dragon will be GOT's first spin-off — and the only one currently, officially greenlit. All 10 episodes have been filmed, according to George R.R. Martin, who has seen "rough cuts" of a few. "And I'm loving them," he said on his Live Journal blog. "Of course, a lot more work needs to be done. Special effects, color timing, score, all the post-production work. But the writing, the directing, the acting all look terrific. I hope you will like them as much as I do."

Set to launch this year, this prequel series tells the story of the Dance of the Dragons, the bloody House Targaryen civil war that took place hundreds of years before the beginning of GOT. Based on Martin's 2018 novel Fire & Blood about the full history of House Targaryen, this series will only focus on the Dance of Dragons war specifically. And while the war is over which Targaryen descendent will succeed King Viserys as head of House Targaryen after his death, the Dance of Dragons also features armies consisted of forces from Lannister, Stark, and other recognizable GOT houses. 

House of the Dragon stars Fabien Frankel as Ser Criston Cole, a Kingsguard knight. Martin described the character of Cole on his blog: "He is a lover (or is he?), a seducer (or is he?), a betrayer (or is he?), a breaker of hearts and a maker of kings." Emma D'Arcy (Truth Seekers) will play Princess Rhaenyra Targaryen, Olivia Cooke (Ready Player One) will play Queen Alicent Hightower, Paddy Considine (Peaky Blinders) will play King Viserys I, Matt Smith (The CrownDoctor Who) will play Prince Daemon, Sonoya Mizuno (Devs) will play Mysaria, Rhys Ifans (Notting Hill) will play Ser Otto Hightower, Steve Toussaint (Prince of Persia: The Sands of Time) will play Lord Corlys Velaryon aka the Sea Snake, and Eve Best (Nurse JackieThe King's Speech) will play the Sea Snake's wife, Princess Rhaenya Velaryon aka "The Queen That Never Was."

Martin serves as a co-creator of the prequel, and while GOT writer and co-executive producer Bryan Cogman originally developed the concept for House of the Dragon, he exited the project and writer Ryan Condal (Colony) and director Miguel Sapochnik (who directed iconic GOT episodes like "Hardhome" and "The Long Night") will serve as showrunners instead.

The Sea Snake

News broke in March 2021 that HBO is reportedly making three more spin-off series, with The Sea Snake, formerly titled Nine Voyages, the furthest along in development (representatives for HBO declined to comment). Martin revealed on his blog that the name change came about because "we wanted to avoid having two shows with numbers in the title."

This prequel would focus on Corlys Velaryon aka the Sea Snake, known as the greatest seafarer in the history of GOT's Seven Kingdoms. If that name sounds familiar to you, well, it should. As noted above, Steve Toussaint is playing that character in House of the Dragon. How will Toussaint pull double duty on both spin-offs, and how much overlap will there be? We'll have to wait to find out the answers to those questions, much like we keep on waiting for Martin to finish writing The Winds of Winter (which he promises he's still working on, but we'll believe it when see it!).

What we do know is that The Mentalist creator Bruno Heller — who was previously reported to be pitching GOT spin-off ideas to HBO like a prequel based on Robert's Rebellion aka the war for the Iron Throne mentioned all the time on the original series — is currently writing the pilot script for The Sea Snake.

Ten Thousand Ships

Another project reportedly in development at HBO is set about 1,000 years before the events of GOT and would follow Princess Nymeria, an ancestor of House Martell who founded Dorne. Known as a true warrior, she was such an iconic figure in the world of GOT that two characters from the original series — one of the Sand Snakes Nymeria Sand (Jessica Henwick), as well as Arya's (Maisie Williams) direwolf — were named after her.

According to Martin, the working title of this prequel is Ten Thousand Ships, named after the military move in which Nymeria ordered all her ships to be burned after her army traveled from Essos to Dorne so turning back was not an option (the name of this series is why Nine Voyages is now titled The Sea Snake). Martin also revealed that Amanda Segel is the showrunner and has already delivered "a couple drafts" of scripts and they are "forging ahead" on this series.

The Tales of Dunk and Egg series

HBO is also reportedly developing a series based on Martin's Tales of Dunk and Egg novellas about iconic knight Ser Duncan the Tall (Dunk) and his squire (Egg) — who is destined to become King Aegon V Targaryen. This prequel is set 90 years before GOT and is helmed by Steve Conrad. "He's determined to do a faithful adaptation of the stories, which is exactly what I want; these characters and stories are very precious to me," Martin said on his blog. "The first season will be an adaptation of the first novella, The Hedge Knight."

The series will not be named after the title of the novellas, however. Martin revealed that the working title is currently A Knight of the Seven Kingdoms, with The Hedge Knight also in consideration. "Contrary to what you may have read online, the show will not be called Dunk & Egg, which could be mistaken for a sitcom by viewers unfamiliar with the stories," Martin added.  

Rumored Flea Bottom series

Another prequel reportedly in development is set in Flea Bottom, the King's Landing slum featured in the original series, where the poorest residents of the Westeros capital live. No other information has been revealed yet.

The Golden Empire and other animated series

These spin-offs are most shrouded in secrecy, but thankfully Martin is giving little bits and pieces of information about what fans might be able to expect from the rumored animated GOT series, beginning with The Golden Empire (working title).

"I am not allowed to talk about most of what's happening, except to say that things are moving very fast, and I love love love some of the concept art I am seeing," he said on his blog. "The news leaked several months ago that one of the animated shows would be set in Yi Ti. That's true. Our working title is The Golden Empire, and we have a great young writer on that one too, and I think the art and animation is just going to be beautiful. I would tell you more if I could. I don't think I can say a word about the other animated shows. Not yet."

The legacy of Game of Thrones is long and full of spin-offs. Come back here as we keep this list updated as new developments are announced.
