Big news for Game of Thrones fans: HBO's spin-off 10,000 Ships is officially in development. As experts in George R.R. Martin's Westeros lore, we've gathered the most reliable updates on its release date, plot, cast, and more.
The enduring popularity of Game of Thrones has fans eager for more epic tales. HBO is expanding the universe with five spin-offs in development, all prequels rooted in Martin's rich history.
Among them is 10,000 Ships. Speculation turned official on May 25, 2021, when Deadline reported HBO hiring screenwriter Amanda Segel, executive producer on Helstrom and Person of Interest.
HBO hasn't set an official premiere for 10,000 Ships, but expect it no earlier than 2023. The network is focusing on House of the Dragon, slated for 2022, to give each spin-off breathing room.
This prequel, drawn from Martin's novels like The World of Ice & Fire: The Untold History of Westeros and the Game of Thrones, spotlights Princess Nymeria.
Set 1,000 years before Game of Thrones, it follows Nymeria, ruler of Ny Sar in Essos, as war with Valyria's dragon lords devastates her Rhoynar people. She leads survivors across the Narrow Sea on 10,000 ships to southern Westeros, marries Mors Martell, and establishes the Kingdom of Dorne and House Martell.
With Segel crafting the scripts, casting details are forthcoming. Princess Nymeria takes center stage as the fierce Rhoynar leader from Ny Sar, battling the dragon lords of Valyria—poised to be the series' chief antagonists.
Five prequels are underway, but House of the Dragon leads the pack, chronicling the Targaryen ancestors. Co-created by George R.R. Martin, it's filming for a 2022 HBO debut. Key writers include Sara Hess (House, Orange Is the New Black, Deadwood), Vince Gerardis (Jumper), and Ron Schmidt (Digital Man, Prison Break: The Joyce Mitchell Story, Promised Land).
