HBO developing THREE new Game of Thrones spin-offs which may cross over with House of the Dragon

While HBO is still casting its Game of Thrones spin-off House of the Dragon, the cable network has put three more spin-offs into development, some of which may have crossover potential with House of the Dragon.

The first show is 9 Voyages (which has also been called Sea Snake), which hails from Rome and Gotham creator Bruno Heller, according to Variety.

The other two shows – entitled Flea Bottom and 10,000 Ships – do not have writers attached as of yet.

9 Voyages would center on Lord Corlys Velaryon, who was known as the ‘Sea Snake’ and considered the best nautical adventurer in all of Westeros.

He was the head of House Velayron, which had more wealth than even House Lannister, amassing the greatest naval fleet in the world.

What’s intriguing is HBO has already cast Stephen Toussaint as Corlys Velaryon in House of the Dragon, so it’s possible he could have double duty in both shows.

Eve Best has also been cast as Corlys’ wife, the dragonrider Princess Princess Rhaenys Targaryen, who could also potentially appear in both shows.

The second  spin-off, Flea Bottom, would take place among the poorest of all the districts in the slums of King’s Landing.

The third and final spin-off, 10,000 Ships, centers on Princess Nymeria, who journeyed with the Rhoynar to Dorne and married Lord Mors Martell.

HBO is already well under way with casting on House of the Dragon, which is set 300 years before the events of the Game of Thrones series and books by George R.R. Martin.

House of the Dragon, based on the book of the same name by Game of Thrones author George R.R. Martin, explores the history of House Targaryen, the dragon-riding family that controlled Westeros for centuries.

Paddy Considine is playing King Viserys Targaryen, Matt Smith as his younger brother Prince Daemon Targaryen, Emma D’Arcy as Princess Rhaenyra Targaryen, the king’s firstborn, Olivia Cooke as Alicent Hightower, daughter of Otto Hightower, who serves as Viserys’ Hand of the King and Sonoya Mizuno as Mysaria, who came from nothing to become a trusted ally to Prince Daemon.
