The end of Game of Thrones did not close the door on the Seven Kingdoms. Years after the original series wrapped, HBO continues to build on George R.R. Martin’s sprawling fantasy universe, drawing viewers back with new stories set across different eras and regions. With A Knight of the Seven Kingdoms now underway and another season of House of the Dragon on the horizon, the franchise shows no signs of slowing down.
While several proposed projects have quietly faded over time, multiple spinoffs remain in active development. Each promises a fresh angle on familiar lore, offering fans a chance to revisit legendary figures, distant lands and pivotal moments that shaped the world seen in the original series.
1. Aegon’s Conquest
The Targaryen dynasty is once again at the center of HBO’s plans. A project centered on Aegon Targaryen’s unification of Westeros remains in development, exploring the origins of the family that would later dominate the Iron Throne. The story traces how Aegon and his dragons brought the Seven Kingdoms under a single rule, laying the foundation for centuries of power and conflict.
The character has long hovered over the franchise as a legendary figure, referenced throughout Game of Thrones and given new context in House of the Dragon. Later series established that Aegon’s campaign was driven not only by ambition, but also by a belief that a united realm was necessary to face a looming existential threat. That motivation provides a rich narrative starting point for a spinoff that blends conquest with prophecy.
2. The Golden Empire
One of the most mysterious projects still in the works is The Golden Empire, which would mark two major firsts for the franchise. It is set to be the first animated Game of Thrones spinoff and the first to venture entirely outside Westeros. Despite its animated format, the series is intended for adult audiences and would retain the political depth and complexity fans expect.
The story is expected to focus on Yi Ti, an ancient and powerful empire located in Essos. Known in the lore for its wealth, rigid hierarchy and long history, Yi Ti offers fertile ground for intrigue and power struggles. By moving beyond familiar locations, the series could explore universal themes of ambition and control while standing apart from the Targaryen-centered narratives.
3. The Sea Snake
Another animated project reportedly in development centers on Corlys Velaryon, a character already familiar to viewers of House of the Dragon. Known as the Sea Snake, Corlys earned his reputation as one of the greatest sailors and explorers in Westerosi history. His voyages took him across the known world, amassing wealth and influence that rivaled even the great houses.
Originally envisioned as a live-action series, the project has since been reworked into an animated format. This shift allows for expansive storytelling that can fully capture the scope of Corlys’ travels, from distant ports to dangerous seas. The focus on exploration rather than court politics offers a different rhythm from previous series while remaining rooted in the same world.
4. Ten Thousand Ships
Ten Thousand Ships takes audiences far from the Iron Throne and into the story of Princess Nymeria of the Rhoyne. After her people were defeated by the Valyrian Freehold, Nymeria led a massive fleet in search of a new home, eventually settling in Dorne. Her journey became one of the most significant migrations in the franchise’s history.
The project emphasizes leadership, survival and reinvention, centering on a powerful woman whose legacy still echoes in Westeros centuries later. Although the series was once believed to be shelved, it has since regained momentum with new creative leadership attached, signaling renewed confidence in the story.
What comes next for the franchise
Together, these projects highlight HBO’s commitment to exploring different corners of the Game of Thrones universe. Rather than revisiting the same conflicts, each spinoff focuses on a distinct era or perspective, broadening the scope of the saga.
As development continues, fans can expect the world first introduced in 2011 to keep evolving, proving that the stories of Westeros and beyond are far from finished.
