HBO is actively developing a spin-off centered on Arya Stark, though details remain scarce.

• It is one of several projects that could move to production depending on the success of A Knight of the Seven Kingdoms

Seven projects in development, one pattern: HBO is keeping its options open but only committing to projects with a clear creative vision. The implication: the next spin-off after Knight may depend entirely on how that series performs.

HBO is playing a long game with the Game of Thrones franchise. After the original series ended, the network greenlit a wave of spin-offs, but only two made it to air — and one of those, Bloodmoon, was scrapped after spending $30 million on a pilot. The Jon Snow sequel failed to find a story worth telling, leaving House of the Dragon as the sole active series for now. For HBO, the bet is clear: invest in proven prequels like A Knight of the Seven Kingdoms to maintain the franchise’s momentum, or risk losing the audience that made Game of Thrones a phenomenon. Fans should expect a steady, careful rollout — not a flood.
