The world of Westeros is about as detailed as you can get when it comes to fantasy storytelling. You could spend longer reading wiki entries about Game of Thrones than you would take reading the books or watching the actual show. With such an expansive setting to explore, the franchise could have gone anywhere once the flagship series came to an end. The sky was the limit in terms of where they could have gone next. Which is what makes A Knight of the Seven Kingdoms so refreshing.
Initially, a number of ideas came and went until HBO eventually settled on House of the Dragon, which is essentially another version of Game of Thrones in all but name. It's set 200 years prior, which means new characters come to the fore, but this is still a familiar story of warring houses and palace intrigue, complete with the usual sex, violence, and dangly bits that Game of Thrones once made feel so novel.
