Just because Game of Thrones is ended, doesn\u2019t mean that HBO is done with Westeros. We know that a prequel series is incoming for the show, but a second spinoff is said to be in the works. What\u2019s more, it's focused on House Targaryen and it has\u00a0Game of Thrones creator George R.R. Martin directly involved.\r\n\r\nAccording to Deadline, Martin and Ryan Condal (Colony) are working on a prequel set 300 years before the War of the Five Kings, and it will focus on the beginnings of House Targaryen. HBO has declined to comment on the show, but it\u2019s said that the series will be based on Martin\u2019s Fire & Blood book.\r\n\r\nThis is actually just one of many other prequels in development. Martin had teased in his blog back in May:\r\n\r\n\u201cWe have had five different Game of Thrones successor shows in development at HBO, and three of them are still moving forward nicely\u2026\u201d\r\n\r\nTwo other shows remain in the script stage, but are edging closer\u2026 What are they about? I cannot say. But maybe some of you should pick up a copy of Fire & Blood and come up with your own theories.\u201d\r\n\r\nWhile I can understand a full prequel based on Westeros before the wall and a show about the rise of the Targaryens, I can\u2019t imagine what else they can based a spinoff on. Since we basically know where everything ends, I guess I would love to see a sequel series showing us what happens to Westeros after Bran\u2019s rule. Maybe in a way, it can redeem the last season. If anything, I\u2019ll be happy with a \u00a0TV movie and not a full on new series.\r\n\r\nNo release date has been set for these Game of Thrones spinoffs, but hopefully we get something as soon as 2021.
