As part of that, Deadline has heard that the third season has already been mapped out and may be greenlit, with HBO seriously considering moving forward with scripts, casting and a production plan as the network also tries to think long-term rather than from season to season. With some of the plot originally intended for the second season, including a big fight, moving to the third season, it's now more likely that the series will run for four seasons, but that hasn't been determined yet, as Condal and Martin have moved on. and again continue to spar about the number of seasons (three or four) that would be optimal to tell the full story, the sources said.
In the prequel series, the Targaryen dynasty is at the height of its power, with more than 15 dragons under its yoke. Most wealthy, real or imagined, fall from such heights. In the case of the Targaryens, their slow fall begins nearly 193 years before the events of Game of Thrones, when King Viserys Targaryen breaks a century of tradition by naming his daughter Rhaenyra heir to the Iron Throne. But when Viserys later fathers a son, the court is shocked when Rhaenyra retains her status as his heir, sowing the seeds of division in the realm.
