That extinction isn’t permanent though, as Game of Thrones fans already know. In fact, the civil war results in the deaths of most of the world’s living dragons - with the species going extinct just 24 years or so after the end of the Dance of the Dragons.
Of course, that won’t last forever, as the Dance of the Dragons does have a lasting and negative effect on House Targaryen. As a result, House of the Dragon has the chance to present casual fans with a somewhat different power structure than the one they became familiar with over the course of Game of Thrones’ eight seasons. Indeed, where Game of Thrones began with both the Targaryens and their dragons all but extinct, House of the Dragon starts with the family near the height of its powers. There are also a number of dragons still alive and kicking at the start of the series. Robert’s Rebellion, which saw familiar Game of Thrones figures like Ned Stark and Robert Baratheon successfully oust the Targaryen family from the Iron Throne, won’t happen until 150 years or so after the events of House of the Dragon.
Next, to the normal building materials, you will also need Dragon Secrets to upgrade your Dragon Pit. When House of the Dragon begins, House Targaryen still rules (fairly) securely over Westeros. One major part of Game of Thrones Conquest Dragon Costs will be the Dragon pit since you have to build it starting from level 1.
