House of the Dragon follows a period of House Targaryen, 200 years before the events of Game of Thrones,  in which there was a conflict between the members of the family. The show’s first season set the events in motion and introduced the characters. In the first season, we see how King Viserys is desperate for a male heir, but after the death of his wife Aemma in childbirth, the king decides to name his daughter Rhaenyra as the heir to the Iron Throne. His decision doesn’t sit all too well with his hand Otto Hightower who is suggesting the king remarries and has male heirs. The king marries Alicent Hightower, and a year after she gives birth to a son. The rest of the season follows the animosity developing between Rhaenyra and Alicent as their children get older and King Viserys gets sicker. 

Production for season two started recently but no release date has been announced by HBO. Season one of House of the Dragon is available to stream on HBO and HBO Max.
