And despite not having a single character officially revealed at this point in the process, if House of the Dragon is going to focus on the Targaryen civl war, often referred to as the Dance of Dragons, then characters like King Viserys I, Princess Rhaenyra Targaryean, Prince Daemon Targaryen, and Aegon II Targaryen would ideally be included in the upcoming series.
The June update from George R.R. Martin on the writing process wasn’t the only update we received this summer as EW published a report in July 2020 that the casting process for the series had reportedly gotten under way.
Although no details were provided on the roles the showrunners were looking to fill or when shooting would get started, just the news of a reported casting call is major news for the HBO fantasy series.
