Game of Thrones author George R.R. Martin has revealed that, yes, one major book character is in House of the Dragon – we just haven’t seen them yet.
On the topic of time jumps and what House of the Dragon has skipped over so far, Martin wrote on his personal blog that Alicent has four children in the show, not three. The youngest son, Daeron, is currently off-screen and away from King’s Landing.
"Alicent gave Viserys four children, three sons and a daughter," Martin wrote. "Their youngest son Daeron is down in Oldtown, we just did not have the time to work him in this season."
Martin also pointed to "the relationship between Rhaenyra and Ser Harwin, the marriage of Daemon and Laena and their time in Pentos, the birth of various and sundry children" as examples of plotlines that could have been explored in greater detail if the time was there.
House of the Dragon has a second season in the works. Martin, however, thinks it’ll take another three seasons to wrap up the Dance of the Dragons story he told in Fire and Blood.
