House of the Dragon Cast and Character Ages and Heights Explained

House of the Dragon is an American television series that falls into the genre of fantasy drama.

It is a prequel to HBO’s most-watched television series of 2019, Game of Thrones. Currently, HBO’s most-watched television series is House of the Dragon.

House of the Dragons is one of the most famous shows of 2022, but it is also very confusing.

Throughout the season, there are several major and minor time jumps from one significant event to another.

With these time jumps, the characters are also aging, making it hard for us to keep track of how old each character is getting as the show progresses.

In episode 2, “The Rogue Prince,” Rhaenyra’s father, Viserys, mentions she is 15.
Later, in episode 3, “Second of His Name,” Viserys laments that his daughter is now 17 and must find a suitor.

There is not much information in the episodes to figure out Daemon’s age, so let’s refer to the novel “Fire and Blood.”

By the age of 18, she got married to Viserys and became his second wife. This is what the book Fire and Blood states; it also states that Alicent Hightower was born 88 years later after Aegon’s Conquest.
