Princess Rhaenyra
The shock of the loss of her father, combined with the Greens' ruthless betrayal sends her into early labor. Without modern medicine, a baby born so early had very little chance of survival in the best of circumstances - and in these terrible conditions the baby, a girl named Visenya, is stillborn.
In 196 AC, the year of their marriage, she painstakingly produced a set of twins, Aegon and Aella. Another set, Visenya and Valarr, came in 197 AC. After her troubled deliveries, it was said Rhaenyra had nearly beaten a serving girl to death for having claimed the princess would die in labour.
When finally did give birth to the baby, it is said that the child had a hole where her heart should have been, a tail, and scales for skin—a monster, as her mother had cursed her to be. Upon her death, Rhaenyra swore yet another vow. “She was my only daughter, and they killed her.
In the book, Visenya was described as being born with dragon-like defects, including scales, a tail, and a twisted body. Rhaenyra's baby did end up having scale-like defects and a malformed body in House of the Dragon, which aligns with the occasional reports of Targaryen women bearing dragon-like stillborn children.
In Fire & Blood, the book House of the Dragon is based on, Daemon and Rhaenyra go on to have two boys: Aegon and Viserys. Yup, another Aegon and another Viserys. They also have a daughter, Visenya, but she is sadly a stillborn baby.
So, who is the real father of Rhaenyra's children? In the show and in George R.R. Martin's Fire and Blood novel, it is heavily implied that Ser Harwin Strong, a knight and the captain of the City's Watch, is the true father of Jacaerys, Lucerys, and Joffrey.
A second followed in episode six, when Rhaenyra (Emma D'Arcy) gives birth to Joffrey. In episode 10, Rhaenyra, shortly after learning her father King Viserys (Paddy Considine) has died, goes into early labour, which leads to her baby being stillborn.
Regardless of this, Rhaenyra's pregnancy was soon announced, and in the waning days of 114 AC she gave birth to their first child. Laenor wished to name the child Joffrey, but was overruled by his father, who named the boy Jacaerys. Rhaenyra gave birth to a second son a year later, who was named Lucerys.
Daemon shows wife Rhaenyra the message; she recognizes that if Luke's claim to the title is questioned, so could the legitimacy of her three sons with Harwin Strong. Daemon puts a hand on Rhaenyra's belly. She is pregnant with their child.
Firstborn son of Rhaenyra and her first husband Laenor Velaryon, Jacaerys was affectionately known to his family as Jace. There were abundant rumors spread by Queen Alicent about the legitimacy of Jace's parentage, with murmurs circulating through court that his true father was Ser Harwin Strong.
One of the first times we see Rhaenyra as truly angry throughout the entirety of Season 1 is during the traumatic miscarriage of her daughter Visenya.
Rhaenyra Targaryen was getting married to Ser Laenor Velaryon, last we saw her. In this episode, the first thing we see is Rhaenyra giving birth.
Rhaenyra's three eldest sons all died fighting during the Dance of the Dragons, but her two youngest sons, the sons by her second husband, Prince Daemon, survived the civil war.
Rhaenrya takes the news of her son's death none too well. The look she gives the camera upon Daemon delivering the news suggests she is ready to burn Alicent's family alive. The Season 1 finale was named “The Black Queen,” and it seems that Rhaenyra is finally ready to take on that title.
Rhaenyra and Daemon's sons Aegon, Viserys, and Visenya Targaryen. Sorry for the spoiler, but we did watch Daemon and Rhaenyra get married in last week's episode, so you probably knew this was coming! We haven't seen them yet in the show, but Daemon and Rhaenyra have three sons together.
The episode doesn't really beat around the bush when revealing that Harwin Strong (Ryan Corr) is the father of Rhaenyra's children. He's there soon after baby Joffrey is born so he can meet him, and later on in the episode Jacaerys (Leo Hart) even asks his mom if Harwin is his real dad.
Rhaenyra's baby died during childbirth.
We only briefly see Visenya in the TV series, but Fire and Blood, the book House of the Dragon is based on, gives a detailed description of the malformed baby. According to the book Visenya, like Maegor the cruel's children, was born with scaled dragon-like skin and a small tail.
Rhaenyra, recalling the death of her mother in childbirth, refuses help from her maidens as the pregnancy wreaks havoc on her body. Knowing something is wrong, she gives birth all by herself.
According to Mushroom, Princess Rhaenyra had cursed Visenya while giving birth, calling her a monster. He also claims that Visenya had dragon-like birth defects, describing her as having been twisted and malformed, with a hole in her chest where her heart should have been and a stubby, scaled tail.
Rhaenyra and Daemon now have two children—sons Aegon and Viserys—with a third on the way. Aegon the Elder is now married to Helaena, and it's mentioned that they have children. It isn't clear exactly which kids they've had yet, but in the books they have three: Jaehaerys, Jaehaera, and Maelor.
Rhaenyra Targaryen (Emma D'Arcy) and Daemon Targaryen (Matt Smith) finally had sex on House of the Dragon. After teasing their deep connection for weeks, making out in a brothel, and flirting their way through King's Landing, uncle and niece at long last did the dirty.
Rhaenyra has been pregnant with her daughter Visenya since House of the Dragon's latest and last time jump, and it is heartbreaking to see her deal with this loss. The way in which the scene plays out makes it especially disturbing.
Rhaenyra's sixth pregnancy in House of the Dragon sets up one of the most utterly tragic moments still to come. House of the Dragon frequently emphasizes the dangers of childbirth and pregnancy for women in Westeros, with the two major characters Laena Velaryon and Aemma Arryn already dying from such complications.
