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.
Vhagar snatched Lucerys off his dragon's back and swallowed him whole.
In the show, Daemon Targaryen (Matt Smith), Rhaenyra's husband (and uncle), hired the assassins to target Aemond Targaryen (Ewan Mitchell), Viserys and Alicent's second son. Aemond was responsible for the death of Rhaenyra's second son, Lucerys (Elliot Grihault).
Rhaenyra had 3 sons during her marriage wih Laenor i.e Jaacerys (The one that flew to the north), Lucerys (God rest his soul, RIP Luke) and Joffry (the one Jace wos carrying during Luke's funeral, yeah..)
Daemon told her Luke was dead at the end of the episode. I presume he learned via raven when parts of Arrax started showing up on the shore over there, people must've put 1 and 1 together. There's no dialogue but that's what the scene at the end of S1 implies and that's what compells her to start looking for his body.
There's no single "saddest" death, but Hodor, Shireen Baratheon, and Ned Stark are consistently cited due to their tragic innocence, shocking betrayal, or profound thematic weight, with Hodor's mind-bending sacrifice ("Hold the door") and Shireen's burning by her own father often topping lists for sheer emotional devastation, while Ned's execution defined the show's brutal realism.
Daemon Targaryen died on the 22nd of the fifth month and Rhaenyra Targaryen died the same day, 5 months later. #HouseOfTheDragon #Rhaenyra #Daemon. The fact that there are fans who think Daemon survived a fall from *probably* 1,000 feet into water is wild.
After Viserys declared Rhaenyra as his rightful heir, the furious Daemon left for Dragonstone and took Mysaria with him. They remained there for six months, during which time Mysaria became pregnant; when Daemon learned of her pregnancy, he gave her a dragon egg, and by that infuriated Viserys.
We all know that all Rhaenyra's kids are all capable rulers. Jacaerys is diplomatic and a tactician. Not to mention that 2 of Rhaenyra's kids became kings. Viserys II is considered to be one of the greatest kings in Westeros next to Jaehaerys and the Conqueror.
For their betrayal, Hugh Hammer and Ulf White infamously became known as the Two Betrayers. It was believed that the treachery of the two dragonseeds was out of avarice, as they both resent the lands that Rhaenyra gave them and that Hugh and Ulf, who have a lust for power and wealth, desired to become lords.
Alicent dies three years after Rhaenyra in "Fire and Blood."
Rhaenyra struggled to keep the smallfolk happy because she raised taxes to afford the conflict. Three years after Rhaenyra's death, Alicent is placed under house arrest because she fails to persuade her granddaughter to kill Rhaenyra's last surviving son.
For the Two Betrayers it's simply a combination between greed for wealth and lust for powers. They aware that their dragons were bigger than everyone else besides Vhagar. Only their fears of Daemon revenge and hope for promotion made them think twice before betray the Half Year Queen.
Game of Thrones' Drogon chose not to kill Jon Snow because of his Targaryen blood, his love for Daenerys, and Drogon's possible understanding that while Jon committed the act, he wasn't the reason for Daenerys' death at the end of Game of Thrones'.
King Aegon IV Targaryen, known as Aegon the Unworthy, is considered to be one of the worst Targaryen kings ever to sit on the Iron Throne. He sired numerous bastards, legitimizing them on his deathbed, an act that led to five Blackfyre Rebellions.
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.
Robert claimed the Iron Throne because he started the war and killed Prince Rhaegar personally. Robert also had the best claim to the throne among the rebels, being of Targaryen descent through his mother.
King Aegon V Targaryen, also called Aegon "the Unlikely" and informally known as "Egg", was the fifteenth king of the Targaryen dynasty to rule the Seven Kingdoms. He was the father of the Mad King and his sister-wife Queen Rhaella.
He's 100% in love with Rhaenyra. It's all over his dialogue, body language and the way he looks at her. He is tender with nobody else like he is with her. Even Matt Smith himself said the only 2 people Daemon loves are Viserys and Rhaenyra.
Rhaego was the son of Drogo and Daenerys Targaryen. According to a Dothraki prophecy, he would have been the stallion who mounts the world.
Rhaena is dragonless for most of the Dance of the Dragons event in the book. However, she eventually gets a dragon when one of the eggs given to her hatches. She bonds immediately with this dragon and calls it Morning. Morning's birth was considered by many to be a miracle.
After Daenerys' death in the Game of Thrones series finale, her dragon Drogon became a mystery, flying off with her lifeless body and never being seen again.
As of Season 2 Episode 7, Rhaenyra's army has at least seven flying dragons, overwhelmingly outnumbering the Greens, who have only three (with Sunfyre being too wounded to fly anytime soon).
(Spoiler)After Rhaenyra's death, Aegon-II was crowned again(it lasts for six months), during that period he says the title "queen" must belong to his mother, Rhaenyra should only be mentioned as a princess.
