7 Important House of the Dragon Characters To Expect In Season 3 (& How They Connect)
House of the Dragon season 3 still has more characters to introduce. Here are some key figures from the books that still need to appear on the show.
Rhaenyra Targaryen Is Daenerys' Fifth Great-Grandmother
Daenerys Is A Descendant From Rhaenyra & Daemon’s Line
Daenerys is related to Rhaenyra because she is her direct descendant from Rhaenyra’s marriage with Daemon. InHouse of the Dragonseason 1, episode 7, “Driftmark,” Daemon and Rhaenyra marry, and in episode 8, “The Lord of the Tides,“Daemon and Rhaenyra have two sons in six years. Their sons are named Aegon and Viserys. At the end of the Dance of Dragons, all of Rhaenyra’s sons are presumed dead, except Aegon. He ascends the throne as Aegon III after someone fatally poisons Aegon II.
However,Fire & Bloodlater reveals that Viserys did not die; he was just kidnapped and sold, eventually returning to King’s Landing. Aegon III dies with two sons as his heirs—Daeron I and Baelor I. However, neither king produces offspring, transferring the line of succession to Viserys. Aegon III does have three daughters—Daena, Rhaena, and Elaena. However,theGame of Thronesprequel establishes that the Dance of Dragons occurredprimarily because of male primogeniture, so Westeros passed over Aegon III’s daughters to avoid another war.Daenerys comes from Viserys' descendants, making her Rhaenyra’s fifth great-granddaughter.

How The Targaryen Line Continues From Rhaenyra’s Children To Daenerys
Viserys has three children: Aegon IV, Naerys, and Aemon. To keep Targaryen tradition, Viserys marries Aegon, his heir, to his sister, Naerys. They have two children: Daeron II and Daenerys. Daeron II has four sons, two of whom become king—Aerys I and Maekar I. When Aerys dies without children, Maekar, Daeron’s fourth son, ascends the iron throne. Maekar also has four sons: Daeron, Aerion, Aemon—who later becomes Maester Aemon—and Aegon.Maekar Targaryen and his sons will appear inA Knight of the Seven Kingdoms. By the time Maekar dies, his two eldest sons, Daeron and Aerion, have already passed.
However,A Song Of Ice And Firehas an extra generation between Aegon V and the Mad King.

An emergency council gathers to determine the next Targaryen king, initially asking Aemon to be king. However, Aemon rejects them because he has already taken the Black. Therefore, Maekar’s fourth son, Aegon V, becomes king of Westeros.Aegon V’s descendants differ inGame of ThronesandA Song of Ice and Fire.Game of Thronesmakes Aerys II and Rhaella, his sister-wife, Aegon V’s children. However,A Song of Ice and Firehas an extra generation between Aegon V and the Mad King. In the books, Aegon V has several children, none of which are Aerys or Rhaella.

After Aegon V’s eldest son, Duncan gives up the throne for love, his second son, Jaehaerys, becomes the king upon Aegon V’s death. Jaehaerys tricks his father and marries his sister, Shaera, reigniting the Targaryen sibling marriage tradition.Jaehaerys and Shaera have Aerys and Rhaella, Daenerys' parents. Therefore,A Song of Ice and Firedepicts Rhaenyra as Daenerys' sixth great-grandmother, while she remains Daenerys' fifth great-grandmother in the show’s universe.
