The latest episode of ‘House of the Dragon’ finally confirms Addam and Alyn of Hull’s importance

In the book, both Alyn and Addam are described as having silver hair and purple eyes, hallmarks of Valyrian descent. Their mother was a woman named Marilda, who gave birth to Addam when she was 16, and Alyn when she was 18. Both of her sons served on her fleet of ships.

Marilda claimed that her sons were Laenor Velaryon’s bastards. But Mushroom, who provides one of the historical accounts referenced in “Fire and Blood,” posits that Corlys was their father instead. After Addam successfully bonded with Seasmoke, Corlys asked Rhaenyra to legitimize him as a Velaryon. She did so, making Addam Velaryon the heir to Driftmark.

As a dragonrider, Addam played a crucial part in the war. He eventually helped to claim King’s Landing for Rhaenyra, and defended it while Daemon sought out Aemond and Vhagar.

Later in the war, Addam’s fate is loosely tied to that of the other dragonriders, some of whom betray Rhaenyra. Eventually, he and Seasmoke die in a dragon fight.

Alyn of Hull becomes Corlys Velaryon’s heir

According to the book, after failing to locate the wild dragon Grey Ghost, Alyn unsuccessfully tried to claim another dragon called Sheepstealer. He was wounded in the process when Sheepstealer set his cloak aflame, but Addam and Seasmoke saved him.

Later, Corlys asserted that both Alyn and Adam were Velaryons, and suitable heirs to the Driftwood Throne. After Rhaenyra’s death, and with Corlys sequestered in King’s Landing, Alyn assumed control of the Velaryon fleet.

The TV series seems to be foreshadowing this eventual storyline with Alyn becoming Corlys’ first mate in episode six.

Eventually, Alyn became Corlys’ chosen heir. After Corlys’ death, he became the new Lord of the Tides, and eventually wed Baela Targaryen.

“House of the Dragon” season two airs Sundays at 9 p.m. ET on HBO and is streaming on Max.
