Editor's Note: The following article includes spoilers for Episodes 1-4 of House of the Dragon.
New characters have been introduced into the story of Westeros' Corlys Velaryon. In Episode 4, Viserys (Paddy Considine) refers to the Velaryons as one of "the most powerful houses in the world." Rhaenyra (Milly Alcock) is expected to marry Corlys' son Laenor (Theo Nate) as an important character in the game.
History of the Velaryons
The Velaryons are one of the few families that escaped the Doom of Valyria due to the smaller island of Driftmark. They never had dragons of their own, although they raised ships when Aegon the Conqueror needed a fleet.
The Velaryons embraced the Targaryens early on, even before they took control of Westeros. When there were no closer relations for the Targaryens to wed, the two families intermarried, allowing their Valyrian blood to remain pure. Aegon the Conqueror and his sister wives, Visenya and Rhaenys
The Velaryons were often chosen as the Kingsguard's master of ships because of their close connection with the Targaryens and their nautical talents. After helping Aegon win the Blackwater Rush, Demon Velaryon became the first person to hold this position.
The Sea Snake
Corlys Velaryon, the lord of the house during the program, is known as The Sea Snake, a name taken from his famous ship. He travelled many places, including Westeros and Essos. He sailed north of the wall, hoping to reach Westeros via a ferry.
Corlys designed a ship called the Sea Snake, which took him on his most famous adventures to Essos. One of these trips allowed him to double his Velaryon fortune, and he bought twenty more ships in Qarth, which were the final destination for the Velaryons, who were said to be the richest house in the kingdom, passing the Lannisters.
Corlys was the only child of King Jaehaerys I's oldest son, Rhaenys. Laena (Savannah Steyn) was allowed to claim the dragon Seasmoke, making the Velaryon house the only not-Targaryen house to have a dragon.
The lords of Westeros met to discuss the issue of succession following the deaths of Jaehaerys I's sons. Rhaenys was chosen as Jaehaerys I's oldest grandson, while Viserys was only a daughter. Corlys never recovered from the blow to his pride.
Corlys offered his young daughter as the new queen after Viserys refused to take action against the Crabfeeder who slain a Velaryon ship in the Stepstones. Even after Viserys learned Corlys was planning to marry his daughter and heir, he decided it was time to strike a truce.
The Future of House Velaryon
The Velaryons fell from grace as a result of their loyalty to the Targaryens. During Robert's Rebellion, they were allowed to keep their land until the war ended, but they lost their court position. Stannis Baratheon, the new Lord of Dragonstone, is assumed to be their primary enemy in the War of Five Kings.
If HBO decides to do a spinoff show The Sea Snake, which would focus on Corlys Velaryon's backstory, the Velaryon family will grow in importance to the House of the Dragon series.
