House Velaryon will be a major player in House of the Dragon, and Steve Toussaint (who plays Lord Corlys Velaryon) broke down what sets it apart from the others.
Corlys and Rhaenys also have several children, so House Velaryon seems set up as a prosperous family in the Seven Kingdoms.
Luckily, the wait for House of the Dragon to introduce Corlys, Rhaenys, and the rest is nearly over.
House Velaryon is built on the fortune that Lord Corlys accumulated with his voyages.
