Despite not featuring at all in Game of Thrones, House Velaryon is one of the most important families in House of the Dragon, and many of its members are key players in the lead-up to the civil war known as The Dance of the Dragons. Similarly to House Targaryen, the Velaryons also hail from Old Valyria. Unlike their distant kin, they are not dragonlords and instead derive their power from the sea.
