A Quick Guide to the Many Families of "House of the Dragon"

House Strong is another house with a significant presence in "House of the Dragon." When the series begins, Lord Lyonel Strong is King Viserys's master of laws. His children are also present in King's Landing and the Red Keep, including Ser Harwin Strong, who serves in the gold cloaks, and Larys Strong, who is a quiet observer of everything that goes on.

In episode five, viewers learn Lord Lyonel has been raised to the position of Hand of the King. Larys is Alicent's closest ally, and in episode six, we learn Harwin is the real father of Rhaenyra's sons. Larys has his father and brother killed at Harrenhal, ultimately ending his family's line. No one from the house is around by the time the events of "Game of Thrones" occur.
