King Jaehaerys I Targaryen (the Old King)

Played by Michael Carter, King Jaehaerys I Targaryen, also known as the Old King, had a remarkable reign that lasted nearly six decades. He ruled over a peaceful kingdom and fathered thirteen children. However, all his heirs tragically died, leading to his grandson, Viserys, ascending the Iron Throne.

King Viserys Targaryen

Paddy Considine portrays King Viserys Targaryen, the fifth ruler of the Targaryen dynasty, and the son of the Old King. After Jaehaerys’ passing, Viserys became the monarch. He married Queen Aemma Arryn, with whom he had a daughter named Rhaenyra, a pivotal character in the series. Following Aemma’s death, Viserys remarried Alicent Hightower, and together they had three children.

Daemon Targaryen

Matt Smith brings Daemon Targaryen to life, the younger brother of King Viserys. A skilled swordsman, Daemon is known for his unpredictability and knack for showing up unexpectedly. His character plays a vital role in the series as a fearless warrior. Throughout his life, Daemon faced the tragic loss of two wives but had two children with his second wife, Laena Velaryon.

Rhaenyra Targaryen

Rhaenyra, portrayed by Milly Alcock and Emma D’Arcy, is King Viserys’ first-born daughter. Her fierce and independent nature adds depth to House of the Dragon. Rhaenyra is married to Laenor Velaryon and has three children: Jacaerys, Lucerys, and Joffrey. However, rumors circulate that her children may not all be fathered by Laenor.

Rhaenis Targaryen

Often referred to as the “Queen Who Never Was,” Rhaenis (played by Eve Best) is the granddaughter of the Old King. Despite her rightful claim to the Iron Throne, her brother Viserys was chosen instead. Rhaenis married Corlys Velaryon, the leader of House Velaryon, and had two children: Laena and Laenor.

Aegon Targaryen

Aegon Targaryen, portrayed by Ty Tennant, is a self-centered prince. His grandfather’s manipulating actions to secure his position as the heir have shaped Aegon’s arrogant personality. He often neglects his duties and involves himself in political turmoil within the kingdom.

House Velaryon

House Velaryon, led by Corlys Velaryon (played by Steve Toussaint), holds significant influence in House of the Dragon.

Corlys Velaryon

Often known as “the Sea Snake,” Corlys is a wealthy man and former explorer. He commands the Velaryon navy, with his brother Vaemond serving as a commander. Corlys is married to Rhaenys Targaryen, solidifying his power at court. Although he does not always agree with the King’s decisions, his influence is undeniable. Corlys and Rhaenys have two children: Laena and Laenor Velaryon.
