Who is Daeron Targaryen? 'House of the Dragon' finally introduces Alicent's youngest son

Many fans believe that Prince Daeron has already been hiding in plain sight

After years of references and fan speculation, House of the Dragon has finally introduced Daeron Targaryen in season 3, though not in the way viewers expected. The latest episode delivers a major twist involving the long-absent prince, setting up what could become one of the most important storylines in the Dance of the Dragons.

Daeron is the youngest son of King Viserys I Targaryen and Queen Alicent Hightower, making him the younger brother of Aegon II, Helaena and Aemond, as well as the half-brother of Queen Rhaenyra I Targaryen.

Although he has existed in George R R Martin's Fire & Blood from the beginning, the character had remained off-screen throughout the first two seasons, leading many viewers to wonder why he had never appeared.

Season 3 finally addresses that mystery, revealing that Daeron has been living in Oldtown, where he was sent as a young child to be fostered by House Hightower. However, the episode initially misleads viewers by presenting a silver-haired boy as Daeron before revealing that he is actually an impostor forced to assume the prince's identity as part of Lord Ormund Hightower's plan. The real Daeron remains hidden, preserving one of the Greens' most valuable assets.

The deception underscores just how important Daeron has become as the Targaryen civil war intensifies. Unlike many members of his family, he is described in Martin's novel as honourable, kind-hearted and level-headed. He is also a dragonrider, bonded with the blue she-dragon Tessarion, making him a significant military advantage for the Greens as they continue their fight against Rhaenyra's forces.

Although HBO has yet to officially confirm the actor portraying the real Daeron, many fans believe the prince has already been hiding in plain sight. The episode introduces Lord Ormund Hightower's quiet squire, leading viewers to speculate that he is secretly Daeron. Entertainment Weekly notes that the reveal is likely to play a major role as the season progresses.

Daeron's arrival also resolves one of the longest-running questions among House of the Dragon fans. Author George R.R. Martin previously confirmed that the character existed in the show's continuity, explaining that the first season simply did not have enough time to include him. With the war escalating and several dragons already lost, his introduction comes at a crucial point in the conflict.

As House of the Dragon moves deeper into the Dance of the Dragons, Daeron is expected to become a key figure in the Greens' campaign. Whether he lives up to his reputation as "Daeron the Daring" remains to be seen, but his long-awaited debut has already given fans one of the season's biggest surprises.
