Daeron Targaryen, the long-absent youngest son of Alicent Hightower and the late King Viserys, makes his debut in HBO's "House of the Dragon" season three. He arrives as the Dance of the Dragons — a bloody war of succession — intensifies between factions backing Aegon II and Queen Rhaenyra.
Unlike his siblings, Daeron was sent as an infant to Oldtown, seat of House Hightower, and is scarcely known to the royal family. He was kept far from the conflict throughout the first two seasons, mentioned only as a potential threat.
Daeron is a dragonrider bonded to a young blue dragon named Tessarion. He is Alicent's fourthborn child after Aegon, Helaena, and Aemond. His upbringing with the Hightowers sets him apart from his King's Landing-raised siblings.
His introduction reshapes the war's dynamics, adding a new dragon and commander to the Green faction. The show is in its third and penultimate season, adapting the Targaryen civil war from George R.R. Martin's "Fire & Blood."
The series continues to wrestle with a tangled family tree, complicated by the dragonlords' incestuous lineage. Early reactions suggest Daeron's arrival may shift momentum in the conflict's next phase.
