King Daeron II Targaryen
Daeron the Good: the king who joined Dorne to the realm with marriages instead of armies, and paid for it with the Blackfyre Rebellion. Bookish, mild, and stronger than his enemies ever understood — the peace of the age is his making.
The fuller tale
Daeron the Good inherits a throne his own half-brothers believe should never have been his — whispers that his mother took a Kingsguard knight to her bed persist for decades, less because anyone can prove it than because it is a convenient story for men who would rather Aegon the Unworthy’s favorite bastard sat the Iron Throne instead. Bookish where his father was appetitive, patient where the realm expected another warrior-king, Daeron spends his reign proving that competence can be its own kind of armor even against a claim that never entirely stops being questioned.
His signature achievement is a peace bought with parchment rather than swords: marriages that fold Dorne, alone among the Seven Kingdoms never conquered by dragonfire, into the realm at last — his own match to a Dornish princess, and his sister’s to Dorne’s ruling prince, doing in a decade what a hundred years of Targaryen war had failed to manage. It is a triumph the old marcher lords never entirely forgive him for, since it puts a Dornish-blooded prince — his own son Baelor — first in line for a throne some of them still think of as a purely Andal inheritance.
The bill for his legitimacy comes due anyway, in the form of the Blackfyre Rebellion — his half-brother Daemon, legitimized by their shared father and bearing the ancestral Valyrian steel sword that should, by an older logic, have marked him the true heir, raises a black dragon banner and very nearly ends Daeron’s reign at Redgrass Field. That the day is won at all owes everything to men who are not the king himself: his son Baelor’s charge, and the pale bowman who ends the rebellion’s cause with a single, well-placed arrow.
By the time the story of a hedge knight and his squire opens, Daeron is an aging monarch presiding over a peace he built and a family he can no longer entirely control — sons competing for glory, a Blackfyre grievance still smoldering in exile, and, waiting at a country tourney he probably never expected to matter, a fight that will end his heir’s life and reopen every question his reign was meant to close.
The page and the screen
Daeron II remains offstage through the events of The Hedge Knight itself, mentioned as the distant royal authority whose peace is being tested rather than a character who appears in scenes, and the show’s first season follows the novella’s lead in keeping him a name rather than a face. Whatever screen time he eventually gets will most likely arrive if a later season adapts material set earlier — the Blackfyre Rebellion itself lies outside any of the three published novellas, told instead in the historical volume Fire & Blood, which the show has drawn on more directly for its earlier prequel.

The books: Taken by the Great Spring Sickness (TSS, ch. 1)
Daeron the Good died in the Great Spring Sickness of 209, with tens of thousands of his people — the gentle king who gave the realm Dorne and peace, gone in a season of dying that spared neither crowns nor cradles.
Daeron the Good dies in the Great Spring Sickness of 209 AC, a plague that sweeps the Seven Kingdoms indifferent to crowns, carrying off tens of thousands of his subjects in the same season it takes him. It is a death with no drama in it at all — no battle, no betrayal, just a fever that does not care whom it kills — and its timing could hardly be crueler: it follows within the same year as his heir Baelor’s death at Ashford Meadow, so that the peace Daeron spent a reign assembling loses both its architect and its intended successor within months of each other.
