House Targaryen
The dragonlords of old Valyria, kings of Westeros for near two hundred years — though the last dragon died a generation ago. Good King Daeron II rules a realm at peace; his brood of sons and grandsons — Baelor, Aerys, Rhaegel, Maekar, and theirs — crowd the succession, and the realm counts on the best of them.
The fuller tale
By the reign of Daeron II the dragons have been grounded a generation — the last of them died wild and unridden years before this king was born — and what the family rules with instead is paperwork, marriage contracts, and a great many sons. That last item is less a comfort than a hazard: a dynasty that spent two centuries worrying about running out of heirs now has the opposite problem, a crowded nursery of princes with real claims and no particular use for most of them, and the entire era of Dunk and Egg is, underneath its tourneys and weddings, the sound of that arithmetic working itself out.
Daeron II himself is the reign the smallfolk actually got lucky with — a scholar-king who ended a century of Dornish wars by putting a ring on a Martell princess instead of another army in the Red Mountains, and who is called the Good with a straight face by people who remember his father. The peace costs him the closed ranks of his own court: rumor has long insisted that Daeron is not truly the trueborn son his birth certificate claims, but the child of his mother's affection for a Targaryen prince other than her husband, and that whisper does more to fuel the Blackfyre claim across the narrow sea than any army Aegon IV's bastard son ever raised on his own account.
His eldest son and clearest answer to the succession was Baelor Breakspear, Prince of Dragonstone and his father's Hand for years before he was ever meant to inherit outright — the hero who broke the black dragon's host at Redgrass Field and, twelve years later, walked onto a tourney meadow to defend a hedge knight's honor against his own kin. The mace blow that killed him there did not just cost the realm its best-loved prince; it reopened every question his birth and his reign had seemed to have settled, and put the crown back in play a full generation before anyone had planned for it.
What follows Baelor's death is less a smooth succession than a scramble dressed up as one. Aerys, the second son, takes the throne more interested in old prophecy than in old grudges and leaves little behind him; Maekar, the fourth and hardest-tempered, waits his turn with a scowl that never quite leaves his face; Maekar's own sons run the family's whole range in miniature — Aerion cruel enough to drink wildfire believing it would make him a dragon, Aemon devout enough to refuse a crown twice over for a maester's chain — until the succession's last surprise turns out to be the fourth son of a fourth son, a boy who spent his adolescence pretending to be nobody in particular.
None of this looks, from inside the tales, like the hinge of a century. It looks like tourney gossip, wedding seating charts, and one very tall hedge knight trying to keep his squire fed. That is precisely the joke history plays on the family: the era's whole weight comes down not at court but on a water-meadow in the Reach and a lakeside manor in the riverlands, in rooms where the dragons themselves are only ever spoken of, never seen.
The page and the screen
A Knight of the Seven Kingdoms began its screen life in January 2026 with a season built entirely from The Hedge Knight, which means the Targaryen princes the show has actually cast and aired — Bertie Carvel's Baelor, Sam Spruell's Maekar, Finn Bennett's Aerion, Henry Ashton's Daeron — are the Ashford generation only. Aerys's quiet reign, the deeper court politics of Daeron II's later years, and the long unraveling that eventually seats Egg on the throne live for now almost entirely in the novellas and in George R. R. Martin's separate history writing, material no announced season has yet reached.
