A soul of House Targaryen, born at King's Landing.
The fuller tale
Season One
In Ashford Meadow ÔÇö The Young Prince: Baelor's heir, a champion by birth more than by lance. The champions take the field: Lord Ashford's two sons, Ser Humfrey Hardyng, Ser Tybolt Lannister, and Prince Valarr Targaryen, the Young Prince. In A Knight of the Seven Kingdoms ÔÇö The Young Prince inherits Dragonstone ÔÇö and none of his father's greatness. The realm's future dies with him: the succession now runs through sickly Valarr, and the good years of Daeron's reign begin their long ending.
Where they stand. Ashford Meadow and King's Landing.
How it ends for them
On the page. Taken by the Great Spring Sickness (TSS, ch. 1)
The Young Prince survived Ashford only to die two years later in the Great Spring Sickness, with his own young sons beside him ÔÇö and the crown that should have been Baelor's line's passed sideways, to Aerys.
Two years after Ashford Meadow, the Great Spring Sickness that kills his grandfather King Daeron II also claims Valarr, along with his own young sons at his side ÔÇö a single plague erasing, in one season, an entire branch of the succession that the realm had assumed was settled. What should have been a clean line from Daeron to Baelor to Valarr to ValarrÔÇÖs heirs instead collapses entirely, and the Iron Throne passes sideways to Aerys, DaeronÔÇÖs surviving second son, in a succession nobody at Ashford Meadow had any reason to plan for.

Where the page and the screen part
Valarr appears in the showÔÇÖs first season as part of the tournamentÔÇÖs aristocratic backdrop rather than as a heavily featured player, consistent with his function in the source novella ÔÇö a recognizable name and face among the champions of Ashford Meadow rather than a figure the plot turns on. Casting details for the role have not been widely publicized alongside the seasonÔÇÖs headline names, which fits a character whose narrative weight in The Hedge Knight itself is more symbolic than active.
Their journey
Where the two tellings send them to the same place the road runs whole; where they part, the screen keeps the left and the books the right.
