Ulf the White’s fate was supposed to be settled history. George R.R. Martin wrote his ending in “Fire & Blood” years ago, complete with a title, a fate, and a tidy place in the Dance of the Dragons’ aftermath. House of the Dragon’s season 3 finale threw most of that out, leaving one of the show’s newest characters heading into its final season with genuinely no clear path forward.

What actually happens to Ulf in the show
Ulf the White’s fate in House of the Dragon’s season 3 finale centers on a double betrayal. According to ScreenRant’s breakdown of the Battle of Tumbleton, Ulf, played by Tom Bennett, turns against Rhaenyra’s forces during the battle — but unlike his book counterpart, he does so alone, with fellow dragonseed Hugh Hammer remaining loyal to the Blacks throughout the fight.
The show establishes Ulf’s motivations differently than the source material as well. According to Wiki of Thrones’ coverage, Ulf’s turn against Rhaenyra wasn’t really about a hunger for power, unlike the book’s framing — the show built his resentment around smaller, more personal grievances, including Rhaenyra’s camp reportedly not even allowing him “one (1) ale with the lads,” a detail that gives his eventual betrayal a pettier, more human motivation than the book’s more calculated version of the character.
How that differs from his book counterpart
Ulf the White’s fate diverges from Martin’s “Fire & Blood” in ways that go well beyond just how the battle plays out. In the book, according to ScreenRant’s reporting, Ulf and Hugh Hammer are known together as the “Two Betrayers,” both turning on Rhaenyra during the First Battle of Tumbleton and handing the Greens two additional dragons in the process — a joint act of treachery that becomes one of the more infamous turning points in the entire Dance of the Dragons.
The book’s version of events continues well past that betrayal, too. ScreenRant’s coverage notes Ulf is eventually named Lord of Bitterbridge by Daeron Targaryen as a reward for switching sides, though he’s reportedly unhappy even with that outcome. He remains aligned with the Greens alongside Hugh, and the two men’s continued demands for more power and status eventually cause a split within the Green army itself, leading to the formation of a splinter group called the Caltrops — none of which the show has set up, given how differently it’s handled Ulf and Hugh’s individual arcs.
“Ulf’s death in Fire & Blood comes shortly after the Battle of Tumbleton… but the second, not the first,” ScreenRant noted, highlighting just how much the show’s restructured single battle has already broken from the book’s original two-battle sequence.
Why the show changed his story at all
Ulf the White’s fate was reworked, according to Collider’s analysis of the change, largely to give both him and Hugh Hammer more developed, sympathetic arcs than their book counterparts received. In “Fire & Blood,” the two dragonseeds function mostly as generic, power-hungry antagonists whose betrayal serves the plot without much individual characterization. The show instead built out distinct, personal motivations for each of them — Hugh’s storyline centers on rescuing the woman he loves, while Ulf’s resentment stems from feeling disrespected and unwelcome among Rhaenyra’s inner circle.
Collider’s take on the change was largely positive, arguing that developing the two dragonseeds “ensures that they are just as interesting as any Targaryen,” and that the split betrayal — Ulf turning while Hugh stays loyal — creates a more dramatically interesting outcome than having both characters make the same choice at the same moment, even if it means departing significantly from Martin’s original account.
What his uncertain future means for season 4
Ulf the White’s fate heading into House of the Dragon’s final season is genuinely unclear in a way the books can no longer help predict. ScreenRant’s analysis pointed out the practical problem directly: Ulf “obviously isn’t remaining at Tumbleton, nor is he with Hugh the Hammer,” and given that Hugh’s wife dies over the course of the season, “it’s possible that Ulf will be among those he wants vengeance upon” once season 4 picks up the story.
That uncertainty marks a genuine shift in how closely House of the Dragon can be predicted using its source material at this stage of the story. With Ulf’s arc now diverging so significantly from the book’s Two Betrayers storyline — including the total absence of the Caltrops splinter group and Daeron Targaryen’s involvement in rewarding him — his path through the final season represents one of the more genuinely unpredictable threads heading into the show’s ending, for book readers and newcomers alike.
