Hugh Hammer
A blacksmith's bastard of Driftmark with dragonseed silver under the soot — big as the Breakbones, strong as his hammer, and owed back pay by the crown, as he mentions.
A soul born at Driftmark, sworn to The Dragonseeds.
The fuller tale
Season Two
In The Red Sowing — A smith who asked the crown for back pay now rides the Bronze Fury. Hugh Hammer, a blacksmith's bastard, masters Vermithor, the Bronze Fury — second only to Vhagar; Ulf the White stumbles drunk onto Silverwing.
Where they stand. King's Landing and Dragonstone.
Their story
A blacksmith's bastard from Driftmark, Hugh Hammer carries dragonseed silver hair under a life's worth of forge-soot — a big, strong man with a legitimate if unacknowledged claim to Targaryen blood, and a very specific grievance about back pay the crown owes him that he is not shy about mentioning at every available opportunity.
When the black council's desperate Sowing opens dragon-claiming to anyone plausible, Hugh's size and strength and blood combine to win him one of the war's great prizes — Vermithor, the Bronze Fury, once the mount of the Old King himself and among the largest and most dangerous dragons ever to answer to a rider.
How it ends for them
On the page. Knifed at Tumbleton before his crown arrived (F&B, ch. 7)
The blacksmith's bastard rode Vermithor, turned his cloak at Tumbleton, and began dreaming of a crown — smiths had worn them before, he noted. Hard Hugh died with a knife in him at Second Tumbleton, his crown still at the forge.
The series has not yet reached this stage of the war; Hugh Hammer's fate remains ahead of the current seasons.
Fire & Blood has him ride Vermithor to real prominence before turning his cloak at Tumbleton, growing openly ambitious about the crown he believes his new dragon and his Targaryen blood entitle him to — smiths have worn crowns before, he is recorded as observing. He is knifed at Second Tumbleton before that crown ever reaches him, one betrayal among several that collapse the greens' southern campaign into chaos.

Where the page and the screen part
The show has not yet reached the dragonseed campaigns where Hugh's story unfolds; Fire & Blood covers his rise and betrayal in considerably more military and political detail than the series has had occasion to dramatize.
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.
