Harwin
A guardsman of Winterfell, son of Hullen the master of horse, who served House Stark before the war scattered him to the Brotherhood.
A soul born at Winterfell, sworn to The Brotherhood Without Banners.
The fuller tale
Their story
Harwin is Winterfell-born and Winterfell-made: son of Hullen, the castle’s master of horse, raised among the stables and the guardsmen, one of the household faces the Stark children knew before they knew their letters. When Eddard Stark rode south to be Hand, Harwin rode in his tail — and when Lord Eddard dispatched a hundred men under Beric Dondarrion to bring the Mountain to justice for his raiding, Harwin was among them. The errand outlived the government that ordered it: ambushed, broken and hunted, its survivors stayed in the field, and the Stark guardsman became, without ever exactly deciding to, an outlaw of the Brotherhood Without Banners.
The books give him the reunion the show never stages. When the Brotherhood scoops a ragged captive off the roads and hauls her to the hollow hill, it is Harwin who looks past the dirt and the boy’s clothes and knows her — Arya, his lord’s daughter, whom he once led around the yard on her first pony. For a stretch of the riverlands he becomes her keeper and the closest thing to home she has touched since her father died; and it falls to him to explain, gently, what the Brotherhood now is — men sworn first to a lord and a king, both dead, who found that the realm and its smallfolk still needed defending after every banner above them had burned. No one in the tale states the story’s case for the common people more plainly, and he does it in a cave, to a child, wearing another man’s war for a cloak.
How it ends for them
The chronicle records no death for this soul — they are living when the tale leaves them, or their ending is a page the maesters have yet to turn.

Where the page and the screen part
The show cut him entirely — its Brotherhood springs up without the Winterfell thread, and Arya passes through their hands unrecognized by any old friend, which loses a quietly devastating book beat: that even at her lowest she was one familiar face from rescue, and the war’s machinery carried her past it anyway. In the published books Harwin rides with the Brotherhood still, deep in its grim later turn, his ultimate loyalties — to the band, or to the Stark girl he knew — one of the riverlands’ many unsettled accounts.

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.
