House of the Dragon Season 3 Finale Reveals Alys Rivers Was the Widow of Harrenhal's Last King

The House of the Dragon season 3 finale has told us something very creepy about Alys: she was the wife of Harren the Black, Harrenhal's last king, and she has been serving inside Harrenhal for 130 years. Rivers, it turns out, was never her name to begin with. I do not even want to add the surname anymore.

Later in this piece I will also get into the book lore, and a theory that links her to a man half the realm called a sorcerer.

Rivers was never Alys's name, it was done to her

Rivers is the name the realm gives a child born out of wedlock in the Riverlands, the same way Snow belongs to the North and Sand belongs to Dorne. It is not a family name, and the moment you mention it, everybody concludes you are illegitimate.

Ever since the show started, we saw Rivers as Alys's surname, telling us she was from the Riverlands. With what we have learned now, that name looks more like something that was actually done to her. This woman in Harrenhal was never a bastard of the Riverlands.

Alys was Harren the Black's wife, and Harrenhal is hers

She was mistress of the largest castle ever raised in Westeros, a castle her husband built out of torture and murdered weirwoods. She has been carrying water in it for 130 years because she loved her son too much to let him go. That suggests she is very old, probably the oldest person alive, and yet we see her as a young girl. We have been calling her a witch, and don't blame us, because everything about her suggests it. Even the maesters in the books depict her that way.

Fire and Blood does not dig too deep into what really happened at Harrenhal. Harren the Black of House Hoare finished the biggest castle in the world on the same day Aegon Targaryen landed in Westeros. Balerion came, and the line of Hoare ended in one night, sons and everything. The book does not linger on it or tell us about Harren's wife. The show has finally filled that gap, and I think it is brilliant.

Remember when Daemon spent his days at Harrenhal and Alys told him the history of the castle and the things buried beneath it? She was telling him she was the lady of the house when it was being built and the mortar was wet. When she says Harrenhal belongs to her, she means it. She is the only living person who can make a claim to it, and every lord of Harrenhal for 130 years has been a tenant sleeping in her hall.

Her burned son drove her from the maesters to older cures

We already know one of Harren's sons lived a little while after the fire, badly burned. Per this revelation, that boy was hers, and that completely changes this widow. First she summoned maesters from across the Seven Kingdoms, and they could do nothing. Only then did she turn to older cures, incantations more ancient than the land, and things that lived in the forest.

She was not a sorceress herself, just a mother with money who wanted to save her son, and she exhausted every reasonable option before looking for unreasonable ones. That is why we now see her as a sort of maester, though not a full one, who knows poultices, sleeping draughts and how to treat wounds. She dedicated years to medicine and potions. Those were her first failed attempts, yet they became part of her.

The old magic of the Isle of Faces was her neighbour

Harrenhal sits on the shore of the Gods Eye. In the middle of that lake is the Isle of Faces, where the First Men and the Children of the Forest signed the pact that ended their war, and where the green men have kept the weirwoods for longer than anyone can count. Those antlered figures have hovered at the edge of the Harrenhal woods all season, bearing witness.

So when she says she treated with things that lived in the forest, she did not have to travel far. That old magic was her neighbour, just across a lake. And this will unsettle you: what she sought actually worked. Those things heard her cries. But magic comes with a cost and its own terms and conditions.

The boy's wounds came from dragonfire, and none of it could unmake that. Dragonfire is the newer magic Valyria brought across the sea, and it is probably mightier than what was already in Westeros. That explains what Daemon said to Rhaenyra, which I have quoted before: "You answer to higher gods." The oldest power in Westeros could not undo what Balerion the Black Dread did, and the boy died anyway.

The spell fell on Alys, and now she cannot die

When she tried to follow him, she learned the cost. I would say this is the oldest rule the franchise has. Mirri Maz Duur says, "Only death may pay for life." Daenerys pays with Drogo and gets a husband who breathes and nothing else. Beric Dondarrion comes back six times and leaves a piece of himself behind each time until there is barely a man in the armour. Catelyn Stark comes back with nothing but the hate still working. "Magic is never free."

She wanted to save her son, yet the boy died and the spell was directed at her. Now she is the one who cannot die. They helped her, but when they could not help the son, they turned it on the mother, a punishment great enough to tell her you do not treat with magic without paying a hefty price. She was also cursed for sharing in Harren's avarice. She got her name, her title and her castle, and was sentenced to serve every halfpenny lord who comes to rule it.

Harrenhal's curse finally has a face

Harrenhal is supposed to be cursed. Every house that holds it withers: the Harroways, the Strongs, the Lothstons, the Whents, all gone or ruined. We always explained it with a shrug about melted stone and bad luck. Now we have someone standing at the centre of that curse, a woman sentenced to fetch and carry for men sitting in her husband's chair, who has to watch all of them die.

"Don't misquote me. I'm not saying that she kills them. I'm saying the curse isn't random at all, and she happens to be the face of it all." She is bound within the borders of the River Kings of old: Harrenhal, the Gods Eye, the Trident, the whole old kingdom. That is why we have never seen her as a factor elsewhere. She cannot go anywhere.

All of this rests on her word to Aemond

Everything I just laid out comes from the account she gives Aemond at a moment when she wanted something from him. It is the only account we have, and it cannot be verified from any archive. We are just taking her word for it.

She may be trying to win Aemond over with deceitful words, and she may be telling the truth. I bet she is telling the truth rather than lying. The tears in her eyes alone confirm it for me.

Alys wants to build her own kingdom at Harrenhal with Aemond

This is why she wants Rhaenyra to grant her Harrenhal, and why she wants Aemond beside her when she takes it. She calls herself Lady of the water. They have dragon eggs, and it now looks like they have the knowledge to wake them. Strategically, that is the correct move for someone in her position, and she has a plan.

Since she cannot leave, her best move is to stay put and build the place and the forces needed to make everyone come to her: a dragon rider, a castle she owns that nobody can take, and then dragons. She is trying to build a formidable force of the Riverlands. Those outside can fight their war; she does not care. If she succeeds, Harrenhal becomes her seat of authority, and together with Aemond she can rule from there. She does not need King's Landing when she can turn Harrenhal and the Riverlands into her own.

Why Aemond? He is a prince with one eye, disinherited, dragonless, hated by his own blood, holding nothing but a name and the rare ability to bond with a dragon. He is the loneliest man in Westeros right now, and he has just found the loneliest woman. I think these two deserve each other, and they will make a great pair.

The gaps in Fire and Blood have people theorising that Alys is linked to Brynden Rivers

What follows leans on Fire and Blood and on where I think this is heading. The show has already rewritten her origin once, so none of it is guaranteed. If you want to stay clean of spoilers, stop here.

After Aemond dies at the Gods Eye, Alys is said to be carrying his child. In 131 AC she is holding Harrenhal, calling herself Aemond's widow, putting forward a boy she says is his lawful heir and the true king, and refusing to submit when knights arrive to demand it. She is said to have had a dragon, and that is where the book stops. That is the problem with the book: it gives you half the story and leaves you to figure out the rest.

One figure people theorise about is Brynden Rivers, the Bloodraven. He was a greenseer who saw across time and space, an albino so pale he looked like something that had never been in the sun. He lost an eye to a kinsman and carried Dark Sister, the sword Daemon carries right now. Half the realm called him a sorcerer, whispering that he had a thousand eyes and one. Aemond will one day say of Alys that she sees much and more, the same thing said about Brynden.

They share the surname, but as I said above, Rivers is a name given to bastards of the Riverlands. Brynden's mother was Melissa Blackwood of Raventree Hall, mistress of Aegon the Fourth, and he was born in 175 AC. Alys's son was born around 131, more than 40 years earlier, so we cannot say Alys gave birth to him. But the Blackwoods are a Riverlands house that kept the old gods when the rest of the south turned to the Seven, and they still keep a dead weirwood in their courtyard. A boy raised at Harrenhal by the woman who bargained with the Isle of Faces, a few generations of Riverlands marriages, and a Blackwood girl who catches a king's eye: that needs four generations and no sorcery, and it still puts Alys's blood behind the eyes of the three-eyed raven.

Brynden's fate mirrors the price Alys paid

Look at how Brynden ends. He reaches for more than a man is meant to have and pays by being fixed to a single place forever, roots growing through him, unable to die and unable to leave, until another boy takes the weight off him. Whether Alys is his mother, his ancestor four times removed or no relation at all, House of the Dragon and Game of Thrones have drawn a similarity in the cost of treating with the unknown.

Is the show's version canon? Not at all. Nothing on screen binds what George writes, but nothing in it contradicts Fire and Blood either. I personally give it credit for filling a hole the books leave open. The maesters she sent for failed her, and that turned her into the woman they now call a witch.

Do you believe Alys is telling Aemond the truth about who she is, or is it a story spun to win him over?
