Who Is Nona in Nona the Ninth? Harrow, Alecto, Gideon and the Ending Explained

Editorial image generated by the author.

Tamsyn Muir begins Nona the Ninth with a problem that sounds simple enough: a young woman has woken up in somebody else's body and does not remember who she is.

Unfortunately, this is The Locked Tomb.

The body belongs to Harrowhark Nonagesimus. Harrow's body has previously contained Gideon Nav's soul. Harrow herself vanished somewhere during the ending of Harrow the Ninth. Gideon's corpse still exists elsewhere. And the woman in the Locked Tomb—the figure Harrow has seen and worshipped since childhood—has her own unexplained connection to everything that happened. Camilla, Palamedes and Pyrrha therefore spend months trying to determine whether the cheerful amnesiac calling herself Nona is Harrow, Gideon or something else entirely.

The answer is that Nona is the amnesiac Alecto-presence inhabiting Harrow's body. Without Alecto's remembered identity, that presence spends roughly six months developing into the personality we know as Nona.

That solves the body-swap mystery. It does not completely answer the more interesting question, because Nona does not experience herself as Alecto. She loves different people, wants different things and has built a life she desperately wants to keep. By the time Alecto's identity begins returning, Nona does not experience that as becoming whole. She experiences it as disappearing.

That is the real problem at the centre of Nona the Ninth. The novel begins by asking whose soul is inside Harrow's body? It ends by asking whether knowing where that identity came from is enough to tell us who the person is.

Major spoilers for Gideon the Ninth, Harrow the Ninth and Nona the Ninth follow.

Why Nona Could Be Harrow, Gideon—or Someone Else

The easiest way to understand Nona's identity problem is to begin with the mess left behind by Harrow the Ninth. At the end of Gideon the Ninth, Gideon sacrifices herself and Harrow absorbs enough of her soul to become a Lyctor. Harrow then deliberately damages her own ability to recognise Gideon in an attempt to prevent Gideon from being completely consumed.

That works. Gideon remains hidden within Harrow and eventually takes control of Harrow's body. Harrow's own consciousness withdraws instead of returning to a body Gideon is occupying, while Pyrrha Dve—herself the surviving cavalier identity inside Gideon the First's body—escapes with Harrow's body after the disaster at the Mithraeum.

Six months later, Nona the Ninth opens with that same body, but Gideon is no longer the person controlling it. Nona is.

Camilla, Palamedes and Pyrrha therefore have a genuine diagnostic problem. They know the body is Harrow's. They know Gideon survived inside Harrow. They know Harrow herself is missing. They also know that bodies, souls, memories and personalities no longer line up in any simple way. Harrow has already rewritten her own mind, Palamedes can survive inside Camilla, and Pyrrha endured for millennia inside Gideon the First.

Nona could plausibly be Harrow without her memories. She could plausibly be Gideon without hers. Instead, the evidence gradually points toward a third possibility.

Nona is terrible at necromancy despite inhabiting Harrow's extraordinarily powerful body. She has neither Harrow's temperament nor Gideon's recognisable mix of anger, humour and obsession. She is unusually affectionate, fascinated by faces and bodies, and able to understand people with a speed neither Harrow nor Gideon possesses. Most revealingly, she can communicate with Varun, the Resurrection Beast threatening the planet.

Resurrection Beasts are the revenant souls of murdered planets. If the person inside Harrow can hear one—and be recognised by it—then perhaps looking for another human necromancer or cavalier is the wrong category entirely. The answer has been sitting in the Locked Tomb since before the series began.

Nona Is Alecto—but What Is Alecto?

Alecto is the woman imprisoned in the Locked Tomb: the figure Harrow encountered as a child and has loved, worshipped and hallucinated ever since. But Alecto was not originally an ordinary human woman.

The John chapters in Nona the Ninth reveal the broad outline. Before John Gaius became the Emperor Undying, he was a scientist on Earth during a worsening climate catastrophe. His work on cryogenic preservation became entangled with escalating political conflict, and during that crisis John discovered an ability to manipulate death itself.

His power expanded until the struggle around Earth's future became catastrophic. John killed billions and ultimately extended the destruction far beyond Earth. In the process he reached for the soul of the dying planet itself, consumed part of it and discovered that he could not contain the whole.

John then fashioned a human-shaped body from his own flesh and bone to hold what he could not absorb. That being became Alecto.

This origin is why Alecto never fits comfortably into the categories used for everyone else. She is not simply an unusually powerful necromancer, an ordinary revenant or a cavalier in precisely the same sense that Gideon was Harrow's. At the root of her identity is something planetary.

Once that is understood, Nona's strangest abilities make more sense. Her relationship to language, bodies and Resurrection Beasts is not evidence that Harrow has suddenly developed new talents. It is evidence that whoever is using Harrow's body is something very different from Harrow.

Nona's linguistic ability is one of the strongest clues. She has not consciously learned every language around her and cannot necessarily read them, yet linguistic difference often seems almost transparent to her. The novel never gives this a technical explanation, so the connection to her planetary identity remains interpretation rather than a stated rule. Her ability to understand Varun, however, pushes the same clue much further: the thing listening to a planetary revenant is itself connected to a planetary soul.

She may have forgotten being Earth.

Earth has not entirely forgotten how to hear.

Where Is Harrow, and What Are the John Chapters?

While Nona lives in Harrow's body, Harrow has not simply ceased to exist. This is one of the places where Nona the Ninth deliberately resists a neat body-and-soul diagram.

Throughout the novel, Nona sleeps or loses consciousness and the narrative shifts into the strange John chapters. John recounts the destruction of Earth to someone who appears to be Harrow, yet the memories and history he describes are bound up with Alecto's past.

The scenes therefore operate on several levels at once: John's recollection of the old world, Alecto's buried history and Harrow's experience of that history. Harrow somehow occupies the place in these memories once associated with Alecto, just as Nona occupies the body associated with Harrow.

The exact metaphysical location of Harrow during this process is not explained cleanly. The ending of Harrow the Ninth placed her in an interior version of the Locked Tomb; Nona continues to connect her displaced consciousness with Alecto, the Tomb and the River without reducing that arrangement to a simple statement that Harrow is literally "inside" one particular body.

For following the story, the symmetry matters more than the precise metaphysical map. Nona has Harrow's body without Harrow's autobiographical identity. Harrow receives a past connected to Alecto while Nona lives without access to that past.

This is why the John chapters belong inside Nona the Ninth rather than functioning merely as a detached prequel. Nona is living the present without Alecto's remembered history, while Harrow is encountering the history Nona does not know.

Those chapters also strip away the mythology surrounding John's Resurrection. The Houses remember him as the god who brought humanity back from death. His own account reveals a much darker prehistory: he did try to save Earth, but his response to failure became inseparable from anger, control and catastrophic violence. The Resurrection follows an apocalypse in which John himself played a decisive role.

Alecto is uncomfortable evidence of that buried history. She is Earth made personal, and John's power cannot be separated cleanly from the destruction that produced her.

The fuller story of John, Earth and the Resurrection deserves its own explainer. For Nona's identity, one fact is enough: the cheerful young woman living an ordinary six-month life in Harrow's body originates in something as old and vast as the world humanity lost.

What Happened to Gideon—and Who Is Kiriona Gaia?

Gideon returns during Nona the Ninth, but not as the Gideon who died at Canaan House.

She now calls herself Kiriona Gaia, Prince of the Empire and daughter of John Gaius. She inhabits Gideon's preserved original corpse, altered into an extraordinarily durable construct. Whatever exactly John has done, the person animating that body is recognisably Gideon.

How complete that restoration is remains deliberately uncertain, which matters because the obvious temptation is to say that Gideon has simply been resurrected. The Locked Tomb has spent three books making simple identity equations increasingly unreliable.

Gideon's soul was partially incorporated into Harrow. Enough survived to narrate much of Harrow the Ninth and eventually control Harrow's body. Some version or portion of Gideon has now been restored to Gideon's corpse, but Kiriona has also died, spent months entangled with Harrow, discovered John is her father and acquired a new title, political role and relationship to the Empire.

She is unmistakably Gideon, but she is not Gideon returned untouched to the moment before her death.

The name Kiriona Gaia therefore does more than sound grandiose. John has attempted to place Gideon inside his own story. She is no longer merely Gideon Nav, unwanted child of the Ninth House. She is the Emperor's daughter and heir.

That does not mean Gideon has ceased to be Gideon. It means that, like almost everyone in Nona the Ninth, she now carries more than one identity at once.

Paul and the Problem of Becoming Someone New

Camilla and Palamedes provide the novel's clearest comparison with Nona. Palamedes has been surviving inside Camilla, and the two share one body while remaining recognisably distinct people. Their arrangement cannot continue indefinitely, so they choose something more radical.

They become Paul.

Paul is not merely Palamedes controlling Camilla permanently, nor Camilla with Palamedes's memories added. The resulting person is presented as someone new, produced from both. Camilla and Palamedes continue into Paul in some sense, but they no longer exist as separate individuals, and their friends grieve them even while Paul stands in front of them.

The comparison with Nona is not exact, but it exposes the weakness in treating identity as an inventory of metaphysical ingredients. We can say that Paul comes from Camilla and Palamedes without reducing Paul to either one. Likewise, we can say that Nona comes from Alecto and lives in Harrow's body without proving that Nona's six months were merely an error waiting to be corrected.

Nona's amnesia therefore becomes more than a plot device. Losing access to an earlier identity does not freeze personal development. During six months without Alecto's remembered past, Nona develops fears, routines and loyalties of her own. She loves Camilla, Palamedes and Pyrrha. She loves the children at school and Noodle. She experiences the world through Harrow's body without thinking of herself as Harrow, and carries Alecto's underlying identity without experiencing herself as Alecto.

She experiences herself as Nona.

That makes the return of Alecto more troubling than ordinary memory recovery. If someone regains a forgotten past, we normally describe the change as restoration. For Nona, the returning identity is so ancient and so different from her present personality that restoration begins to resemble replacement.

Nona is frightened of remembering because she senses that the return of whoever she used to be may mean the end of whoever she is now. Saying "Nona is Alecto" therefore solves the mystery without resolving the emotional problem. It tells us where Nona came from. It does not tell us that Nona was never real.

Why Nona Is Dying and What Happens at the Tomb

As the novel approaches its ending, Nona begins to deteriorate. Palamedes diagnoses the problem as a soul becoming untethered from the wrong body: whatever extraordinary healing Harrow's body can perform, the arrangement itself cannot continue indefinitely.

At the same time, Varun draws closer, the political situation on New Rho collapses, Blood of Eden and the Cohort converge, and the survivors become increasingly desperate to reach the Ninth House. Nona herself feels an ever stronger pull toward the Locked Tomb, another sign that Alecto's submerged identity is reasserting itself and orienting toward Alecto's body.

By this point Nona increasingly understands what reaching the Tomb may mean. It may restore Harrow. It may restore Alecto. But Nona has no reason to assume that the personality she has become will survive the transition as a separate self.

Everyone else needs Nona to become someone else.

Nona wants to stay Nona.

The survivors eventually reach the Ninth House and enter the Locked Tomb. Inside lies Alecto's body, preserved behind John's blood ward and the elaborate protections surrounding the Tomb.

When Nona reaches it, the unstable arrangement resolves. Alecto returns to Alecto's body and Harrow awakens again in Harrow's. Whatever the precise soul mechanics involved in reaching that point, the practical outcome is clear: the central identities have returned to the bodies with which the series originally associated them.

Alecto awakens as someone strikingly unlike the girl we have followed. Her perspective is ancient, strange and alien. She recognises Harrow not through Nona's six months of friendship and domestic life but through older categories, especially Harrow's connection to Anastasia.

Alecto remembers her ancient vow to Anastasia and recognises Harrow as belonging to Anastasia's line. Harrow, who has worshipped the Body since childhood, finally encounters the awakened being around whom she built so much of her identity.

The reunion is not remotely what Harrow imagined.

Alecto then goes to John and stabs him through the chest. John wakes and greets her.

The story that began before the Resurrection has resumed.

Did Nona Die?

Mechanically, it is tempting to say no. Nona is Alecto; Alecto survives; therefore Nona survives. But the novel spends hundreds of pages making that answer increasingly unsatisfactory.

Paul provides the clearest comparison. Camilla and Palamedes continue in some sense within the person they create, yet nobody treats their loss of separate existence as meaningless. Paul's survival does not make grief irrational.

Nona presents almost the inverse problem. An ancient identity temporarily loses nearly everything that made it recognisably itself. Without Alecto's remembered purposes, history and relationships, a new personality develops in their place.

When Alecto returns, Nona is no longer separately present in the form we knew. Whether that should be called death, integration, transformation or the end of a temporary self is exactly the question the novel leaves emotionally unresolved. What matters is that Nona herself wanted a future as Nona: she formed relationships, remembered experiences, made choices and feared the return of the identity that preceded her.

This is where Muir's own description of the novel in terms of rebirth rather than simple resurrection becomes especially useful. Resurrection, as Muir describes it, allows someone to pick up what they had before; rebirth opens the possibility of choosing something new.

Nona the Ninth contains several versions of that problem. Gideon dies and returns as Kiriona Gaia. Camilla and Palamedes surrender their separate identities and become Paul. Alecto loses access to herself and becomes Nona. Harrow disappears into someone else's history and eventually returns to her own body. None of these transformations leaves identity untouched.

That is also why Nona works so well as the inverse of Harrow the Ninth. Harrow is built around deliberate absence: Harrow removes Gideon from her own memory because forgetting her is the only way she can imagine preserving her. Nona reverses the experiment. Alecto loses access to herself, and in the space left by that absence another personality develops.

For most of the novel, the reader asks the same question as Camilla and Palamedes: Who was Nona before she lost her memory?

The answer is Alecto.

By the time we receive it, however, the more important question has changed: Who did she become while she could not remember?

That answer is Nona.

"Nona is Alecto" tells us where the identity came from. It does not make Nona's loves, fears, friendships and six months of consciousness unreal.

Nona the Ninth begins as a puzzle about which soul is occupying the wrong body. By the end, the bodies and souls can be labelled more clearly again: Harrow is awake in Harrow's body, Kiriona occupies Gideon's, and Alecto has returned to her own.

The metaphysics have become clearer.

The personhood has not.

"Who is Nona?" has a simple metaphysical answer. The tragedy of the novel is that it does not have a simple personal one.
