Cortana: Symbol of Lost Heroism and Renewed Identity in Chain of Iron

What Is Cortana?

Cortana is a legendary Shadowhunter sword forged by Wayland the Smith, one of three sibling blades along with Joyeuse and Durendal. It has been passed down for generations in the Carstairs family. In Chain of Iron, Cordelia Carstairs bears Cortana as her primary weapon, and the sword is deeply tied to her sense of self‑worth and her aspiration to be a great hero. The hilt bears words declaring it to be of the same steel and temper as its famous siblings.

The sword appears physically in many scenes, but its symbolic weight shifts dramatically across the novel. It begins as an emblem of Cordelia’s heroic lineage and her belief that she can live up to the legends of her ancestors, and evolves into a test of her identity, her agency, and her trust in herself.

Where Cortana Recurs

Cortana’s presence is felt throughout the story, but key turning points include:

  • Chapter 10 – After Cordelia stabs Belial with Cortana, the sword later burns her palm during a fight with an Ourobas demon. She drops it and has to retrieve it warily, sensing rejection.
  • Chapter 11 – Cordelia confirms the sword has gone silent; it no longer “speaks” to her in the way it used to. She feels a wrongness, a loss of the familiar communion.
  • Chapter 14 – Cordelia travels to the Uffington White Horse to seek Wayland the Smith. He heals Cortana and asks her to swear an oath of fealty, making her a paladin.
  • Chapter 20 – After the paladin oath, Cordelia fights Hauras and Naga demons with increased power; the blade burns with bronze‑gold energy and demons flee from her.
  • Chapter 22 – James is pulled back from Edom partly by Cordelia’s call wielding Cortana, and Belial still bears an unhealed wound from the sword.
  • Chapter 25 – Lilith reveals she was Wayland the Smith all along; the oath was sworn to her, not to a benevolent smith. Cortana now binds Cordelia to the Queen of Demons.
  • Chapter 26 – Cordelia confesses to her friends that she is Lilith’s paladin.

How Cortana’s Meaning Changes

1. Emblem of Heroic Identity

Initially, Cortana represents everything Cordelia wants to be: a renowned warrior like the heroes of legend. The sword “chose” her, and she believes that bearing it proves she is worthy of the Carstairs name. It is a symbol of honor, courage, and destiny.

2. Rejection and Self‑Doubt

After Cortana touches Belial’s blood, the sword burns Cordelia and falls silent. The rejection triggers a crisis of identity: “I am not worthy of it anymore” (Chapter 12). The weapon that once validated her heroic self is now a source of shame. Her worth feels stripped away.

3. False Renewal as a Paladin

Cordelia’s pilgrimage to Wayland the Smith appears to restore Cortana and even elevate her power. Swearing fealty makes her a paladin, and she feels triumphant. The renewed Cortana seems to confirm she can be a hero again. But this renewal is a trap: the “Wayland” figure is Lilith in disguise.

4. The Horrifying Truth of Enslavement

When Lilith reveals the deception, Cortana becomes a chain binding Cordelia to a demon prince. The sword that once gave her agency now robs her of it. She is forced to fight Belial against her will, her body moving on its own. The symbol of heroic freedom transforms into a symbol of manipulation and loss of control.

Character Connections

  • Cordelia Carstairs (/books/chain-of-iron/characters/cordelia-carstairs/): Cortana is her external identity. Her arc from confident bearer to doubting wielder to involuntary paladin mirrors her struggle with self‑worth and the cost of seeking power.
  • James Herondale (/books/chain-of-iron/characters/james-herondale/): James supports Cordelia’s quest, witnesses her bond with Cortana, and later fights alongside her. He seen her as “Achilles come to South London” after her paladin empowerment.
  • Lilith (as Wayland the Smith): The false Wayland represents the corrupting use of symbols. She uses Cortana to trick Cordelia into an oath of fealty, exploiting Cordelia’s desire for heroism.
  • Belial: Cortana wounds Belial, and he still bears the scar. The sword is a threat to him, and he cannot harm Lilith’s paladin directly, so he attempts to bargain instead.
  • Alastair Carstairs (/books/chain-of-iron/characters/alastair-carstairs/): He refuses to take Cortana from Cordelia and suggests she seek the Silent Brothers, showing his faith that the sword hasn’t rejected her.

Theme Connections

Cortana weaves through several of the novel’s core themes:

  • Identity and Self‑Worth (/books/chain-of-iron/themes/identity-and-self-worth/): Cortana’s silence forces Cordelia to question whether her value comes from the sword or from within.
  • Secrecy and Deception (/books/chain-of-iron/themes/secrecy-and-deception/): The entire paladin oath is built on a lie. Cordelia keeps the oath secret until she must confess it.
  • Power and Control (/books/chain-of-iron/themes/power-and-control/): Lilith gains power over Cordelia through the sword. Cortana becomes a tool of control rather than empowerment.
  • Love and Illusion (/books/chain-of-iron/themes/love-and-illusion/): Cordelia’s love for James and her desire to be a hero both lead her to believe in a false Wayland. The illusion of a noble oath masks a demonic bargain.
  • Sacrifice and Redemption (/books/chain-of-iron/themes/sacrifice-and-redemption/): The sword ultimately demands sacrifice of Cordelia’s freedom. Her redemption may require breaking the paladin bond in the next book.

Four Study Questions

Question 1

In Chapter 10, Cordelia drops Cortana when it burns her. What does this moment reveal about the relationship between a Shadowhunter and their weapon?

Answer: The burning shows that a weapon forged in heavenly fire can be corrupted by contact with demonic essence (Belial’s blood). It also reveals that the bond is not permanent; the sword can “reject” its bearer, undermining Cordelia’s sense of being chosen. The physical pain mirrors her emotional shock at losing her heroic identity.

Question 2

Why does Cordelia swear an oath to Wayland the Smith, and how does the text later undercut this choice?

Answer: She swears fealty because she believes it will restore Cortana and make her a more powerful warrior. The text undercuts this when Lilith reveals she was Wayland all along. Cordelia’s desire to be a hero is exploited; the oath binds her to a Prince of Hell. The noble act becomes a trap.

Question 3

Compare the way Cortana is described before and after the paladin oath. What does the change in its behaviour suggest about the nature of power in the novel?

Answer: Before the oath, Cortana is silent and feels wrong. After the oath, it burns with bronze-gold light and gives Cordelia superhuman strength. The change suggests that power often comes with hidden strings. The oath amplifies her abilities but at the cost of her autonomy—power in this novel is rarely free.

Question 4

In Chapter 25, Lilith says: “You are mine. … I choreographed each decision you made.” How does Cortana serve as a symbol of Cordelia’s lost agency?

Answer: Cortana is the tool through which Lilith manipulates Cordelia. From the initial burning (which Lilith caused) to the forged healing and oath, every step was engineered. The sword goes from being a symbol of Cordelia’s choice to a symbol of her imprisonment. She can no longer lift it in her own name; she does so in Lilith’s.
