Summary

Cordelia enters Westminster Abbey to face Belial, who inhabits James’s body. She uses Cortana to demonstrate its healing power and pleads for James to return. James briefly regains control, asks for Cortana, and stabs himself, believing this is the only way to kill Belial. Belial emerges from James’s body and is destroyed by a spear of light from Heaven. Meanwhile, at the abbey, Lucie uses her necromantic power to compel the souls of possessed Iron Sisters and Silent Brothers to expel the Chimera demons, ending the battle. James survives the wound, and Cordelia heals him with Cortana. Lilith appears to reclaim Cordelia as her paladin, but Cordelia reveals her vow was cleverly worded: Belial died by Cortana, not by Cordelia’s hand, so the oath is fulfilled and Lilith has no power over her. James threatens Lilith, who flees. The chapter ends as family and friends flood the cathedral, and James tells Cordelia that she believed in him.

Character Development

  • James Herondale – Sacrifices himself willingly to destroy Belial, trusting Cordelia to act at the right moment. He survives and is reunited with Cordelia, showing his faith in her is rewarded.
  • Belial – Reveals a vulnerability to emotion and fear; his final moment shows a lost angel longing for Heaven.

Themes, Symbols, or Motifs

  • Faith and Belief – Cordelia’s belief in James is the catalyst for his temporary control; James tells her she believed in him. Belief acts as a counterforce to Belial’s will.
  • Sacrifice and Resurrection – James’s self-stabbing is a Christ-like sacrifice; his healing by Cortana represents a form of resurrection.
  • The Power of Words – Cordelia’s careful phrasing of her vow to Lilith (that Belial would die “by my blade,” not by her hand) frees her from the paladin bond.
  • Light vs. Darkness – Divine light descends to destroy Belial; sunlight floods the abbey after his death, symbolizing restoration.
  • Cortana as a Dual Symbol – The sword represents both justice (wounding) and love (healing), as Cordelia states.

Why This Chapter Matters

This chapter resolves the central conflict of the novel: Belial’s possession of James and his plan to take over London. James’s sacrifice and Cordelia’s faith prove more powerful than a Prince of Hell, affirming that love and free will can overcome demonic control. The chapter also completes Cordelia’s arc from reluctant paladin to a hero who uses her power on her own terms, and it frees her from Lilith. The mass reunion of characters marks the beginning of the story’s denouement.

Study Questions and Answers

  1. How does Cordelia use the exact wording of her vow to escape Lilith’s control?
    Cordelia asked Lilith to swear that if Belial died by her blade (Cortana), she would be freed. Belial died by James’s hand using Cortana, not by Cordelia’s own hand, fulfilling the letter of the vow without Cordelia having to strike the blow.

  2. Why does James ask for Cortana and then stab himself?
    James believes that killing himself while Belial is in his body is the only way to destroy Belial. He trusts Cordelia to know the right moment to give him the sword, and he proves willing to sacrifice everything to save London.

  3. What role does Lucie’s necromancy play in the battle at the abbey?
    Lucie reaches out to the souls of the possessed Iron Sisters and Silent Brothers, compelling them to expel the Chimera demons from their bodies, which ends the Watcher threat and allows the Shadowhunters to defeat the demons.
