The Iron Keys in Ruthless Vows: Symbols of Access, Agency, and Choice

What the Iron Keys Are

In Ruthless Vows, the iron keys are five physical objects forged by the god Dacre in the hottest fire of his realm. As he explains to Roman Kitt in chapter 15, Dacre forged them after learning a hard lesson about vulnerability, vowing to make it harder for anyone who might seek to harm him or his family. Each key can unlock thresholds—doorways that connect the mortal world to the under realm, Dacre's domain of ley lines, buried cities, and magical passages.

The keys are not ordinary metal. When brought near a door, they cause a keyhole to appear where none existed before. In chapter 15, Dacre demonstrates this by slipping his key into a wardrobe's brass handle, transforming an ordinary closet into an entrance to a stone staircase descending into the under realm. The doorways themselves have preferences: Dacre notes that his thresholds like to be close to fire and stone, swallowing up ashes, embers, and the unseen magic of a hearth. This detail ties the keys to the elemental and domestic—the hearth as a site of both warmth and hidden passage.

The Sacred Number Five

Dacre's choice to forge exactly five keys is deliberate and rooted in the numerology of his world. He tells Roman that five is a sacred number: five days of the week, five boroughs, five chancellors, five remaining divines. For the gods, he says, five is both a blessing and a warning. His reasoning is striking: "Having four confidants is one too few, and six is one too many." The keys are thus not merely tools of access but instruments of trust—a physical measure of how many people Dacre believes he can rely on. The number five encodes a philosophy of cautious, limited intimacy, one that assumes betrayal is always possible and that trust must be rationed.

This framing makes the keys inseparable from the novel's exploration of loyalty and deception. Dacre's trust is conditional and transactional, and the keys are its currency. Whoever carries a key carries a piece of Dacre's confidence—and, by extension, a piece of his power.

Where the Keys Recur

The keys appear at several pivotal moments, each time carrying slightly different weight.

Dacre's own key hangs around his neck on a chain, alongside a small silver flute. Roman notices the clinking sound these objects make when Dacre walks. The key is part of Dacre's identity as a divine being—an emblem of his dominion over the under realm and his ability to move between worlds at will.

Val's key is revealed in chapter 18, when Roman deduces that Val, one of Dacre's favored advisors, must also possess one of the five keys. Val uses the underground routes to deliver Roman's articles to the Oath Gazette, and his key grants access to the one active doorway in Oath—the threshold at the Kitt estate. This key represents the enemy's reach into the mortal world, the quiet infiltration of Dacre's influence into the heart of the city.

Captain Landis's key appears in chapter 42 as a bloodstained iron key on a chain, lying on a table after the captain's death. Roman studies it from an arm's length away, recognizing "the power to unlock thresholds, just beyond his reach." This moment crystallizes Roman's position: he is surrounded by power he cannot claim, trusted enough to witness but not enough to wield.

Iris's key is taken from Val's body in chapter 48. After Iris kills Val in self-defense, his chains break, and a flute and an iron key clink to the floor. Despite her brother's protests, Iris takes both. This is the key's most significant transformation: it passes from a servant of Dacre to a woman determined to oppose him. Iris later uses it in chapter 50 to unlock a door in Gould's café, descending into the under realm with Attie and locking the threshold behind them—a deliberate act of sealing off one realm from another.

Enva's key appears in the epilogue. Iris left her key on Enva's cathedral altar, and Enva now wears it around her neck. Touching it, she reflects that she could reopen the under realm, which sleeps since Dacre's death. Bound by a bargain with Alzane that keeps her captive to Oath, Enva wonders if going below could let her travel in flesh. She unlocks a lavatory door, retrieves her harp from a charmed pocket, and descends into the under realm, vanishing.

How the Meaning Shifts

The keys begin as instruments of divine control. Dacre forges them to protect himself and his family, to limit who can access his realm. They are symbols of his authority and his paranoia—a way of keeping the world at a distance while still moving through it. The keys are also instruments of war: Dacre uses the under realm's routes to move his forces, and the keys are the means by which his soldiers and advisors cross between worlds.

As the novel progresses, the keys become symbols of agency and choice. When Iris takes Val's key, she seizes a measure of Dacre's power for herself. The key allows her to choose her own path into the under realm, to confront the god on his own territory. Her decision to lock the door behind her and Attie is an act of deliberate separation—she controls who follows and who does not.

By the epilogue, the key has become a gift and a release. Iris leaves it on Enva's altar, transferring the power of access to the goddess who helped her. For Enva, the key represents freedom from her captivity in Oath—a way to finally leave the city that has become her prison. The key that Dacre forged to protect himself becomes the means by which his former lover escapes her bonds.

Character Connections

The keys illuminate each character's relationship to power and trust.

Roman Kitt is the perpetual observer of the keys. He watches Dacre use his, deduces Val's possession of one, and studies Captain Landis's bloodstained key with longing and frustration. The keys are always just beyond his reach, mirroring his larger position in Dacre's court: trusted enough to be useful, never trusted enough to be empowered. Roman's relationship to the keys is one of knowledge without agency—he understands their power but cannot claim it.

Iris Winnow is the key's true inheritor. She takes it through violence and necessity, and she uses it to make her own choices: to enter the under realm, to lock the door behind her, and ultimately to give the key away. For Iris, the key is a tool of resistance, a way of turning Dacre's own magic against his plans.

Dacre is the forger and the original holder of the keys. They embody his desire for control and his fear of betrayal. The keys are his answer to vulnerability—a way of ensuring that only the chosen few can reach him or his realm.

Enva receives the key as a gift and uses it to reclaim her freedom. Her story arc—from captive in a gilded cage below, to goddess bound in Oath, to traveler descending into the under realm—is completed by the key's transfer. The key that once symbolized Dacre's hold over her becomes the instrument of her release.

Theme Connections

The iron keys resonate with several of the novel's central themes. They are physical manifestations of access and agency—who gets to move between worlds, who gets to choose their path. They also speak to trust and betrayal, since Dacre's entire system of keys is built on the assumption that trust must be limited and guarded. The keys connect to the theme of war and grief through their role in Dacre's military campaign, and to love and sacrifice through Iris's gift to Enva. Finally, the keys' connection to the under realm ties them to the novel's exploration of memory and identity—the under realm is a place of buried histories and forgotten routes, and the keys are the means of accessing what has been hidden.

Study Questions

1. Why does Dacre forge exactly five keys, and what does this reveal about his philosophy of trust?

Dacre forges five keys because five is a sacred number in his cosmology—five days of the week, five boroughs, five chancellors, five remaining divines. His explanation that "having four confidants is one too few, and six is one too many" reveals a worldview in which trust is a scarce resource to be rationed. The keys are not just tools; they are a physical limit on intimacy, a way of ensuring that Dacre never again finds himself vulnerable to betrayal. This philosophy ultimately proves self-defeating, as the keys pass into the hands of those who oppose him.

2. How does the meaning of the key change when it passes from Val to Iris?

Under Val, the key is an instrument of Dacre's will—a means of delivering articles, moving through the under realm, and infiltrating Oath. When Iris takes it from Val's body, the key becomes a tool of resistance. She uses it to enter the under realm on her own terms, to lock the threshold behind her, and eventually to give it to Enva as a gift of freedom. The key's meaning shifts from control to agency, from serving a god's war to enabling a mortal's choice.

3. What does Roman's observation of Captain Landis's bloodstained key reveal about his position?

When Roman sees the bloodstained key on the table, he recognizes "the power to unlock thresholds, just beyond his reach." The image captures his entire situation: he is close to power, trusted enough to witness it, but never permitted to wield it. The blood on the key also reminds him of the cost of Dacre's war—the key is stained with the death of a captain, a reminder that access to the under realm comes at a price.

4. Why does Iris leave her key on Enva's altar, and what does Enva's use of it signify?

Iris leaves the key on Enva's altar as a gift, transferring the power of access to the goddess who aided her. For Enva, bound by her bargain with Alzane to remain in Oath, the key offers a way out—a chance to travel in flesh by descending into the under realm. Her use of the key in the epilogue completes the symbol's arc: the key Dacre forged to protect himself becomes the means by which his former lover escapes her captivity. The key that began as an instrument of control ends as an instrument of liberation.
