Will burns the remaining dark artefacts, trying to reject the legacy tied to his former life.
The group sets its sights on Italy, believing an ancient gate in the Hall can lead them to Umbria, where they hope to find Ettore Fasciale—someone who might know how to stop Sinclair, the powerful enemy who threatens the world once more.
Meanwhile, a new and strange development unfolds: the body of Katherine, once a Light Champion, has been reanimated—inhabited by Visander, another champion from the past.

Characters
Will (Sarcean, the Dark King Reborn)
Will stands at the heart of Dark Heir, a tragic figure torn between a dark legacy and a stubborn resolve to forge a different future. As the reincarnation of Sarcean—the feared Dark King—Will is burdened with power and memory, but not certainty.
From the opening chapters, his internal battle is evident. He hides his identity, destroys dark relics, and seeks redemption even before asking forgiveness.
His relationship with James is pivotal; James represents both his past failure and his hope for loyalty. Will’s eventual confession of his identity is a shattering moment, as he risks the fragile trust holding the group together.
Yet, through every betrayal and revelation, Will moves with growing clarity toward light. This culminates in his decision to sacrifice part of himself to reseal the Fifth Seal.
His arc is one of deliberate rejection of destiny. He may have been born into darkness, but he chooses against it, again and again.
James (Anharion Reborn)
James is perhaps the most hauntingly complex figure in the novel. He is a man wrestling with the shadow of who he was—Anharion, the noble Steward turned enslaved champion of the Dark King.
His journey is a descent into memory and a struggle for autonomy. At first, James is uncertain, fractured between his present self and the echoes of Anharion.
His loyalty to Will is intimate and consuming, born of both history and current emotion. The memories of being collared and forced to kill the Lady return gradually, fueling guilt and doubt.
But unlike a man trapped in the past, James ultimately emerges with agency. He chooses Will, not because magic commands him, but because love and conviction do.
In the climactic battle, he rejects Sinclair’s relics and the legacy of darkness. He fights as a free man.
James is the character who most clearly illustrates that identity is not fate. It is choice.
Violet
Violet is the moral compass and realist of the group. She is a survivor who bears her own losses but continues to fight for what she believes is right.
Her arc begins with mistrust—of James, of Will’s secrecy, of the haunted history surrounding them. Yet her strength lies in discernment and restraint.
She refuses to act rashly even when suspicion rises. Violet chooses instead to watch, to ask, and ultimately to confront.
Her loyalty is not blind. She tests those around her, holding them accountable even as she stands beside them.
When Will’s truth is finally revealed, she does not abandon him outright. But neither does she condone his silence.
Violet is the lens through which the reader gauges moral clarity. Wounded but unyielding, she survives the final battle with her beliefs intact and her loyalty tested but not broken.
She is not simply a warrior. She is conscience in motion.
Cyprian
Cyprian is a volatile mix of grief, loyalty, and fire. From the start, he is a foil to both James and Will—suspicious of their histories, defiant against authority, and fiercely devoted to Violet.
His grief over the fall of the Stewards and the loss of their moral world never dissipates. It shapes his distrust of the reborn figures around him.
Yet Cyprian is not blind in his hatred. His loyalty to Violet anchors him.
He is willing to stand against Will even when it means personal risk. Throughout the book, Cyprian remains a symbol of the old order: proud, principled, but perhaps too rigid to grasp the nuance of rebirth and redemption.
In the end, he survives not as a reconciled friend, but as a wary ally. He is someone who will always question, always guard, but may one day understand.
Visander (in Katherine’s Body)
Visander is a wild card—an ancient Champion of the Light, resurrected in the most disorienting way possible: within the body of the recently dead Katherine. From the moment of his reawakening, Visander’s story is one of identity crisis, manipulation, and ultimately transformation.
Initially cold and calculating, Visander hides behind Katherine’s face while plotting to strike at the Dark King once more. But as the novel progresses, he begins to see nuance in Will.
He recognizes restraint and sorrow in the young man thought to be Sarcean. Visander’s arc bends toward comprehension—he does not forgive, but he does understand.
In the end, it is this understanding that saves Will’s life. Visander chooses not to kill him after seeing the sacrifice he made to seal the Fifth Seal.
Visander embodies the complicated memory of war. He is idealistic, brutal, but capable of learning.
Sinclair
Sinclair is the shadow behind the rising dark. He is an antagonist who represents control, legacy, and power unchecked.
He is less a man than a force—manipulating relics, hunting ancient powers, and amassing armies. Sinclair is a believer in destiny and bloodline, using Katherine’s body, James’s past, and the Dark King’s memory as tools in a larger campaign of resurrection and conquest.
He is relentless, and though he suffers defeat at the end, he is not gone—only wounded. As a character, Sinclair lacks the emotional range of Will or James.
But he serves an essential role. He is the embodiment of what happens when the past is wielded as a weapon rather than a lesson.
Ettore Fasciale
Ettore is the enigmatic scholar and guide whose riddles and warnings shape the group’s path in Umbria. While he may not dominate the page, his presence is vital.
He is one of the few who understands the ancient magic, the seals, and the consequences of Will’s bloodline. His fear of Undachar and his attempts to keep it sealed speak to the true stakes of the story—not just physical destruction, but the collapse of moral and magical order.
Ettore’s death is both a loss and a signal. The old guides are gone, and now the reborn must choose their own paths.
His legacy is caution. And the knowledge that even good intentions can awaken terrible power.
Alarion
Alarion, the Champion of the Light once buried in Undachar, emerges as a damaged, uncertain figure—neither savior nor monster. He is haunted by his own betrayal of the Lady, casting doubt on his loyalty and intentions.
Yet his alliance with the group and willingness to fight Sinclair’s forces suggest redemption. Alarion represents the broken ideal: a once-perfect knight who has fallen but still yearns to do right.
His presence in the group complicates the moral landscape. What does it mean to fight for light when you have already betrayed it?
He may not be central to the final battle, but his symbolism is potent. History’s champions are not flawless, and neither are its villains.
Themes
Identity and Legacy
The theme of identity and legacy is at the heart of Dark Heir, shaping the actions, relationships, and inner struggles of nearly every major character. Will’s arc is dominated by the knowledge that he is the reborn Sarcean—the Dark King of myth—yet he resists the fatalism implied by this legacy.
The book consistently portrays his identity not as a fixed fate but as a field of conflict between inherited memory and present moral choice. Will’s refusal to embrace Sarcean’s darkness, despite being genetically and mystically linked to him, represents a broader rejection of the deterministic view of identity.
The legacy of the Dark King is not just a historical inheritance but a living force that threatens to define Will’s soul and relationships. Similarly, James—once the enslaved Champion Anharion—is haunted by the identity forced upon him.
The narrative complicates the idea of reincarnation by suggesting that memory alone does not determine selfhood. James must reconcile his new self with the painful fragments of the past, especially when those memories involve acts committed under magical compulsion.
The struggle between self-authorship and inherited roles is a continuous pressure point across the plot. It challenges every character to define who they are in a world that demands they fulfill ancient, often violent, legacies.
Dark Heir ultimately argues that identity is both a mirror and a battlefield. One can carry the past without being ruled by it, but it takes extraordinary courage and sacrifice to choose a different legacy.
Power and Moral Choice
Power in Dark Heir is portrayed not as a neutral tool but as a test of character. The narrative interrogates the consequences of power through both mystical and political lenses.
Will, born with immense magical and historical authority, is repeatedly placed in situations where he must decide whether to wield his power at the cost of his humanity. His decision to destroy Dark artefacts, refuse domination over James, and ultimately reseal the Fifth Seal using his own soul illustrates how moral restraint becomes the true measure of leadership.
Power is shown to tempt, corrupt, and isolate—but it can also protect and redeem when used in service of others. James’s journey reflects a parallel truth: strength without autonomy is enslavement.
His past as Anharion—collared and weaponized—demonstrates how the distortion of power robs individuals of agency. Only by reclaiming the right to choose, particularly when he breaks from the role Sinclair expects of him, does James become whole again.
Sinclair represents the antithesis of this philosophy. He consolidates power with the express goal of domination, aligning himself with relics and rituals that strip others of choice.
Visander’s evolution also reflects this theme. While he begins as a rigid agent of Light, bound to destroy the Dark King, he eventually recognizes that true moral action involves discernment, not doctrine.
The novel suggests that power is always a crucible—it reveals, refines, or ruins. Only those who prioritize ethical choice over brute strength can wield it without becoming tyrants.
Trust and Betrayal
Throughout Dark Heir, the theme of trust is explored through shifting alliances, hidden truths, and betrayals—both perceived and real. The dynamic among the main group—Will, James, Violet, and Cyprian—is tense and constantly tested by secrets and suspicion.
Will’s concealment of his true identity, though motivated by fear of rejection, creates emotional fissures that widen as the plot unfolds. When the truth finally surfaces, it almost breaks the group.
The narrative reveals that trust, once fractured, can never be restored to its original state. It must be rebuilt, layer by layer, through action and sacrifice.
James serves as a nexus of both trust and betrayal. Once a servant of the Dark King, then a Steward, and now a conflicted ally, he must earn trust from both sides while questioning his own motives.
His refusal to abandon Will—even when all others are ready to turn on him—reframes the betrayal he committed in his past life. Violet, too, embodies this theme.
Her struggle to reconcile Will’s past with his present leads her to a place of painful loyalty. She represents the burden of trust—how it can feel like betrayal to others when it is extended to someone morally ambiguous.
Betrayal in this story is not always treachery. Sometimes it is the breaking of expectations, the shattering of roles others projected onto you.
The novel’s nuanced portrayal of trust shows how fragile yet vital it is, especially in a world governed by magic, reincarnation, and hidden histories.
Fate versus Free Will
The clash between fate and free will runs through the entire book. Every character must wrestle with whether their path is preordained or if they can make meaningful choices to alter their destiny.
Will’s existence as the reborn Sarcean is the most overt example of this tension. Others expect him to repeat history, but he fights to prove that rebirth does not mean repetition.
His greatest fear is not death, but the loss of autonomy—the idea that he might one day embrace the darkness simply because it is written into his nature. This conflict escalates throughout the story.
Particularly when Will is forced to make decisions that echo Sarcean’s past, such as opening ancient tombs or wielding forbidden power. Each time, he chooses differently, suggesting that fate is a script that can be rewritten with sufficient willpower.
James also embodies this theme. As Anharion, he committed terrible acts under magical control.
In his new life, he seeks not just redemption but control over his future. His relationship with Will becomes a site of freedom—a place where both of them act outside the bounds of prophecy.
Visander, too, is torn between his ancient oaths and evolving understanding of the present. His eventual choice to spare Will, rather than slay him as foretold, becomes a defiant assertion of free will over inherited purpose.
Dark Heir insists that while fate may shape the arena, it does not dictate the outcome. The soul’s resistance to its supposed destiny is the true source of heroism in this world.
