Gehenna

Gehenna is a power of destruction, consumption, and ownership whose decisive importance lies in the way it turns spiritual life into strength. Jack uses it to seize the essence of the dead, erase the identities of supernatural enemies, and protect humanity from being processed by the Infinity Machine, yet every victory forces him closer to the same logic of conversion that he condemns. The authority therefore functions not merely as an attack, but as a contested answer to the question of whether survival can be secured without reproducing the machinery of atrocity.

Definition and Operation

Gehenna operates directly on mana and spiritual essence. When Jack stands over Lancelot’s corpse, he reaches into the lingering source of the man’s power, described as the essence of his ego and spirit. That spirit cries out in pain and confusion as Jack holds it, and it is otherwise destined to be drawn into Infinity, repurposed, recycled, and returned as an abomination against humanity. Gehenna interrupts that process by allowing Jack to crush the essence and absorb its power.

The act is not a simple transfer of energy. Lancelot’s ego enters Jack’s body and immediately attempts to wrest control from its new host. Jack’s will prevails, and Lancelot’s screams fade into oblivion as his remaining strength becomes Jack’s. This establishes the authority’s full operation: it destroys the captured identity, consumes its power, and makes the victor its owner. Gehenna thus treats consciousness as something that can be forcibly separated, suppressed, and metabolized.

Jack understands this function as the true use of Gehenna: “To destroy. To consume. To own.” He also regards it as a fragment that mirrors the Infinity Machine, but with a crucial difference. Where Infinity would recycle spirits into new horrors, Jack believes Gehenna can cleanse them by destroying them completely. That distinction is the authority’s central moral paradox. It opposes the Infinity Machine by adopting a related process of dehumanizing conversion.

Jack’s Use of Gehenna

Jack’s use of Gehenna is presented as both deliberate judgment and personal burden. After absorbing Lancelot’s power, he wonders about the weight of his own sins, a question sharpened by the fact that he has just claimed another person’s essence. The power gives him an immediate military advantage, but it also makes each victory inseparable from an act of spiritual erasure. Its promised humanitarian purpose cannot remove the violence of the method.

He applies the same authority against an Apostle trapped inside a glass sculpture. Through angelic vision, Jack sees that the being remains alive and is gathering mana for a devastating attack. He activates Gehenna through the sculpture, then declares, “I give you mercy,” before striking through the creature’s carapace and seizing the energy within it. Flames consume the Apostle as it screams. The language of mercy is therefore attached to annihilation: Jack presents destruction as kindness because the alternative is continued danger or a worse fate within Infinity’s system.

The authority becomes still more expansive during Jack’s assault upon Heaven. As demonic hordes attack, several Apostles emerge from the surrounding ruins, drawn by his angelic power. Gehenna, working with Lilith as she devours them, wipes them away. Jack’s anger then destroys a vast area of the citadel, and the narrative records an increase in the “Authority of Gehenna.” Its growth is consequently linked to escalation: the more completely Jack unleashes his rage against the enemy, the greater the authority becomes.

Conflict with Other Powers

Gehenna is not exclusively Jack’s instrument. During the confrontation with Michael, Jack raises his mana and attempts to activate his own Gehenna, but Michael prevents him from launching an attack in that manner. The interruption establishes that the authority can be blocked or constrained, and that possession of Gehenna does not guarantee control over every encounter. Jack must rely on an undisclosed reserve rather than simply overpowering Michael through the same force.

Michael himself radiates the sigils of Gehenna, revealing that the power belongs within the wider conflict among angels and the forces gathered around the Infinity Machine. In the same confrontation, Michael intends to awaken Adam, the first Awakened and first hunter, whose ability to pursue the magically gifted across the globe makes him an existential threat. Sahaqiel recognizes the plan as catastrophic: freeing Adam would allow him to kill the angels and doom the world. Michael rejects that interpretation, claiming that he is repairing rather than destroying the world and presenting the deaths of Sahaqiel and Jack as the foundation of a newer order.

Gehenna therefore marks no simple boundary between hero and villain. Jack uses it against Michael’s plans, but Michael also possesses the same symbolic and practical vocabulary of power. The authority can be framed as salvation, repair, mercy, or cleansing by whoever controls it. Its meaning is determined less by the name attached to it than by the fate imposed upon the beings caught within its reach.

Defensive and Collective Applications

Gehenna can also be used defensively and through cooperation. When Michael moves against Sahaqiel, Ruby’s black chains obstruct the archangel’s path, amplified by Lilith. Michael attempts to cut down the specter, but his attack strikes a shield augmented by Gehenna and fails to pass through it. The authority therefore does more than consume targets: it can reinforce a barrier, strengthen an ally’s intervention, and alter the outcome of a direct clash with an archangel.

This defensive use complicates Gehenna’s prevailing image as an appetite. The same power that dissolves Apostles and absorbs the dead can protect a vulnerable companion. Yet the scene does not erase its destructive character. The shield’s effectiveness depends on the same force that elsewhere takes possession of bodies and spirits, so protection and annihilation remain neighboring expressions of one authority.

Moral and Narrative Significance

Gehenna embodies the book’s recurring conflict between survival and the methods used to achieve it. Selfia justifies a purge of 369 lives, and possibly more, as necessary to secure the advent of the New Republic; Jack condemns the resulting chaos, including the deaths of bystanders and innocents, and rejects the claim that murder can be made necessary through political language. Against that background, Gehenna gives the debate physical form. It offers Jack a way to prevent spirits from becoming weapons for Infinity, but it does so by destroying the individual self and adding the stolen power to his own.

Its operation also turns the body into a contested political and metaphysical territory. Lancelot’s spirit enters Jack and attempts to seize control, while Jack’s victory converts another person’s identity into an internal source of strength. The authority’s danger is therefore not limited to what it does to enemies. It threatens the boundaries of the user as well, making power an accumulation of conquered selves even when those selves are finally silenced.

The repeated invocation of mercy creates the authority’s sharpest irony. Jack says “I grant you mercy” while crushing Lancelot’s essence, and “I give you mercy” while killing the trapped Apostle. Mercy ordinarily preserves or releases life; under Gehenna, it means preventing further exploitation by ending the subject entirely. That contradiction makes the authority a material expression of Jack’s desperate moral compromise: he seeks to cleanse a world dominated by monsters, but his chosen means resembles the world’s most terrifying machinery. Gehenna’s increasing strength consequently carries no uncomplicated triumph. Each advance in power is also an advance in the capacity to destroy, consume, and own.
