August Ruthven stands as a central architect in vampire history, instrumental in halting the prolonged war between humans and vampires. Once a teacher and peace advocate, he pursued reconciliation during the conflict, forging alliances with figures such as Chloé d’Apchier of House d’Apchier to study the World Formula and its Alteration Device. His ambitions fractured in 1672 when his students, Éric and Louise—Jeanne’s adoptive parents—betrayed him, exposing vampire secrets to humans. Their execution and Jeanne’s conscription as a Bourreau followed, while Ruthven survived an ambush that cost him his right eye, igniting a profound shift in his ideology. The betrayal propelled Ruthven toward ruthless pragmatism. He climbed the ranks of vampire society by mastering political maneuvering, securing guardianship over Luca Oriflamme, the Grand Duke, and later joining the Senate. By orchestrating the 1702 armistice, he exiled vampires to Altus, a pocket dimension born from the Babel Incident. Though hailed as a peacemaker, his tactics grew shrouded in secrecy and moral compromise. Ties to the clandestine Charlatan organization saw him propagate Malnomen via Naenia, endorse Doctor Moreau’s experiments on curse-bearers, and enable the Bal Masqué assassination attempt on Luca, exposing his tangled allegiances. Ruthven’s relationships hinge on calculated manipulation. He shields Luca from harm yet stifles his efforts to cure Loki’s curse, balancing protection with control. His interactions with Jeanne blend superficial warmth with exploitation, leveraging her Bourreau role for political gain. Once a collaborator, Chloé became a target when he sought to curse her and seize the Alteration Device, severing their alliance. His rivalry with the Shapeless One, Noé’s mentor, underscores his enduring grip on vampire politics as he counters ideological dissent. Ruthven’s prowess lies in both supernatural and strategic dominance. He commands black flames capable of instantaneous annihilation, deployed sparingly to enforce authority. His strategic brilliance surfaces in schemes like Noé’s coerced obedience oath, weaponizing the youth’s ties to the Shapeless One. Psychological warfare—such as Naenia’s hallucinatory manipulations—reveals his readiness to exploit weaknesses, though his alignment with her remains enigmatic. His trajectory shifts from idealistic peacemaker to calculating pragmatist, sacrificing ethics for perceived greater stability. Actions like covertly enabling atrocities while advocating balance between species reflect his mantra that “salvation takes many forms,” justifying coercion or violence as necessary tools. Rooted in John Polidori’s *The Vampyre*, his morally ambiguous legacy cements him as a cornerstone of vampire lore, embodying the tension between noble intent and ruthless execution.
