Albin Herzfeld

Overview

Professor Albin Herzfeld is a 47-year-old music theorist, mathematician, and occultist who leads the Vienna chapter of the Aeternum Choir. He is the designer of the Harmonic Engine and has transformed the sealed anatomical theatre beneath the University of Vienna into a construction site for his vision of “perfect harmony” — achieved by mechanizing the human components of sacred music.

Herzfeld genuinely believes he is elevating humanity, not murdering it. He does not see his victims as people but as raw materials, imperfect instruments to be refined and incorporated into something transcendent.

Physical Description

Tall and gaunt, Herzfeld moves with precise, economical gestures. He wears wire-rimmed spectacles perpetually smudged with chalk dust. His fingers are ink-stained from hours spent writing musical notation. His eyes are the most unsettling feature — pale blue, intense, and they seem to look through people rather than at them. He dresses in dark academic robes, and his appearance suggests a man who has sacrificed physical comfort in service to intellectual pursuits.

Personality

Cold, clinical, utterly convinced of his righteousness. Herzfeld approaches the grotesque work of the Engine with the detached precision of a natural philosopher conducting an experiment. He does not enjoy cruelty — he simply does not register it as morally relevant. To him, individual suffering is negligible against the goal of achieving perfect, error-free sacred music.

Key Traits:

• Intellectual vanity: Cannot resist explaining his theories to anyone who shows genuine interest
• Underestimation: Dismisses those of lesser intellect until too late
• Conviction: Genuinely believes he is serving a higher purpose
• Isolation: Has lost the ability to see victims as human

Session Appearances

Herzfeld should be present but peripheral in early sessions (Sessions 7–8), becoming increasingly visible and dangerous as the investigators close in. He should never be directly confronted until the climactic ritual night (Session 10, August 15).

Session 12 Update — Accelerating; Timeline Shifted (11 August 1814)

Intelligence extracted from Werner Bauer during interrogation at Thaliastraße 12 confirmed the following:

• Herzfeld has not been sleeping. He is spending extended time in the sealed theatre beyond his usual evening pattern. This is visible even to hired muscle like Bauer who is not privy to the academic work.
• The ritual timeline has shifted from August 15 to August 13. This compresses the party’s window by two days. The assault is now planned for pre-dawn 12 August.
• Presumed responsible for the Wächter attack at the Heuriger. The Wächter that attacked the war council was almost certainly deployed by Herzfeld, or activated by the Engine itself in response to the proximity of the fork. Whether Herzfeld directed it consciously or the Engine acted semi-autonomously is not yet established.

Session 14 Update — Captured; Engine Destroyed (Pre-dawn, 12 August 1814)

The assault teams breached the Sealed Anatomical Theatre simultaneously from two entry points. Herzfeld was at the centre of the Harmonic Engine, performing surgery on Caroline Hartley — cutting into her throat to extract her vocal cords for integration into the Engine.

The Assault

• Adrien’s rifle shot struck Herzfeld in the shoulder, disrupting the surgery and staggering him away from Caroline. This bought the rescue team time to reach her.
• Georgiana struck the Command Tuning Fork against her sword, channeling the counter-ritual. The counter-vibrations muted the ritual’s harmonic pressure and shut down the Engine.
• Varrio, in a feral state, attacked Herzfeld with teeth and fingernails — tearing at his face. Herzfeld was left faceless: the skin shredded, features obliterated.
• Captain Ferrante physically restrained Herzfeld, hauling him away from the machine by the scruff of his neck.

Aftermath

Herzfeld was wrapped in bandages — a mummified appearance, the face beneath the dressings destroyed. He was handed over to Russian operatives under Major Andrei Volkonsky’s command for custody and intelligence extraction.

The Harmonic Engine putrefied and collapsed when the counter-ritual shut down the ritual’s harmonics. The flesh-and-brass structure sagged, rotted, and fell apart under its own weight. Herzfeld’s life’s work is gone.
