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.

• Voice of the Spheres (broadcasts cosmic frequencies; listeners hear alien harmonies, SAN 1/1d6)

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

Daily Patterns

Knowledge

About the Investigators: He has received word from the Aeternum Choir’s network that cells in London, Lyon, and Venice have been disrupted by “English agents.” He knows they are dangerous but does not yet know their faces, names, or that they have arrived in Vienna.

About the Engine: The Engine is approximately 85% complete as of August 3rd. It can produce sounds but cannot yet perform Segment V of the Grand Canticle. He requires:

1. Anna Lindqvist (soprano component) — currently being acquired
2. A conductor brain of sufficient mathematical sophistication (he has considered using himself but fears loss of agency)
3. Final calibration (three nights of adjustment, August 12–14)

About August 15: The ritual is scheduled for midnight on the Feast of the Assumption. Success would create a Resonant Node in Vienna and bring the Choir one step closer to the Final Chorus.

Weaknesses

• Intellectual vanity: Will explain his work in detail to intellectually interesting listeners, revealing operational details
• Underestimation: Assumes those without his intelligence pose no genuine threat; may dismiss warning signs until too late
• Isolation from consequence: His detachment from the human cost of his work is both strength and weakness — he cannot intuitively grasp why others would try to stop him

Combat

Herzfeld is not a combatant. If cornered, he will attempt to flee or surrender. If forced into physical conflict (extreme circumstances), he is clumsy and weak, relying on psychological dominance rather than force. He will never voluntarily fight to the death.

Spellcasting

Herzfeld can attempt to use Voice of the Spheres as a defensive measure if attackers enter the sealed theatre during the ritual — the harmonic frequencies cause immediate SAN loss and disorientation (SAN 1/1d6, targets must make POW rolls to resist effects).

Interactions with PCs

If Approached Academically

Herzfeld will engage thoughtfully. He sees the investigators as potentially useful sounding boards for his theories. This is dangerous — any genuine intellectual interest will cause him to become loquacious.

If Threatened Directly

He becomes coldly logical. He will not panic. He will assess the threat, determine whether it can be eliminated through Adler’s people, or whether he must accelerate the timeline.

If Confronted About Victims

He will not deny the facts but will reframe them philosophically. “They have become immortal. They are part of something eternal. Their suffering is temporary; their transcendence is permanent.”

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.

Updated Status (11 August 1814)

• Sleep: Not sleeping. Deteriorating.
• Location: University sealed theatre for extended periods, plus his Innere Stadt apartments
• Ritual readiness: Unknown, but the accelerated timeline suggests the Engine is closer to operational than the party realised

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.

Current Status (dawn, 12 August 1814)

• Status: Captured; in Russian custody
• Physical condition: Gunshot wound to right shoulder; face destroyed by Varrio’s feral attack; bandaged, mummified appearance
• Location: Transferred to Major Volkonsky’s operatives for extraction and interrogation
• Psychological state: Unknown. The destruction of the Engine in front of him — the annihilation of his life’s work — may trigger the psychotic break anticipated in existing Keeper notes. His conviction that the work was righteous is the only architecture his sanity rests on, and it has been demolished.

Final Notes

Herzfeld represents clinical, bureaucratic evil — the horror of rationalization, of removing human feeling from atrocity and replacing it with mathematics. He is not a melodramatic villain. He is a man convinced he is right, and that conviction makes him more dangerous than any cackling cultist.

[!info] Keeper Only If captured before the ritual, Herzfeld will initially be defiant but will reveal significant information if threatened with the destruction of his life’s work (the Engine). He values the Engine more than his own life. If the Engine is destroyed while he watches, he may suffer a psychotic break — his sanity dependent entirely on the belief that his work was righteous and necessary.

Relationships

• Leads Brotherhood of the Open Measure — Cult leader; absolute authority
• Serves with Anton Adler — Kapellmeister Adler is second-in-command; Herzfeld directs operations
• Employs Otto von Kaunitz — Baron von Kaunitz serves as intelligence operative and social infiltrator
• Depends on Leopold von Trautmannsdorff — Count provides funding and political protection
• Designed Harmonic Engine — Architect of the Engine; devoted to its completion
• Targets Anna Lindqvist — Soprano component acquisition target; ideal vocal candidate
• Presumed responsible for Wachter Ambush Heuriger Aug 11 — Presumed to have deployed the Wächter that attacked the war council at the Heuriger, or the Engine directed it independently
• Located at University of Vienna — Working around the clock in the sealed anatomical theatre beneath the University
