The Vernal Cogwheel's Tremor

Caspian grapples with the mounting unease surrounding the Vernal Cog-Fête, as strange mechanical failures and eerie phenomena plague the city. Amidst banter with his friends, a deeper, more unsettling truth about their community's impending celebration begins to surface.

# The Vernal Cogwheel's Tremor
**Format:** Short Film / Anthology Episode | **Est. Length:** 10-12 minutes

## Logline
In a sprawling steampunk city, a perceptive young mechanic senses a growing, supernatural malevolence corrupting their technology and must convince his skeptical colleagues of the danger before an upcoming festival triggers a city-wide catastrophe.

## Themes
* **Intuition vs. Empiricism:** The conflict between Caspian's gut feelings about a deeper wrongness and the purely logical, mechanical explanations favored by his peers.
* **Progress vs. Nature:** The tension between the city's advanced steam-powered society and the ancient, primal energies of the earth it has built upon and suppressed.
* **Collective Blindness:** A community's willful desire to focus on celebration and morale, actively ignoring escalating warning signs that threaten its very foundation.

## Stakes
The very soul of their clockwork city and the lives of its citizens are at risk if Caspian cannot uncover the source of the mechanical corruption before it hijacks the city-wide Vernal Cog-Fête.

## Synopsis
Caspian, a gifted young mechanic, is troubled by a subtle but pervasive "tremor" running through the city's clockwork mechanisms—a cold, deep shudder that feels unnatural. While the city prepares for the annual Vernal Cog-Fête, a celebration of ingenuity, Caspian sees only signs of decay: flickering streetlights, sputtering steam vents, and malfunctioning automatons.

His concerns are dismissed during a planning meeting with his colleagues. Bea, the optimistic organizer, is focused on boosting community morale, while Juno, a cynical and pragmatic engineer, attributes the problems to simple mechanical failures. Caspian tries to explain his theory about a sentient "feedback loop" in the new power conduits, but is met with ridicule. Only Sammie, the elderly keeper of the workshop's historical artifacts, gives his concerns weight, speaking of the city's "memory" and the old, wild energies that stir in the spring.

The debate escalates when Caspian presents a clockwork bird whose spring mechanism is inexplicably and irreversibly seized. When Juno touches it, a spark of static electricity jumps to her hand, rattling her skepticism. Sammie reveals an ancient, glowing fossil, explaining that the city's technology is chafing against a primal energy from the earth below, an energy that is now awakening. As he speaks, a long-deactivated automatronic dog in the workshop jolts to life. Its eyes glow with an eerie light, and a distorted, guttural whisper emanates from its speaker, proving that the threat is not only real and intelligent, but it is now aware of them.

## Character Breakdown
* **CASPIAN (20s):** A brilliant, intuitive, and sensitive mechanic. He is more attuned to the city's rhythms than anyone else, but his quiet nature and esoteric theories make him hesitant to speak up for fear of ridicule. He is the city's reluctant Cassandra.
* **Psychological Arc:** **Start:** A worried and isolated observer, questioning his own perceptions and afraid to challenge the group's consensus. **End:** Vindicated in his fears and thrust into a position of responsibility, forced to transition from anxious observer to active defender against a threat no one else initially understood.
* **BEA (30s):** The workshop's vibrant, energetic leader. A fierce believer in community spirit, she is determined to make the Vernal Cog-Fête a success to lift morale, causing her to initially downplay the severity of the city's problems.
* **JUNO (30s):** A sharp-witted, pragmatic engineer. Grounded and deeply skeptical, she trusts only what she can disassemble and measure. Her cynicism is a defense mechanism, but she is shaken when confronted with evidence that defies her logical worldview.
* **SAMMIE (70s):** The quiet, wise historian of the group. Where others see gears and pistons, Sammie sees a living history. He is the bridge between the city's modern technology and its forgotten, mystical past.

## Scene Beats
1. **THE TREMOR:** In the quiet of his workshop, Caspian feels an unnatural tremor in a small brass gear. He senses it's not a mechanical flaw but something deeper, colder—a shiver in the city's bones.
2. **A FESTIVAL OF DENIAL:** Bea rallies the team to brainstorm "audacious" ideas for the Vernal Cog-Fête. Juno counters with cynical remarks about recent city-wide malfunctions, while Caspian remains silent and troubled.
3. **A SENTIENT SYSTEM:** Prodded by Bea, Caspian nervously shares his theory about a sentient resonance in the city's power conduits. Juno scoffs, but the elderly Sammie cryptically speaks of the city having a "memory" that stirs in the spring.
4. **EVIDENCE OF CORRUPTION:** Caspian presents a broken clockwork bird with an inexplicably seized spring as proof that the malfunctions are not random. He argues something is deliberately "corrupting" their technology.
5. **THE UNSEEN HAND:** Juno, attempting to debunk his theory, touches the inert bird and receives a startling static shock, a physical manifestation of the unseen energy that momentarily shatters her composure.
6. **THE OLD ENERGIES:** Sammie unveils a glowing, petrified fern, explaining the conflict between the city's steam-powered order and the raw, ancient energy of the land it was built on, which is now awakening for the Vernal Equinox.
7. **THE AWAKENING:** As Sammie finishes, a deactivated automatronic dog lurches to life. Its eyes glow with an eerie green-blue light, and a distorted, inhuman whisper emanates from its vocalizer, as the entire city outside begins to hum with a terrifying, malevolent energy. The threat is no longer theoretical; it is active and watching them.

## Visual Style & Tone
The visual style is "foundry-steampunk," emphasizing grimy, well-used brass, copper, and iron over polished ornamentation. The world is lit by the warm, ambient glow of boilers and gas lamps, which is increasingly contrasted and corrupted by a sickly, pulsating green-blue light emanating from the malfunctioning technology. The atmosphere is dense with steam, smoke, and the smell of oil and ozone.

The tone is one of creeping technological horror and folk mystery. It begins with a sense of quiet unease and builds slowly toward palpable dread, focusing on psychological tension rather than overt action. Tonal comparisons include the technological paranoia of **Black Mirror**, the slow-burn atmospheric dread of **Annihilation**, and the lived-in, decaying world-building of **Dark City**.
