ONE-ACT, ONE-SCENE ADVENTURE

“THE HUM IN THE WALLS”

A Shadows of the Veil Micro-Adventure, for Dark Evolution by Worlds of Pulp™
By T. Glenn Bane

---

Ah, then what is horror? In the forgotten corners of East Grayslate, where the streetlamps flicker like dying fireflies and the night itself seems to hold its breath, there lurks a tale of such delicate dread that even the bravest soul might hesitate before stepping across its threshold. Here, in a rowhouse long abandoned by hope and memory, a soft and terrible humming seeps through the walls—beckoning, cajoling, promising revelations no mortal mind was ever meant to endure. It is a place where shadows listen, where the air trembles with the electric ache of a child’s awakening terror, and where those who enter must decide whether they seek truth… or simply wish to survive it.

Premise

There are moments in life when the world tilts—just a fraction—revealing the machinery beneath the façade. Tonight, your characters stand at such a precipice, in the back room of a condemned rowhouse where the wallpaper peels like dying skin and something behind it… hums.

This is a single-scene pressure cooker, designed to play in 60–120 minutes, or longer if your group chooses to wrestle with the impossible decision at its heart.

THE SCENE: “THE HUM”

Location

1437 Brindle Row, East Grayslate District—the sort of forgotten corner of the city where even the streetlights seem too frightened to glow. Neighbors whisper about strange lights and “singing walls,” but in this part of town, folks mind their business hard enough to break teeth.

Inside:
A living room preserved in dust and stale memories. A TV from the early ‘90s. A shabby sofa with a sheet draped over it. And beyond a narrow hallway, the locked back room where the client swears their missing son disappeared “without opening the door.”

The door does not open normally.
The hum coming from behind it is not mechanical.
And the light—pale, pulsing, almost breathing—leaks lightly from the seams.

THE ACT BEGINS

Opening Beat: Arrival

The characters arrive at Brindle Row after being contacted by Mara Kinsey, a Veilkeeper courier with the permanent squint of someone who’s seen too much classified truth.

Her message was simple and cold:
“A child went missing. The W.E.B. wants him back. Find him first.”

When she speaks, her voice trembles—not with fear, but urgency.

“Listen—something’s wrong in that room. When the boy vanished, the W.E.B. sweepers showed up within eight minutes. Eight. That means this isn’t just a kidnapping. This is a breach.”

She leaves them with a burner phone, a set of old brass keys, and a shaking whisper:
“If you hear whispering from the wallpaper, do not answer it.”

THE BACK ROOM

Getting In

Once the characters force or finesse the door open, the hum grows louder—felt not through the ears, but the teeth.

Inside is a small bedroom. Childhood posters. Toys. Sketchbooks.

And on every wall, hundreds of thumbtack holes forming spiraling patterns.

A circular scorch mark stains the center of the floor.

On the bed sits a boy wrapped in a hospital blanket, rocking slightly. His eyes shimmer like the blue of a gas burner. Thin trails of smoke coil from his tear ducts.

He looks at the characters.

And the hum stops.

Dead silent.

He says:

“I didn’t mean to bring them here.”

---

THE TWIST: “THEM”

A ripple moves through the walls—subtle as a passing subway, yet wrong in every direction. The wallpaper begins to bulge outward, forming the rough outlines of faces: some screaming, some laughing, some simply watching with empty sockets.

These are echoes of warped psychic impressions, accidental manifestations created by the boy’s awakened mind.

No ghosts.
No spirits.
Just psychic residue given the cruelest form imagination can conjure.

And then—

They speak.
In different voices.
But in perfect unison.

“HE IS OUR OPEN DOOR.”

---

STAKE REVELATION

The boy, Caleb Dorn, is the product of a new Ravenesque deviation: exopsychic resonance implants.
W.E.B. didn’t just amplify his mind—they loosened the knots that anchor human consciousness to the physical plane.

He is, in effect, a psychic breach point.

If he panics, the walls split.
If he screams, dimensional membranes tear.
If he falls asleep, the entities on the other side finish stepping through.

He clutches his blanket and whispers:

“They want to finish wearing me.”

---

THE PRESSURE

Just as the characters begin processing this…

BOOM.
The front door explodes inward.

W.E.B. Sweep Team Kestrel enters the house—four operatives in matte armor, each carrying non-lethal capture rigs and neural dampeners.

Their orders are clear:

• Retrieve the boy alive.
• Neutralize all witnesses.

They shout from the hallway:

“Step away from the subject! He is unstable!”

Caleb screams.

The wallpaper splits open.

Hands—too many, jointed wrong—push through.

THE CHOICES

This single scene is built entirely around one impossible decision:

1. Save Caleb

Protect him from the W.E.B., calm his mind, and stabilize the breach.

Requires:

• Empathy, persuasion, psychic shielding—or raw courage.
• Someone risking direct contact with the warped psychic impressions.

Outcome:

• The breach subsides.
• Caleb bonds to the group.
• The W.E.B. escalates dramatically.

2. Surrender Him to W.E.B.

This ends the scene quickly, brutally, and cleanly.

Outcome:

• W.E.B. thanks the characters… ominously.
• Caleb is carted off to a laboratory where fate is sealed.
• The Veilkeepers brand the characters as compromised.

3. Destroy the Breach by Force

Killing or sedating Caleb violently collapses the psychic rupture.

Outcome:

• Reality stabilizes violently—everyone takes mental/physical damage.
• Sweep Team Kestrel goes feral with grief and fury.
• The Veilkeepers sever ties.

4. Use the Breach

A desperate or reckless character may try to touch the rip—seeking:

• power
• knowledge
• escape
• revenge

Outcome:

• The character gains a psychic ability…
• …but at catastrophic Strain, causing immediate hallucinations, nosebleeds, or worse.
• The entities “notice” the group.
• Long-term consequences ripple through the campaign.

SCENE ENDING

No matter the choice, the rowhouse collapses inward as the breach closes—whether by healing, termination, or violent inversion.

Dust settles. Sirens echo.
The night fractures into conspiracy and consequence.

And somewhere in the distance, the W.E.B. radio network crackles with a chilling phrase:

“Subject Theta has been accounted for. Prepare the next vessel.”

GM NOTES

• This scene is designed for players to feel the full weight of moral horror, not combat grinding.
• Lean into sensory dread: vibrating floorboards, whispering drywall, blood-hum in the air.
• Use the boy not as a monster, but as a tragedy.
• Sweep Team Kestrel should be efficient, emotionless, chillingly polite.

This is horror born not of the supernatural,
but of humanity’s appetite for evolution without mercy.
