Campaign Book: 6th Grade

The following mystery is part of a larger campaign book titled 6th Grade, which is divided into four marking periods. Each marking period introduces new scenarios, escalating threats, and evolving character arcs as players navigate the strange and supernatural undercurrents of middle school life. While each marking period is self-contained, they collectively reveal a larger, overarching issue that unfolds across the entire campaign.

Marking Period 1: Mystery - The Substitute and the Forgotten Holiday

Overview: A substitute teacher arrives mid-semester with no prior notice. He carries an unsettling presence and introduces lessons that seem to alter students' memories. Overnight, the school is decorated for a holiday no one remembers planning. Staff behave as if it's a long-standing tradition, while students feel increasingly disoriented.

Overview: A new student arrives at the school under mysterious circumstances. Quiet and observant, they seem unnerved by something others can't see.

NPC: Mysterious New Student

Name: TBD

Background: A new student has recently transferred to the school and is struggling to fit in. Quiet and observant, they often keep to themselves and seem unnerved by something others can't see. Rumors swirl about their connection to strange happenings in the school.

Personality:

Role in the Story: The student begins to notice odd behavior from the lunch ladies, who seem to be guarding something. Their investigation leads them to discover a hidden passage in the basement that opens into an ancient, eerie temple. The temple pulses with dark energy, and its presence seems to be influencing the staff. The student may become a key ally or informant for the player characters, offering clues and insight into the mystery.

Plot Hooks:

Connection to the Temple: The student may have a latent connection to the temple, possibly through ancestry or a forgotten pact. Their presence at the school may not be a coincidence.

Scenario: The Janitor’s Closet That Shouldn’t Exist

Premise: A student goes missing after detention. The only clue? Their backpack was found inside a janitor’s closet that no longer appears on any map—and seems to shift location each day. The closet is impossibly deep, filled with flickering lights, whispering vents, and cleaning supplies that seem... wrong.

Setting Details:

• The Closet:

• Appears in different hallways each morning

• Inside, the space warps—sometimes a narrow crawlspace, sometimes a vast industrial chamber

• Smells like bleach and something older, like mildew and rot

• A mop bucket occasionally moves on its own

• The Janitor:

• Never seen entering or leaving

• Always humming a tune no one recognizes

• Eyes glow faintly when caught in fluorescent light

• May be a guardian, prisoner, or something else entirely

Plot Hooks:

• A player receives a note: “Don’t follow the humming.”

• A second student vanishes, but their phone livestreams from inside the closet

• The janitor offers a player a key “for when it’s your turn to clean”

• A lunch lady warns, “That closet’s not ours. It’s theirs.”

Connection to the Temple: The closet may be a satellite chamber of the temple—an access point for rituals, storage, or punishment. The janitor could be a temple-bound entity, maintaining the school’s illusion of normalcy while hiding its true architecture.

🪚 Scenario: The Last Tenant

Premise:
In a condemned apartment tower on the edge of the city, a group of urban explorers breaks in to document the final night before demolition. But the building isn’t empty. Something stalks the halls—something that’s lived there longer than any lease. The elevators still run, but only go down. The killer wears a patchwork coat made from tenant eviction notices and moves through the walls.
Setting Details:
• The Tower:
• 30 floors, most sealed off
• Graffiti that changes when no one’s looking
• Lights flicker in patterns—almost like Morse code
• Every apartment has a different temperature and smell
• The Killer (“The Last Tenant”):
• Appears as a silhouette behind frosted glass
• Leaves behind keys that don’t open anything
• Kills with tools left behind by former residents—curling irons, broken fans, rusted knives
• Whispers eviction threats before striking
Plot Hooks:
• A player finds a lease with their name on it, dated tomorrow
• The building’s blueprints show 29 floors, not 30
• A survivor claims the killer is the building itself
• A player receives a voicemail from a number that hasn’t existed since 1993
Tone & Playstyle:
Claustrophobic, paranoid, and surreal. Perfect for tight corridors, unreliable lighting, and trust-breaking moments. Players may need to split up to survive—but that’s exactly what the killer wants.

Scenario: Hall Pass to Hell

Premise: A group of students receives detention for a prank gone wrong. They’re sent to clean the east wing after hours—but the lights flicker, the doors lock, and something begins hunting them. One by one, they vanish, leaving behind bloodied hall passes and cryptic messages scrawled in permanent marker.

Setting Details:

• The East Wing:

• Abandoned after a fire years ago, but still used for punishment

• Smells of smoke, melted plastic, and old sweat

• Lockers rattle even when empty

• Windows show scenes from other nights

• The Entity:

• Appears as a student in a scorched uniform

• Can only be seen in reflections

• Leaves behind hall passes soaked in blood

• Knows each student’s worst fear

Plot Hooks:

• A player finds a hall pass with their name and the word “RUN”

• A survivor from a previous detention refuses to speak, only draws burning doors

• A teacher insists the east wing was never rebuilt

• A mirror shows a player being chased, even when they’re alone

Connection to the Temple: The east wing may be a sacrificial ground tied to the temple’s rituals. The entity could be a failed vessel, still bound to the school and seeking new victims to complete its transformation.

Scenario: Camp Red Fog

Premise: A group of teens arrives at Camp Red Fog for a weekend retreat. The lake is still, the cabins are quiet, and the fog never lifts. On the first night, one camper goes missing. By morning, their tent is shredded and a trail of blood leads into the woods. Something stalks the camp—wearing the faces of the missing.

Setting Details:

• The Camp:

• Surrounded by dense forest and a lake that reflects nothing

• Cabins creak even when empty

• The fog muffles sound and distorts vision

• Cell phones only show static

• The Stalker:

• Appears as a friend, until it’s too late

• Leaves behind masks made of bark and teeth

• Can’t be seen directly—only in peripheral vision

• Knows campers’ secrets and mimics their voices

Plot Hooks:

• A player finds a mask with their own face

• A campfire story matches real events from the night before

• A counselor insists the camp was closed years ago

• A player hears their name whispered from the lake

Connection to the Temple: The camp may sit atop a buried temple site. The fog could be a protective veil or a containment field. The stalker may be a temple guardian—or a failed ritual that escaped its bounds.

Monster Hunt: The Woods Beyond

Setting: The quest takes place in the dense, overgrown woods just beyond the edge of town. Rumors have circulated for years about strange sightings and eerie sounds coming from the forest, but most adults dismiss them as local legends.

Hook: After a classmate goes missing during a weekend hike, the players receive a cryptic message scrawled on a torn piece of notebook paper: "It lives in the trees. Don't follow the lights."

Objective: Track down the missing classmate and uncover the truth behind the mysterious creature said to haunt the woods.

Challenges:

Twist: The monster is a manifestation of forgotten childhood fears, feeding off the anxieties of local kids. Defeating it requires more than brute strength—it demands understanding and confronting personal fears.

Resolution: The players rescue their classmate and return with newfound confidence and insight, setting the stage for deeper mysteries in the next marking period.

Monster Hunt: The Forgotten Playground

Setting: Hidden behind a crumbling fence and overgrown hedges lies an abandoned playground that once belonged to a now-demolished elementary school. Rusted swings creak in the wind, and the sandbox is filled with strange symbols etched into the dirt.

Hook: A group of students dares the players to spend a night at the playground, claiming it's haunted by the ghost of a child who vanished decades ago. That night, the players begin to experience surreal visions and hear whispers from the shadows.

Objective: Uncover the truth behind the ghostly presence and the history of the forgotten playground.

Challenges:

Twist: The ghost is not malevolent but trapped in a loop of fear and confusion. The players must help it remember who it was and why it lingered.

Resolution: By helping the ghost find peace, the players gain insight into the emotional weight of memory and loss, deepening their connection to the supernatural forces at play in the campaign.

Monster Hunt: The Drain Below

Setting: Beneath the town’s skate park lies a forgotten storm drain system—twisting tunnels, rusted grates, and graffiti-covered walls. Strange noises echo from below, and local pets have started disappearing.

Hook: A beloved neighborhood dog vanishes near the drain entrance. The players find its collar tied to a pipe with a note: "It’s hungry again. Don’t let it out."

Objective: Descend into the storm drain to investigate the disappearances and confront the lurking entity.

Challenges:

Twist: The monster is a parasite that feeds on loneliness and neglect—its form shifts based on the fears of whoever enters. It’s been growing stronger by feeding on forgotten places and abandoned feelings.

Resolution: The players must weaken the creature by rekindling memories of connection—using shared stories, recovered objects, or acts of kindness. If they succeed, the drain collapses inward, sealing the entity and restoring peace to the neighborhood.

Monster Hunt: The Radio Tower

Setting: On the outskirts of town stands a long-abandoned radio tower, its skeletal frame looming over the hills. The tower occasionally emits strange signals that interfere with local electronics and cause vivid hallucinations.

Hook: A student working on a science fair project picks up a bizarre transmission from the tower. When they go to investigate, they vanish—leaving behind a journal filled with erratic entries and coded messages.

Objective: Ascend the radio tower to uncover the source of the signal and rescue the missing student.

Challenges:

Twist: The signal is a psychic beacon sent by a creature trapped between dimensions. It seeks to merge realities to escape its prison, but doing so would unravel the fabric of the players’ world.

Resolution: The players must sever the signal and stabilize the dimensional rift, saving their classmate and preventing a catastrophic collapse of reality.

Monster Hunt: The Video Store Vault

Setting: Tucked behind a boarded-up strip mall is an old video rental store, long abandoned but still faintly humming with electricity. The shelves are dusty, the tapes warped, and a flickering “OPEN” sign glows despite no power source.

Hook: A student finds a strange VHS tape labeled “Do Not Watch Alone” and disappears after viewing it. The players discover the store has reopened itself—just for them.

Objective: Enter the video store, uncover the mystery behind the cursed tape, and rescue the missing student before they’re trapped in the footage forever.

Challenges:

Twist: The monster is a sentient glitch—a corrupted narrative entity that feeds on unresolved stories and emotional dissonance. It uses the players’ own memories to rewrite reality.

Resolution: The players must rewrite the tape’s ending by confronting their own emotional truths, restoring the missing student, and sealing the vault before the glitch escapes into the real world.

Monster Hunt: The Cafeteria Showdown

Setting: The school cafeteria, usually bustling with noise and trays of mystery meat, becomes the site of a terrifying showdown when a monstrous entity emerges from the walk-in freezer.

Hook: After a series of strange food-related incidents—students falling ill, meals moving on their own, and eerie whispers from the kitchen—the players are called in to investigate.

Objective: Uncover the source of the cafeteria disturbances and defeat the creature before it spreads its influence throughout the school.

Challenges:

Twist: The creature is a fusion of discarded food and forgotten lunchroom memories, animated by resentment and neglect. It seeks recognition and revenge for years of being ignored.

Resolution: The players must confront the monster’s emotional core, offering acknowledgment and closure. If successful, the cafeteria returns to normal—though the mystery meat remains suspicious.

🧪 Monster Fight: Science Fair Meltdown Setting: The school gymnasium, transformed into a bustling science fair. Tables are lined with bubbling volcanoes, solar-powered contraptions, and questionable slime experiments. But something’s wrong—one of the projects has started mutating. Hook: A student’s “bio-reactive goo” project explodes mid-judging, releasing a rapidly growing creature made of fused science fair materials. It absorbs other projects, warping into a multi-limbed monstrosity. Objective: Contain and defeat the creature before it escapes the gym and spreads through the school. Challenges:

The Forest Remembers

Premise: A group of students heads into the woods for a weekend camping trip. But as night falls, they begin to notice strange patterns in the trees, whispers in the wind, and signs that someone—or something—has been watching them long before they arrived. Their campsite seems to shift, trails loop back on themselves, and memories of the trip begin to blur.

🕳️ Scenario: Beneath the Neighborhood

Premise Strange smells and tremors have been plaguing the neighborhood for weeks. When a group of students investigates a blocked storm drain, they discover a hidden network of tunnels beneath their town. The deeper they go, the more they realize the sewers are not abandoned—they're inhabited by something ancient, hungry, and aware.

One night, the kids witness a terrifying creature attacking a man in the tunnels. But as they investigate further, they uncover a shocking truth: the man was a doppelganger, a perfect mimic of someone from the surface. The sewer creatures, though monstrous in appearance, are guardians who protect the town from these imposters.

Determined to stop what they believe is a threat, the kids descend into the sewers to banish the monster. But as they navigate the tunnels, decipher cryptic warnings, and survive strange encounters, they begin to understand the truth. The monster is not their enemy—it is their ally.

Together, they uncover a chilling revelation: one of the students' parents has been replaced by a doppelganger. With the sewer guardian's help, they must confront the imposter, expose the truth, and protect their family and town from further infiltration.
