CRACK — The Disaster Begins
One day, without warning, it opened like an animal's jaws. Skies around the world turned the color of spilled blood. With a deafening crack, red rifts tore open at once and swallowed entire buildings. A disaster. A total, absolute disaster. The phenomenon that ripped sky and reality apart like meat was given a name: CRACK.
Ordinary life shattered. More than 15% of humanity was swallowed alive by CRACK. The survivors faced a murderous presence beyond reason. Here, some remain trapped in a hellish high school, where slaughter and impossible distortions fill an after-school hour that never ends. Keep your breathing quiet. This is your story, written in blood and despair.
"The world we knew has already rotted away. And this school is nothing but a slaughterhouse that breathes."
CRACK — Severed Spacetime
Where CRACK opens, reality is skinned away and Distortion takes hold. Spacetime twists like tangled entrails. The affected area is cut clean out of the real world and sealed away.
No one outside can reach in. Even calls for rescue are crushed into cold static. Wherever they were when CRACK struck, its victims are buried alive in a warped labyrinth ruled by alien laws. Amid torn flesh and shattered bones, not a single person has been found who escaped this hell alive.
Distortion — Broken Laws
A place caught at the heart of CRACK undergoes terrible changes. The school has become a vast prison, its interior twisting, shifting, tangling, and expanding without end.
At irregular intervals, the school screams and resets its layout. A third-floor music room sprawls across tens of acres and drops onto the first floor. Straight hallways stretch into endless mazes. School rules twist into something stranger, and breaking them brings real consequences. Pockets of empty Void interrupt stairways without end. Every room swells into another impossible labyrinth. Was I going up the stairs? Down? Falling through the floor? Are my legs even still attached? I don't know anymore.
Anomalies
Bizarre beings with their own rules appear throughout the distorted space. We call them Anomalies. They fall into two groups: physical Monsters that crush warm flesh and bone, and bodiless Aberrations that exist as phenomena, rules, or something we cannot define.
[ Anomaly Ranks ]
[Rank: Echo]
Incomplete fragments: voices, visions, slight physical forces, or minor rules. Some are bodiless; others are no bigger than a rabbit. Their direct impact may be small, but ignoring them is not safe. They can gnaw at sanity until it breaks. Violate even an Echo's smallest rule, and a horrific chain reaction may bring sudden bleeding and mutilation.
[Rank: Manifestation]
Monsters or Aberrations that roam with a distinct form or purpose. Their twisted rules make them extremely dangerous. Don't rush into a fight. Learn their behavior and rules quickly, then find any way out.
[Rank: Nightmare]
A disaster that has become the very rules of a place. Monster or Aberration, overcoming one is nearly impossible. Some demand a sacrifice. They are unfair, overwhelming things. Face one, and the will to fight gives way to a single hope: let death be painless.
[Rank: Void]
Catastrophe. A mythic presence that brings despair the instant you encounter it. Nothing remains but awe. And prayer.
