"Dead worlds.
Planets ravaged by apocalypse.
It is often said that dead worlds are barren; devoid of life; desolate.
However, one should never blindly believe everything they hear.
For somewhere in our universe, hidden deep inside these barren worlds might lie-"
Crash. The soft female voice went silent.
The little girl jumped at the sound of breaking glass, dropping the old Walkman she was holding. A few seconds later her mother came running into the room, panic evident in her eyes. She took in the sight of her daughter, standing still and staring across the room, with the silent Walkman at her feet - the cassette having popped out of the device from the shock of the fall - and the broken glass on the floor by the window and let out a sigh of relief.
Across the room, on a display table by the open window - having seemingly jumped in through said window and pushed a glass vase off the edge of the table - sat a white cat, quietly licking it's paw.
The womam quickly picked up the little girl and shooed away the cat before carrying her daughter into the living room, away from the glass shards. Handing her a sloth plush toy after setting her down on a settee, she headed off to clean up the broken glass. Then she turned her attention to the Walkman.
While it had opened from the shock of the fall, there seemed to be no damage to the casing itself. It was an old model her grandfather had used in his youth. The woman had found it in a box of old items while emptying out their attic and simply placed it on a shelf beside the framed photos of her mother, grandmother and grandfather. She had never opened it before, never even thought that maybe, there was a cassette left in there. Seeing the strange symbols written on the label of the cassette, the woman locked the cassette in a drawer in the study, worried that it's contents might negatively affect her daughter. The Walkman itself, she placed back on the self before joining her daughter in the living room.
Across the city, lightning danced around the spire of a skyscraper; the air heavy, motionless. In the basement, an eldritch being rose out of a complex diagram, rage smouldering in its eyes.
