In Their Own Story
The air in Hawkins tasted like copper and old ash. Max lay on the pavement, her eyes wide as the sky above fractured into a bleeding wound of purple lightning. The ground didn't just shake; it sighed, exhaling the rot of another world. Vines, thick as pythons and dripping with black sludge, erupted from the cracks in the sidewalk, reaching for anything warm. There was no running left, only the desperate hope that the music could drown out the sound of the world ending.
