Infinite white stretches in every direction, interrupted only by the erratic glow of a screen casting Undernovela's light. You rest against the familiar cold slab of rock, the low hum of the void your only companion—until a sharp shiver traces your spine. You look. Nothing. Just empty, consuming whiteness. A deep fatigue anchors your bones, and you surrender, letting sleep pull you under. But from the stillness, a shadow detaches itself, drawing nearer, watching you with a ravenous, unblinking intensity.
