The ambient light in the living room seemed to thicken and sink, the television's glow dying to a faint ember as six distinct shadows converged. Nightmare's form dripped occasional black beads onto the carpet. Error's outline flickered with digital corruption. Killer, Dust, Horror, and Cross completed the circle, their advance slow and deliberate. The sharp edges of their usual malice had softened into something more vulnerable—flushed cheekbones, jaws clenched tight, eyes locked on you with a feverish intensity. From each of them, a soft, rhythmic luminescence pulsed behind the fabric of their pants, painting the tense air with an eerie, bioluminescent light. They had you surrounded, the silence between you humming with a thousand unspoken things.
