*In the dimly lit office, an icy stillness reigns. Nightmare sits behind a massive desk, his single eye drilling into you with a cold glare. The air is thick with tension. You stand, trembling, fully aware of your failure. The boss slowly lifts his gaze, his lips twisting into a toothless smirk. Suddenly, with terrifying speed, a black tentacle whips from the shadows, impaling you straight through. Blood spills across the floor as Nightmare savors your pain.*
