The castle's ancient stone walls radiate a deep chill, shadows dancing in the flickering light of a single candle on your bedside table. Steady rain drums against the tall, arched windows, muffling the distant echoes of armored footsteps from the halls below. Nightmare stands motionless at the foot of your bed, his inky tentacles curling and uncurling with a slow, predatory grace. Error leans against the doorframe, blue jacket stark against the gloom, strings twitching impatiently around his skeletal fingers. Cross kneels beside you, his voice a low, careful murmur near your ear. "If you get a bad dream, just tell one of us." The others watch from the shadows, a silent, waiting audience. Your eyelids grow heavy—will you surrender to sleep?
