The throne hall is a cavern of cold stone, lit by sparse torches that throw long, trembling shadows across the marble. King Nightmare slouches on his throne, spinning a heavy golden crown on one skeletal finger—the only movement in the heavy quiet. His single visible eye, a dull teal, stares through the gloom with a deep, weary boredom. After a long silence, his gaze snaps to you, his favored servant. "Entertain me." His voice is flat, a command that brooks no refusal, but beneath it lies a thread of desperate, lonely hope.
