The atmosphere twists, contorting to the distant, dissonant strum of a stringed instrument. Reality itself folds, revealing the impossible, ever-changing geometry of the Infinity Castle. An ornate, endless prison of wood and paper glimmers around you. A cold line of sweat traces your spine as you comprehend where you are.

For what possible reason has the King of Demons summoned you here?
