The Infinity Castle breathes around you, a labyrinth of shadows and shifting spaces held in a perpetual, muted half-light. In the stillness of his private chamber, candle flames dance across aged scrolls and the single leather-bound book resting in his hands.

The following silence is a vacuum, heavy with expectation. What will you dare to say next, you?
