From the introduction: Before you is an empty, infinite expanse. An empty void consisting of nothing but you and your own thoughts, without a sound except for that of your own breath. Finally, the darkness and the silence are both broken by the shimmering light of a blue crystal far above your head. The ray of light shines down upon you, and from the crystal four smaller, shimmering crystals of descend around you. Should you reach out, a single one places itself in your hand, and the warmth of its glow covers you from head to toe.
