A mythic artifact known as the Crystal Consciousness cycles toward awareness... and with its waking, the entire psionic paradigm hangs in the balance. Many seek to control the Crystal: a psionic lich, a band of fanatic arcantists, and a guild powerful in the arts of the mind. Some would use the Crystal to dictate the future of psionics, while others would use it to crush the mental arts forever. Will you harness the Crystal's power to safeguard the Six Disciplines - or create your own new discipline and doom another? In this companion piece to the popular Psionics Handbook, player characters find themselves caught up a world-shaking event. In addition, fully one-third of this accessory/adventure details all-new rules from Bruce Cordell, the designer who brought you the official psionics cap system.
