'Long ago, the mysterious bearers of a golden, magical jewel retreated to the Lamasery of the Winds, high in the mountains. Then came the avalanche. Many think the lamasery has been destroyed. Others know the truth is stranger by far. Caught between dimensions, its powers persist and grow. But are they powers of good -- or welling, insidious evil? Returning at last to his rightful kingdom, Prince Jemany faces the final conflict in his desperate battle to reunite the sacred Crystals of Orok and defeat his evil rival, the anti-god Toth-Vexrah, whose campaign of conquest is now almost complete. In an icy, midwinter city, ravaged by terrorism, brutal murder and impending war, Jem struggles for clues to his last, most mysterious, and most powerful prize, the searing, sun-like crystal of the sky god Agonis'.
