The planet of C53 Solar is on the brink of self-destruction, another planetary victim to insatiable thirst for power, greed, and total disregard for fellow life-forms. Billions of lives are at stake, and the answer may just lie within the great Silverdome of Rool. Two young scientists set off from the galactic ruling planets of Vactron. Their quest, to acquire the crystal domes that carry the key to changing the fate of the doomed planet, and their journey takes them to the deepest and most inhospitable of all the villain quadrants, to the Devil's Stone, where they find out that the keys come with a price . . . a very heavy price.
