How far can a hero fall? Far enough to lose his soul? Dhamon Grimwulf, once a Hero of the Heart, has sunk into a bitter life of crime and squalor. Now, as the great dragon overlords of the Fifth Age coldly plot to strengthen their rule and to destroy their enemies, he must somehow find the will to redeem himself. But perhaps it is too late. Downfall marks the return of Dhamon and other characters from author Jean Rabe's bestselling Dragons of a New Age trilogy.

The people of Krynn have known war in past ages. Some are still alive who remember the triumph of good at the conclusion of the War of the Lance. Still more remember the devastation of the Chaos War, which ended the Fourth Age of the world. But now a new war is about to begin, more terrible than any have known. This war is one for the very heart and soul of the world itself.

The Summer of Chaos has ended. Ansalon's nightmare has only just begun. The gods have departed the world, heralding a new Age of Mortals. But before the dust of war can settle, vast shadows cover the land. Dragons have come to Ansalon, larger and more powerful than any ever seen, and they will wreak havoc on nations still trembling from war. As the lands themselves begin to change under the dire magic of the new dragon overlords, new heroes arise to lead the fight for freedom.

When Destina Rosethorn and her companions were transported to a time centuries before their birth—to the days of the Third Dragon War—the Graygem of Gargath brought chaos to the battlefield and changed the course of history. Upon returning to the Inn of the Last Home, where their journey began, Destina’s party discovered a world completely changed. The forces of evil now hold sway over their land. The River of Time is rising, flowing inexorably toward the present day. Destina and her friends must make one last, desperate attempt to restore time’s river to its proper channel.

The companions believe they have slain the evil Dragon Highlord Verminaard. They have rescued the refugees from Pax Tharkas and taken them to a valley in the Kharolis mountains.
