Long ago, the world fell into twilight, when the great empires of old consumed each other in sorcerous cataclysms. In the south, the Star Towers fell, swallowed by the sea, while the black glaciers descended upon the northern holdfasts, entombing the cities of Min-Ceruth in ice and sorcery. Then from the ancient empire of Menekar, the paladins of Ama came, putting every surviving sorcerer to the sword and cleansing their taint from the land. The pulse of magic slowed, fading like the heartbeat of a dying man. But after a thousand years, it has begun to quicken again. 

The ancient magic of wizards was anything but dark. It was the enlightenment that lifted humanity from the squalor of superstition, and the worship of fell spirits and capricious gods, but those days are gone. The shining glory of the sorcerers burned away the subtlety of wisdom, replacing it with easy power, held only in the hands of the elite - a new age built upon the elemental supremacy of aristocrats and the ignorance of the masses.

Minalan gave up a promising career as a professional warmage to live the quiet life of a village spellmonger in the remote mountain valley of Boval. It was a peaceful, beautiful little fief, far from the dangerous feudal petty squabbles of the Five Duchies, on the world of Callidore. There were cows. Lots of cows. And cheese. For six months things went well: He found a quaint little shop, he befriended the local lord, the village folk loved him, he found a sharp young apprentice to help out, and, best yet, he met a comely young widow with the prettiest eyes.

The nightwalkers have returned, creatures that roam the darkness searching for anyone foolish or unfortunate enough to find themselves without light to protect them. And the people of Entarna carry lanterns and torches, wielding them as shields against the night's creatures. But sooner or later all lights fade. All flames go out. Torrik and his wife were once soldiers in the war against the Dark. But when their son Alesh was born, they left that life behind them in the hopes of keeping him safe.

Gavin Guile is the Prism, the most powerful man in the world. He is high priest and emperor, a man whose power, wit, and charm are all that preserves a tenuous peace. But Prisms never last, and Guile knows exactly how long he has left to live: Five years to achieve five impossible goals. But when Guile discovers he has a son, born in a far kingdom after the war that put him in power, he must decide how much he's willing to pay to protect a secret that could tear his world apart.
