Belisarius Saga

In Northern India, the Malwa have created an empire of unexampled evil. Guided or possessed by an intelligence from beyond time, with new weapons, old treachery, and an implacable will to power, the Malwa will sweep over the whole Earth. Only three things stand between the Malwa and their plan of eternal domination: the empire of Rome in the East, Byzantium; a crystal with vision; and a man named Belisarius, the greatest commander Earth has ever known....

The Malwa Empire has conquered 6th century India and is forging the subcontinent's vast population into an invincible weapon of tyranny. Belisarius, the finest general of his age, must save the world. Guided by visions from a future that may never be, he and a band of comrades penetrate the Malwa heartland, seeking the core of the enemy's power. And when Belisarius leads the forces of good, only a fool would side with evil. 

The Malwa Empire squats like a toad across 6th century India, commanded by ruthless men with depraved appetites. The thing from the distant future that commands them is far worse. Those who oppose the purulent hell the Malwa will make of Earth have sent a crystal, Aide, to halt their advance. Aide holds all human knowledge - but he cannot act by himself. Count Belisarius, the greatest general of the age and perhaps of all ages, must outwit the evil empire - and then, when there is no longer room to maneuver, to meet it sword-edge to sword-edge, because evil cannot be allowed to rule men!

Aide, a human soul embodied in a jewel, journeys back in time to join forces with Belisarius, the greatest general of the sixth century, to stop Link, an evil supercomputer that is using its vast powers to rewrite history to create the powerful, technologically advanced Malwa Empire. 

Armed with lancers, breech-loading rifles, steamships, and galleys, General Belisarius, accompanied by his own ally from the future, ventures into the Malwa Empire, a sixth-century kingdom ruled by Link, a horrifying and evil entity from the future.

Steamboats that launch Greek fire; telegraph lines connecting the battlefront on the Indus to ancient Constantinople, Byzantine palace plots aided by wireless devices: General Belasarius and his battle-hardened troops must advance quickly through the history of technology to stave off a coming age of ultimate darkness. And now - the epic final battle that will either give birth to or destroy Aide, Belasarius' doughty crystalline advisor and humanity's loyal friend!
