The year is 632 AD.
The Byzantine Empire is all that remains of what once was the mighty Roman empire. The Empire has only just survived a mighty war against Persia.
Both empires now lay exhausted from their long years of struggle. Meanwhile, further south in the deserts of Arabia, the prophet Mohammed has given new meaning to an old religion and sets the peoples of that land on a course of action which will echo down the ages.
Under the leadership of a succession of caliphs the Islamic arabs are about to descend on the prostrate bodies of the Persian and Byzantine empires.
