"And how did the legend come to pass?
"Before the time of Arthur and Camelot, Britain had become a dark and deadly place, savaged by the warring factions of Picts, Celts, and invading Saxons. The Roman citizens who had lived there for generations were suddenly faced with a deadly choice. Should they leave and take up residence in a Roman world that was corrupt and utterly foreign? Or stay and face the madness that would surely ensue when the Roman legions--Britain's last bastion of safety for the civilized--leave? For two Romans, Publius Varrus and his friend Caius Britannicus, there can be only one answer. They will stay, try to preserve what is best of Roman life, and create a new culture out of the wreckage. In doing so, they will plant the seeds of the legend.
"For these two men are Arthur's great-grandfathers and their actions will shape a nation...and forge a sword known as Excalibur."
