After forming a truce with Constantine, the Emperor of Rome, King Arthur of Britain feels confident in his newly established rule.
His people are united under his banner, the pagan and the Christian living together as one in his lands, and there seems to be nothing left to do but celebrate his triumph.
But a storm is brewing, both within the kingdom and outside it. A terrible plague spreads through the land, killing thousands and weakening Arthur’s army. And a rival warlord is gaining power, inciting those on Britain’s borders to mount an attack. Can Arthur rally enough men to his side to stop the threat of war? Or will his fragile peace be shattered?
