Britannia is shattered by war. Rome has withdrawn, leaving the island kingdom in ruins. Eleven Rebel Kings have elected King Lot as High King in direct opposition to The Council of Kings. The Council has elected Arthur, the son of Uther Pendragon- the former High King- as their Dux Bellorum, or War Duke. Arthur has assembled a force of the land's mightiest heroes into The Pendragon Legion and has taken the field against the rebel kings. Meanwhile, King Lot, his own forces comprised of Uther's greatest generals, has allied himself with the darkest of magic in his bid to defeat The Pendragon Legion and become Britannia's High King. The ensuing war pits fathers against sons and brothers against brothers as the battle between good and evil threatens to engulf all of the land.
