Welcome to the land of Britannia, a picturesque country ruled by the benevolent King Lyonnesse. Or at least it was, until the king's guard assassinated him and started a full-blown Holy War!

Wrongly framed and sent into exile, they're now the princess's only hope to free the kingdom from the grip of the villainous Holy Knights!
