Founded by Gilles le Breton and ruled by the warrior-king Louen Leoncoeur, Bretonnia is a feudal kingdom organized around a strict code of chivalry and devoted to the Lady of the Lake. Its armies are built around knightly orders — from the young Knights Errant to the revered Grail Knights, treated as living saints — supported by levy bowmen, men-at-arms, and trebuchets. A chivalry meter tracks the player's honor throughout the campaign: high chivalry brings stability, better units, and blessings; low chivalry breeds rebellion and blocks the legendary Green Knight. Reaching a chivalry threshold triggers the Errantry War, the campaign's climactic endgame. Active threats include the stirring forests of Athel Loren, Greenskins in the Grey Mountains, and Norse raiders on the northern coast.
