Martrud was the first Duke of Montfort and the ninth of the Grail Companions of Gilles le Breton during the Twelve Great Battles that freed and unified Bretonnia. A towering and mighty warrior and a champion of the common man, Martrud was beloved by those he protected. Wherever he fought the peasants redoubled their efforts and fight to the death rather than dishonour their lord.
Martrud was the lord of the Bretonni of Castle Montfort and the surrounding lands by 977 IC, when Gilles le Breton began his campaign to free the lands of Bretonnia.[1c] Though Castle Montfort has stood guard over the narrow passage through Axe Bite Pass for hundreds of years, it was Martrud who built its walls to the towering heights that they remain, and it is this image that is depicted today in the family's heraldry.
Lord Martrud joined the Grail Companions of Gilles when the knights of Bastonne, Mousillon, Lyonesse, Bordeleaux, Aquitaine, Brionne, Carcassonne, Quenelles and Parravon came to his aid during the sixth of the Twelve Great Battles. Together they managed to break the siege of the Night Goblins, and then followed a miraculously healed Gilles into the caves where they hid until they killed their kings and many other monsters, in what was known as the Seventh Great Battle.
After the securing of all the lands of the Bretonni tribes, a great meeting took place in the home of Folgar of Artois. Here, the formal dukedoms were created, and the Bretonnian calendar was introduced - thus, year 979 of the Imperial Calendar is considered year 1 of the Bretonnian one. Each of the great lords of the Bretonni, the fourteen Grail Companions, including Gilles le Breton, were named Dukes. The Dukes swore oaths of allegiance, and Bretonnia was formed.
