Laroche was one of the founders of Mousillon, a man who's family dated back to the very settling of Bretonnia during the times of Gilles le Breton. Clad in shining armour, Laroche was a great knight, having repelled Orc invaders from his castle walls and winning the great Tourney of Couronne, claiming a magical silver helmet from the Fay Enchantress herself. When he set off to quest for The Grail, he drove forth the foul Beastmen from the hallowed woods of Lapelle and founded the great Grail Chapel of Mousillon, he spent a long solitary vigil upon the Grey Mountains during which the Lady of the Lake finally guided him to one of the Grail's resting places.
He became renowned as a shining example of the true Bretonnian knight. Records told of a man who was pure and holy, pious in every way, noble to his servants and his peers. His humility had been near-legendary in his time and his ultimate sacrifice, saving the Queen's life from a traitor's blade, had been a glorious end to a glorious life. Laroche was buried in a grand tomb, replete with tapestry's depicting his heroic deeds.
Centuries later, a young knight by the name of Tybalt recieved a vision from the blessed spirit of the Duke. A dreaded Necromancer was threatening the lands of Bretonnia, Laroche guided the young knight to the foul sorcerer's lair and bade him to take his ancient silver helm for protection. Indeed the Knight would have perished instantly under the Necromancers powers had it not been for Laroche's blessed helm, with this protection Tybalt was able to slay the Necromancer and save Bretonnia from his schemes. With this final heroic deed Laroche would return to defending the realm of Lileath as all Grail Knights were destined do do.
