Grasitha - The Final March

Described in the Enchiridion as one of the lost treasures of the See, Grasitha is said to have been created on the battlefield by Ser Branthuc the Meek during the final march of Thordan's Twelve. Having shattered his sword on the scales of a mighty drake, the knight reshaped the sundered blade into a spear using naught but the warhammer of a fallen companion and the pyre upon which his brothers burned (Encyclopedia Eorzea)
