the Stone Vigil (Hard)

Too long has the Stone Vigil been ravished by the Dravanians and their thralls; too long has House Durendaire suffered this infamy. Time has come for its dragoons to retake the fortress, ten hundred lances and a thousand dreams of vengeance strong. Though the knights of Ishgard breach the gate to find a lodgment within the Vigil, the enemy is well defended and amply supplied. This deadlock must be broken─and who better than those who once made free of the fortress under the dragons' very noses, and lived to tell the tale?
