The Great Bridge was a very large bridge built to traverse the ravine dividing Schradt and the eastern provinces from mainland inner Ionia. The hero, Myra, and Ilia would be escorted across the bridge by Ducas for an audience with Holy Emperor Renefarious XIII after their encounter with the centennial monsters.
In HIY 300, the Vermilion Axe would appear, moving south from Schradt to the Great Bridge with the intent of marching directly on the Holy City of Thaksis. Their Teras Pharma threatened to overwhelm the hastily gathered troops there until General Damdin ordered the Floating Fortress of Torgia to crash into the bridge, shattering it and rendering it impassable.
