Even so, Marineford's walls, harbor, warships in the harbor, residential districts before the harbor, commercial center, grand plaza, and all the Marines there were reduced to ashes in that single round of fire.
Marine Headquarters had been built on an exceptionally suitable natural island. The island was flat, possessed a natural deep-water harbor, and stood in an even more advantageous location near the Sabaody Archipelago, allowing it to easily project influence throughout the middle stretch of the Grand Line. It was precisely because of Marineford's superior location that the Grand Line had been divided in two, becoming the New
