Nightmare Ocean, Blackbeard's territory.

At the center of this region was Blackbeard Island⁠—Blackbeard's base.

After the military parade and review, Ettoman's Invincible Steel Fleet had headed toward the Nightmare Ocean in a towering fashion.

At this time, Ettoman was the most powerful empire of the ocean. Relying solely on brute force, it wantonly eliminated the pirates in the Nightmare Ocean.

This Invincible Fleet's primary firepower was the new ironclads, of which there were more than thirty. This fleet defeated the combined forces of the five admirals under Blackbeard's command during an initial skirmish.

Three of Blackbeard's five trusted subordinates were killed in that battle. His favorite—Black Lasso, who was fond of skinning—was blown to bits by the huge cannons on the spot.
