Cygillan Ocean

Cygillan Ocean is a body of water in the world of Eos in Final Fantasy XV. It is the ocean south of the continent of Lucis, and Accordo Protectorate exists as a series of islands within it. The sea god Bismarck is said to dwell in its depths. The ocean is ripe with fish.

In the original version, the player crosses the ocean on the royal vessel at the start of Chapter 9. The ocean-cross is an in-game cut scene, during which the party will converse about what is going on in the rest of the world. In the Windows and Royal Editions, Cid Sophiar gifts Prince Noctis the key to the royal vessel as they arrive in Altissia, and the player can take the boat out to a cruise after talking to Weskham Armaugh at the Maagho. The player can manually steer the ship and dock at Altissia, Cape Caem and Galdin Quay. They can fish from the vessel, look for Bismarck, and take photos.
