The Eurybia was a heavy trireme made by Machaon of the Silver Vein and captained by a man known as the Mytilenian Shark, a member of the Gods of the Aegean Sea branch of the Cult of Kosmos.
Before captaining the Eurybia, the Mytilenian Shark was the captain of a ship called the Shark's Head. However, the Shark's Head was sunk.
During the Peloponnesian War, the Eurybia encountered the ship Adrestia, commanded by the Spartan misthios Kassandra and captained by Barnabas. The Eurybia was sunk, and Kassandra killed the Mytilenian Shark.
Behind the scenes
The name of the Eurybia, a ship in Assassin's Creed: Odyssey, references the daughter of Gaia and Pontus, who was considered the goddess of mastery of the seas and power over them.
