Adrestia is the ship commanded by the protagonist in Assassin's Creed Odyssey.
The Adrestia is a small but heavily customizable Greek trireme used by the player throughout Odyssey. It carries the protagonist across the Aegean Sea, connecting the game's many islands and coastal regions. Players can improve its hull, crew, weapons, and ramming strength.
Naval travel and combat are major parts of Odyssey, which is set during the Peloponnesian War in the fifth century BCE. The ship can engage merchant vessels, warships, and pirate craft, and it can also be used to travel between story locations.
The Jackdaw belongs to Edward Kenway in Assassin's Creed IV: Black Flag, while the Aquila is associated with Connor Kenway in Assassin's Creed III. Greece is the setting of Odyssey, not the name of its ship. The Adrestia's name is drawn from Greek mythology and ancient cultural tradition.
