An ocean spirit is a powerful being of the sea, otherwise known as a Caspeid. They are beings that were created by Lord Caspian to assist in the creation and the rule of the sea in the early days of the world. There are four Caspeids; Borak of the North, Sefyr of the West, Eusia of the East, and [Notia]] of the South. They rule different seas, and are loyal (to vastly different degrees) to Lord Neraeos.
