The Leviathan is a legendary creature that roams the Leviathan sea feeding on smaller creatures that roam into its territory.
The Leviathan sea is a massive crater that goes deep into the abyss of the ocean. The sea is located many feet below Numenoria. Many sailors who have gone into the leviathan sea have never come back.
It is said that the Leviathan was a race of underwater creatures created during the war of the Ancients that ravaged the planet many eons ago. Many of its kind were killed during the war leaving behind only one to roam the waters.
Even to this day the creature resides in the ocean feeding on any morsels of meat it can find in its territories.
