Lord of all waters, revered by the ocean-dwelling Sahagin.
Lurking in the lightless depths, Leviathan devours all that crosses his path. In ages past, seafaring folk believed that tidal waves were a sign of the great serpent's wrath, and they sought to appease him with living sacrifices.Official website
Leviathan is the primal of the Sahagin beastmen tribe, and a boss in Final Fantasy XIV. He appears in the Main Scenario, and as a superboss in an optional "extreme" battle. Though he is mentioned a few times throughout the Main Scenario, and his servants play a big role in Limsa Lominsa's opening storyline, Leviathan himself doesn't appear until the events of "Through the Maelstrom".
Leviathan is the patron of the Sahagin, and has a number of pirate followers known as Serpent Reavers in his service. Those tempered to his will are known as "drowned". The Serpent Reavers resorted to raiding Ul'dahn caravans of crystal shipments—aided by a few corrupt Brass Blades—to supply the Sahagin with sufficient crystals to summon the Lord of the Whorl. He is spotted within the Sapsa Spawning Grounds, and soon makes short work of a diversionary Maelstrom fleet.

As he heads to open sea, Admiral Merlwyb Bloefhiswyn realizes Leviathan is trying to summon a tidal wave to strike Vylbrand. To confront the primal they'd need a ship outfitted with corrupted crystals to weaken his dominance at sea. Storm Marshall Eynzahr Slafyrsyn notes they'd need at least two ships worth of crystals to approach the primal, and recalls a tale of how the pirate Mistbeard once tethered two ships to carry a large plunder. Using the same tactic, a make-shift barge called the Whorleater is assembled in Moraby Drydocks, enabling a platform so Warriors of Light may confront the dread Leviathan at sea.
Leviathan does not stay down for long, as the Sahagin resummon him. Faced with an even more powerful Lord of the Whorl, Storm Marshal Slafyrsyn prepares the Whorleater once more—and, once more, the adventurer defeats the primal.
Leviathan is fought as a boss twice times at The Whorleater: first in the Through the Maelstrom arc of the Main Scenario, then in an optional Extreme battle. Both are fought at level 50 with a full party of eight.
Completing The Whorleater (Extreme) is optional, and grants the achievement "I Eat Whorls for Breakfast".
Leviathan appears as an Aqua-elemental card.
Leviathan appears on a Triple Triad card in the version playable via Final Fantasy Portal App.
Behind the scenes
Leviathan was originally meant to appear as a boss in the 1.0 version, but was cancelled as the fight was scheduled to release in the aftermath of the 2011 Tōhoku earthquake and tsunami and was considered disrespectful to those affected by the event.
Square Enix's Eorzea Cafe served a dish called "Leviathan's cold blue noodle" whose description translated to: A dish inspired by the Water God, Leviathan. The blue soup reminiscent of a raging Rhotano Sea, and the rich flavors conjured up by the abundant array of fresh seafood will hit you like a Tsunami!
Leviathan (Biblical Hebrew לִוְיָתָן or לווייתן Liwyāthān) is a violent sea creature referred to in the Hebrew Bible as well as the Talmud and some other ancient Jewish texts. During the golden age of seafaring, the term Leviathan became synonymous with any large sea creature, sometimes describing whales. Bible scholars interpreted Leviathan to be either a demonic sea creature and an enemy of God.
The Talmud and other ancient Jewish sources refer to Leviathan more specifically as a sea serpent, sometimes with multiple heads capable of breathing fire, that was made on the fifth day of Creation. It is said that during the end of days, God will make tents, or sukkah, out of the skin of Leviathan for the righteous to live in. Some have speculated that Leviathan was based on a real animal, the most popular theory being the Kronosaurus and the Nile crocodile.
In the Final Fantasy series, Leviathan is sometimes referred to as the King of the Seas. Its incarnation in the series appears to derive from the legends of the Shinto god Ryūjin or Owatatsumi, said to be the dragon god that reigns over the seas. It also resembles the Chinese dragon, mystical beings seen as the rulers of moving bodies of water, and the Dragon God as the dispenser of rain.
