(Added the name of the song!)

Hey, hey, heeey!
It's knee-socks fan, and the creator of sounds within FFXIV (aka sound director), Masayoshi Soken here!

During the recent NicoNico Chokaigi 3, I revealed the fact that it was my voice that is singing the lyrics for the Leviathan battle song. I also showed a brief look into how the music comes together during the editing process, and I blew some minds when I played a bit of the female chorus version of the theme that we didn't use!

Ever since the release of Patch 2.2 players have been asking me for the Leviathan lyrics so I figured it'd be a good time to share them! (That way we can avoid any unintended interpretations...don't remind me of the Titan fan lyrics...)

"Through the Maelstrom"
---------------------------------
Leviathan Leviathan Endless!
Leviathan Leviathan Send us!
Leviathan Leviathan Breathless!
Leviathan Leviathan Deathless!

Leviathan Leviathan Restless!
Leviathan Leviathan Test us!
Leviathan Leviathan Tend us!
Leviathan Leviathan Mend us!

Drifting in the realm beyond all knowing
Forsaken, shedding tears of glass
Now tumbling from the boundless heavens, taken
White moondrops, burning indigo

Leviathan Leviathan Endless!
Leviathan Leviathan Send us!
Leviathan Leviathan Breathless!
Leviathan Leviathan Deathless!

Leviathan Leviathan Restless!
Leviathan Leviathan Test us!
Leviathan Leviathan Bend us!
Leviathan Leviathan Rend us!

Leviathan Leviathan Vengeance!
Leviathan Leviathan Penance!
Leviathan Leviathan Send us!
Leviathan Leviathan End us!

Silence from the knife that softly severs
Mistaken for an unsung prayer
Now rising from the soundless Deep. Awaken
White fury, blinding indigo

Swell ye seas of old, Leviathan Leviathan
Surging tides grow bold, Leviathan
Seething currents whorl, Leviathan Leviathan
To swallow up the world, Leviathan Leviathan
---------------------------------
Phew! And there you have it—Leviathan swallows up the whorl world! (Get it?)
