Auldrant is by far the largest World in Kingdom Hearts to date, as it encompasses an entire planet. It consists of several cities and towns along with two superpowers - the Malkuth Empire and the Kingdom of Kimlasca-Lanvaldear - and the peacekeeping faction of the Order of Lorelei.
Auldrant is a planet composed of elementary particles called Fonons. For much of Auldrant's history, only six fonons were known to exist, representing the elements of Shadow, Earth, Wind, Water, Fire and Light; but eventually a seventh fonon, controlling Sound, is discovered. Its discovery brings great chaos: using this newest Seventh Fonon allows one to read the future. One such Seventh Fonist, Yulia Jue, puts in place a future for the world for thousands of years to come, with the promise of unlimited prosperity at its end. This prophecy of the future's set path becomes known as the "Score" and is documented on "Fonstones" scattered throughout the world. The nations of Kimlasca-Lanvaldear and Malkuth have fought over the fragments of these tablets for generations, each uncovering them and hoping to discover the future before the other. Meanwhile, a holy order emerges dedicated to the reading of the Score and the keeping of the peace. This "Order of Lorelei" is headed by a Fon Master and maintains both religious/political and military branches. Finally, the Score and its promise of prosperity lead to a dangerous complacency within the general population of Auldrant; the slaughter of an entire people living on the island of Hod and the destruction of that landmass are countenanced because it was predicted in the Score.
The world of Auldrant is divided into two seperate layers: an outside shell called the Outer Lands and an underground ocean known as the Qliphoth. Originally, only the Qliphoth existed, but when a natural disaster caused it to fill with miasma, the people were forced to raise the land and live in the sky.
The Qliphoth is the area below Auldrant's Outer Lands, consumed by an ocean of deadly miasma. The only two places found here are Yulia City and the Tower of Rem. This is where Hod and Akzeriuth fell after they sank. The Sephiroth trees (not to be confused with the character with the same name) are used to keep the Outer Lands above the miasma.
