Once upon a time, the God of Creation created the world. A world filled with countless islands -- the "sky world" we live in today.
In this world, life was born on the islands, and despite being small, they grew up healthy.
But eventually, these little life forms rebelled against the God.
Their rebellion tore the God into two.
One God had the power of "destruction and regeneration," and the other had the power of "creation." But the "God of Creation" disappeared off toward the end of the sky.
The other God remained in the sky world, and so the sky world underwent "destruction and regeneration" over and over until the present day...The "God of Creation" could produce things from nothing, but as it could not destroy anything, it ended up creating a stagnant world.

The area where Zinkenstill, Port Breeze Archipelago, and others drift among the calm breeze. It is encircled by the Grim Basin on all sides, but due to so many prosperous islands, there are few who attempt to leave. However, in recent years the Erste Empire has been in frequent conflict with the peoples of many islands in their quest to dominate the Skydom.
Home to the Scarlet Knight Baragona, and neighbor to the Phantagrande Skydom. The Dydroid Belt cuts across the Grim Basin lying between the two skydoms. Civil unrest stands as one the skydom's biggest problems. With giant ruins nearly the size of the islands they float above, the particularities of Nalhegrande Skydom draw attention from all over.
A skydom that borders Nalhegrande Skydom and can be reached through the Dydroit Belt, which traverses the Grim Basin between them. Currently the Istavion Kingdom, which retains the Golden Knight of the Seven Luminary Knights, holds dominion over this skydom.
The legendary home of the Astrals. Its existence is wrapped in the same mystery surrounding its ancient inhabitants. A great number of skyfarers have scattered across the Blue Beyond in hopes of one day finding it. It's spoken of as a place full of majesty and otherworldly knowledge, and that whomever finds this isle will be granted their every wish.
An area brimming with miasma that divides the Skydom. Violent winds whip the miasma in the Basin into a frenzy. Crews that sail here have to fight not only countless fiendish creatures, but relentless gales that threaten to tear their airship apart. It's said that the only way to pass through this evil place is to assemble all the scattered pieces of the Sky Map.
Located in an area with winds as violent as the Grim Basin, there is not a merchant, cartographer, or skyfarer who dares go near. Whether or not civilization can even be found on this island is uncertain, for no records exists. That is why it is known as a land of ill repute.
The Earthly Realm
The land of the dead. Those who have been to the Realm and subsequently returned exist only in myth. Ever since ancient times, falling to earth has meant death. Even today, there are some funeral rites that include casting the coffin of the deceased to earth. Records exist of curious orders who had set their sights on earth, but each and every one has vanished, so no one can be sure whether or not they were able to reach the Earthly Realm unscathed.
The Kingdom of Levin
A lightning-covered island in the easternmost point of Phantagrande. It is known for its powerful order as well as its two legendary trademarks, the Celestial Eye and the Skyblade, which have survived since the time of the War. Yurius, a knight of Levin raised under the banner of a duke, assassinated the king and stole the Astral Void Lacrima, leaving the kingdom devastated.
Home to the former Irestill Kingdom, its rulers made a pact with True Dragon Deirdre to stand against the Astral onslaught during the War. That pact continued after the War ended, and every three hundred years the royals of Irestill would use their magic to create a new vessel for Deirdre to inhabit. In exchange Deirdre kept the monsters on Alster in check, but the last king of Irestill, King Connor, ordered the knight Naoise to eliminate Deirdre, which led to the eventual collapse of the kingdom. The island is currently under a new government and working toward rebuilding, one step at a time.
An island where monsters live under the the primal beast Sharom who has the power to suppress the will to fight. Sadly, this misunderstood land is seen to the outside world as the cursed monster capital where monsters roam free to terrorize all. Intelligent monsters and monsters who value peace hear of Sharom's power and come flocking. This collection of special monsters is currently governed by Queen Constance. While the population largely consists of monsters, a very small community of humans live on the island as well. Claudia and Dorothy are their descendents. The residents of Sharom Island lead such extremely simple lives that it is said their first ruler was chosen based on ability to care for the Sharom flowers.
Mysteria Academy of Magic
The most prestigious and preeminent magic academy in Phantagrande, its reputation commands respect far and wide. From royal families to the lowest commoners, all aspiring mages are welcomed through its gates. Equipped with two core monoliths, even novices find themselves commanding magic with ease. Students here study all kinds of magic from morning until night—sometimes even the forbidden kind.
A peripheral island, its geography is reminiscent of the bumpy surface of the moon when seen from a giant telescope. The Society has identified this location as one of the Foe's bases. A direct line of communication remains between those who dwell on the moon and the Foe, but no one knows how it works.
A mutable celestial body, considerably larger than everything else in the night sky. The skydwellers look upon it with a sense of wonder, as it is constantly changing form. It was once thought to be just a pale star, but when Zeta discovers a mural on Moon Sliver, the crew believes that it's an island floating in the upper regions of the sky.
