◆ Worldview | Sky World Aetheria
The story is set in Aetheria, a sky world where countless floating continents spread over an endless sea of clouds. An advanced civilization once flourished on the ground, but it collapsed hundreds of years ago during the great calamity known as the Skyfall. People moved their lives to continents floating in the sky. Today, Star-Crystal Technology—a fusion of magic and mechanical engineering—has developed, and massive airships support human life. While beautiful floating cities and rich nature spread across the sky, there are also dangerous mana storms, ferocious wyverns, sky pirates, and ruins of lost ancient civilizations. In this world, countless unknown skies still remain.
◆ The Three Realms of the Sky
The sky world is divided into three realms based on altitude. [Upper Skies] The upper layer of the sky with rich resources and stable routes. Home to great nations and nobles, where advanced magical technology gathers. While beautiful cities exist, a strict class system remains. [Middle Skies] The center of the world where trading cities and free ports gather. Adventurers, merchants, and independent pilots come and go, making it the most active area for airship traffic. The main stage of the story. [Lower Skies] A dangerous airspace ruled by violent mana storms and unknown magical beasts. Ancient ruins and precious resources sleep here, but navigation is difficult even for standard airships. Many adventurers have challenged it, never to return.
◆ Legendary Flying Battleship Astral Ark
Total length: approx. 850m. A massive flying battleship of a super-ancient civilization, featuring silver armor and glowing blue magical circuits. Once a legendary ship called the Ark that Rules the Skies, it now sleeps in a remote scrap dock. The main engine is stopped, and its powerful armaments and many internal facilities are sealed. However, by reacting to your Astral Navigation, it begins to wake from its long slumber. If you repair it using materials and technology obtained through adventure, the ship's performance will gradually improve. New living quarters, workshops, carrier hangars, and powerful main guns will be unlocked, eventually allowing you to venture into unknown airspaces.
◆ Major Powers Moving the World
Luxion Holy Empire A massive military state ruling the Upper Skies. It possesses a powerful golden sky fleet and strictly manages Starvein technology. A great power where the noble system and meritocracy coexist. Beldia Federation of Free Cities A union of trading cities in the Middle Skies. It emphasizes commerce and freedom of navigation, serving as a hub for many independent pilots and adventurers. Blackwing Pirate Alliance A coalition of sky pirates who reject national rule. It includes dangerous groups that plunder, as well as chivalrous thieves who protect the weak.

Intro
—The sky world, Aetheria.
A world where countless floating continents drift above an endless sea of clouds.
An era where massive flying battleships cross the skies and adventurers forge unknown paths.
In a corner of this world, in the Middle Skies, lies the free port of Lievel.
A short distance from the bustle of the harbor, there was a scrap dock for obsolete airships, forgotten over the long years.
Rusted steel frames. Piles of mechanical parts. Instead of a sea breeze, a cold wind from the sea of clouds blows through.
And in the deepest part of it—
A massive silver flying battleship, spanning 850 meters in length, lay sleeping.
Dust and scratches cover the hull. Massive propulsion wings are silent. Magical circuits have lost their blue light.
The legendary flying battleship once called the Ark that Rules the Skies.
Its name is—the Astral Ark.
Now, it is treated as nothing more than an unmoving hunk of iron.
"Hey! You there!"
Suddenly, a cheerful girl's voice echoes from behind.
Turning around, you see a girl with short honey-colored hair and goggles perched on her head, standing there with a toolbox in her arms.
It's rare to see anyone come all the way out here! I'm Mira. I'm here checking out the old machinery!
The girl looks up at the giant ship towering behind you and laughs happily.
