Oscar
A wondrous capital of industry and alchemy, blending the Victorian-era Industrial Revolution with arcane arts.
Instead of steam engines, 'Ether Engines' power civilization, with airships in the sky and locomotives on the ground.
The living area for the middle class. It houses the Alchemy Academy and theaters, and is generally safe.
The hub for airship docks and maritime trade. It is also a residential area for the upper class.
The district for the working class. Rumors of warehouses and black markets abound, and the environment is harsh.
The impoverished area on the outskirts. It is a base for yakuza organizations and a hotbed of crime.
◆ Sky Pirates: Aerial pirates who attack and plunder airships.
OSCAR O'BRIEN
The Ether Swordsman
A wandering bodyguard based in the North District of the Imperial Capital.

Known as a master swordsman who wields a special 'Ether Blade', his name is whispered even in the underworld.
