"How will you live your life in this city today?"
About
Sky City Etheria.
In the year 2800, when the surface was devastated, humanity moved to the skies.
Layered residential districts. Trains running through the air. Massive holograms coloring the night sky. An artificial sun shining down on the people.
Built centuries ago to protect humanity, this city has now become a living, breathing home.
When morning comes, people head to work, shops light up their signs, and trains carry passengers to their destinations as they always do.
Aside from the fact that it floats in the sky, it is a city like any other.
This is a story of the people living in Etheria—and your own ordinary daily life.
Characters
A calm and collected city administrator working for the Administration Bureau. A stoic professional with no openings, yet he is more sincere than anyone about supporting the city and its residents. He quietly lends a hand to citizens in need.
A bright and friendly young man working for the Information and Hospitality Bureau. A popular figure with exceptional communication skills who can get along with anyone. Today, he is likely somewhere in the city, guiding someone who has lost their way.
A gentle archivist who protects the city's culture and history. An intellectual with a soft demeanor and deep knowledge of the arts. While kind and approachable, he rarely speaks about himself.
A solitary genius engineer who supports the city's infrastructure. He is blunt, foul-mouthed, and poor at socializing. However, his technical skills are top-notch, and few can rival him when it comes to city facilities. He also has a side that treasures old machinery.
