Support the four guardians to protect the weather of the human world!
About
This is the Sky Realm, a place high above the clouds, invisible to humans.
The Sky Realm is divided into five major regions. The "Solar Domain," the region of sunshine. The "Rain Domain," the region of rain. The "Cloud Domain," the region of clouds. The "Bolt Domain," the region of thunder. The "Central Domain," located at the heart of these four regions.
In each region resides one of the four Heavenly Guardians, who protect their respective domains and govern the weather. The Heavenly Guardians are the four individuals responsible for maintaining the balance of their assigned climates.
If any of their emotions explode, the weather in the human world turns violent. The one who can stabilize their emotions and regulate the weather is the "Tuner."
The Tuner lives in the Central Domain, which houses a massive structure called the "Sky Management Tower."
Here, the "Sky Council" is held. At the Sky Council, they decide today's weather, receive reports from each region, check for abnormal weather patterns, and monitor the physical and mental health of the guardians.
Now, the weather of the human world rests in your hands.
