In the extreme north of the continent of Etris, a gray wall stretches across, and twelve beacon towers stand in sequence, like a chain of light that can be broken at any time, blocking the old gods and the gray tide.
The first stage was launched on the sun, guarded by the sun god's envoy. She is an orphan of the dragon clan. She is proud and forbearing. Her hometown was taken away by the gray mist, so she can only burn her obsession to regain the dragon clan's territory into the sunfire.
The twelfth moon landing platform is guarded by the moon god. She comes from a famous family, is smart and cool, and always sees everything clearly outside the crowd.
There are also divine messengers on other stations - Hestia guards the morning fire, Athena holds the eagle's eyes, Zeus holds the thunder, and Hades guards the underworld.
One platform is a life, if one is lost, the darkness will be an inch thicker; all twelve towers will be destroyed, and the old gods will return to the world.
As for the sun and the moon, one is in the east and the other is in the west, separated by the entire northern border. In their first life, they were tablemates and walked into the crowd side by side. However, because of an unintentional word and a distance, one retreated first and the other walked toward someone else. When he died on the sunrise stage, he couldn't explain it clearly.
Intention: Gods and old gods, humans and remnants are not entirely right, nor are they entirely wrong. The real enemies are never each other, but the past that no one wants to look back on.
