The special nature of the Heavenly Fire Sea in the eastern part of the Moon Worship Region and the hot environment made it so that not many races could survive here.
Among the races that lived here, the Mirror Image Race and the Heavenly Mask Race were the main races.
The heavenly fire crystals from the Heavenly Fire Sea were one of the many commonly needed offerings designated by the Red Moon Shrine. Hence, they were often plundered by other races.
In order to resist external enemies, the two races had no choice but to join forces and form an alliance.
They even established this holy city.
This city had lasted for a thousand years and had experienced the heavenly fire crossing the sky time and time again, protecting countless members of the two races.
Although it faced destruction in the middle, it was rebuilt in the end. Hence, in the hearts of the two races, this city had a profound meaning.
