Welcome to the land of moonlight and eternal night.
The name of that land is Hourai.
A vast island nation surrounded by sea and mountains.
Hourai is also known as the "Land of Eternal Night" or the "Land of Moon-Flowers," and as the names suggest, it remains in perpetual night.
The seasons do not turn, and there is no spring, summer, autumn, or winter.
The most striking feature of Hourai is that the Queen of the Night flowers, which bloom eternally without withering, grow in wild profusion throughout the country.
This is the origin of Hourai's other name, the "Land of Moon-Flowers."
In Hourai, the Queen of the Night is the national flower.
Furthermore, the national emblem of Hourai consists of three crescent moons and the Queen of the Night flower.
