The world has two sides, one is light and the other is dark.
Ordinary people live above the surface world and spend their lives in an ordinary way.
But there are also some people who mistakenly enter the other world for various reasons. Although their memories will be erased, the technology is not perfect after all, and fantasy literature was born in the world.
The story unfolds as a result. It is the source of everything, a legend spread from the other world:
It is said that in a certain corner of the world, there is a mysterious gem. It produces a red glow when illuminated by moonlight, which is a gem set in a large gemstone. Drinking this drop of gem liquid can give people eternal life, and its name is Pandora.
People who believe in this legend do not know that there is another person who lives with Pandora.
That is the gem that can hold Pandora, and it also has an extraordinary name, its name is "Pandora's Box".
Legend has it that once the magic box is opened, various evil spirits proficient in the power of chaos will be released to harm the world.
Thousands of years ago, Pandora's Box was opened by a man seeking eternal life, and he indeed gained eternal life under the moonlight.
But when he woke up from the joy of eternal life, he found that the moment he opened the magic box, the world was filled with various evil spirits released from the magic box.
He gained eternal life and lost everything. In the end, he chose to sacrifice the drop of gem fluid in his body to restore stability to the world.
Although the myth has long been incomplete with the passage of time, later generations still refer to "Pandora's Box" as a disaster, a nightmare that is engraved in the human genetic chain.
Concept: Hope and despair complement each other. Only when there is hope can there be despair, and only when despair can give rise to hope.
