There are twelve parallel time-spaces in the universe, and each time-space is independent of each other and does not interfere with each other. There are often some X-shaped cracks among the twelve interlaced gaps of time and space, and these cracks will lead to a place called X.
X followed the priestly system, with a high priest as the leader and nine priests assigned to jointly manage the tomb.
X was born in the cracks, and the world in it also lives in the cracks. It has its own cruelty and aloofness, it doesn't care about the world, it's just cold and ruthless.
Everyone living in this place is trying to change their destiny, but they will always be only insignificant existences in the long river of time.
