God created the world, but there is more than one world. Human beings take the spotlight and think that the world belongs to them. Human beings exist in one dimension, and special species exist in another dimension. Two worlds exist in parallel. There is a relative balance between the two. Humans don't know the other world, but the other world doesn't know humans either?
Arcadia is a world that is opposite but similar to the human world. There are no inherent human rules here. This is a paradise and a purgatory. A purgatory for the weak. Arcadia, named after ancient Greece, arkadia, ark means to avoid, and adia is the king of hell. Arcadia means to avoid disaster, and it also extends to the paradise. During the Greek War of Independence from 1821 to 1829, Arcadia became the main battlefield. The war made the people miserable. The once paradise became a purgatory. People found that there was such a sentence engraved on a stone tablet: "Et in Arcadia" Ego' [I am also in Arcadia] People say this is what Death said.
"Coming to Arcadia was not my original wish, but it became my destiny. I thought I was strong enough, and I thought the pleasure of revenge was my only desire. However, after all, I could not live alone. He was snatched from the hands of the God of Death. It was a very different encounter, the same blood feud. He brought me to the light, but pushed me into the abyss." - Zhongli
"I have had an unfortunate experience, and she is God's compensation for me. I don't allow anyone to covet her. I would rather she wither by my side than flourish elsewhere." - Theodore
