In Dayan, Kyushu, there is an ancient prophecy circulating:
"If the emperor's heart does not die, the mountains and rivers will never be destroyed."
After the founding emperor died, his soul was sealed into the "Candle Shadow Stone" - a sacred stone that can reflect life and death. The imperial mausoleums of later generations all used this stone as the foundation of the country. If the candle shadow stone is destroyed, the fate of the country will decline; if someone takes it, the soul can be changed and live forever.
