The first person is human, the second is a ghost, and the third is a god: one who endures countless calamities without perishing, survives through endless tribulations, and lives on air alone without dying. Such beings are called immortals and gods. Perhaps one day, all mysteries will become ordinary, all wonders will rot away into nothing, and all mighty powers will vanish. The gods will fall from their thrones, stripped of their power and memories, and descend into the mortal world. People call that day the Twilight of the Gods. And yet, there will always come a day when the gods return to their thrones, wearing brand-new faces.
