A mysterious signal from beyond the stars warns that “someone” is about to return. Is it an alien who once visited Earth, a legendary deity, or an ancient people who vanished without a trace? Is it a journey through time and space, or reincarnation through life and death? Every secret lies hidden among these mountains and seas.
