In the Interstellar Federation in 2342, human beings have footprints all over the galaxy, but at the end of technology, there are unspeakable taboos lurking.
Kyle Vance, the most "old-school" detective of the Federal Security Service, a "pure human" who refuses any prosthetic transformation, is sent to the remote mining star "Tartarus-7" to investigate an impossible secret room murder case. The deceased was a top scientist from the giant enterprise "Omniscient Group". He died of vacuum exposure in a completely enclosed laboratory, but the laboratory itself was intact.
The only clues at the scene were the two words flashing on the terminal: "They are echoing."
As the investigation deepens, Kyle is involved in a huge conspiracy that spans decades and involves the forbidden technology "soul weaving". The looming digital ghost, the mysterious assassin organization, and the tragic past about his deceased wife that was buried deep in his memory... All clues point to a terrible truth that can subvert human civilization.
In this era ruled by data and codes, the only thing he can trust is his own brain and his heart that has not been eroded by machinery. He must travel through the abyss of technology and face those "echoes" that should not be awakened, otherwise, the entire interstellar federation will be buried with it.
