The immemorials

“You are an immemorial. Following the accident at the Nostraphen laboratory on July 8, 2012, you lost your ability to retain memories. Every time you enter REM sleep, your brain destroys the information stored during your waking hours. Your last memory dates back to the day of the accident. “

It is with this unsettling message that the 30,000 immemorials living in the institute run by Nostraphen have been waking up for the past ten years. Every day, they must undergo tests aimed at developing a cure for their condition. But in reality, Nostraphen is searching for a truth serum and using the immemorials as guinea pigs.

A few resistant researchers, including Emma Lande, have secretly developed a treatment that they decide to administer to four immemorials chosen for their strong personalities: Ren, Maéna, Colette, and Daniel.
