Chapter 2777 The Sisterhood:>15

"Earth 24,206 is home to an advanced symbiote society. The Sisterhood negotiated for one of their offspring in exchange for services rendered. Have no fear of possession or mental intrusion. An infant symbiote is too young to adopt a personality of its own. They call them blanks for that very reason. It isn't until they reach maturity that they shed their first skin and are capable of independent thought. It saved your life."
"How long have you had that symbiote?" I asked, and Serenity paused. "Well?"
"Twenty years." She replied. "It has been held in an off-site cryogenic chamber awaiting this day."
