"Death is a promise, for each death holds the embryonic whisper of the next. We sink into the grave and witness a new evolution of self. What makes us human? What is lost in transformation? Questions such as these no longer server us. The sacred techniques have done away with death-as-an-end, so what remains? Beauty in the splatter, in the system's never-ending collapse."

Cryo Archive did not put the TCIV colonists to 'sleep'. Cryo sleep is equivalent to death. The process of revival is a rebirth. These 30,000 souls took place in an experiment that was never done on that scale before. Over 300 years later, it has never been reproduced again.
