so a living person cannot co-exist with their digital copy. Nevertheless, this doesn't prevent multiple digital versions from being simultaneously active. Law prohibits more than one active copy of a brain emulation or a strong artificial intelligence at a time (security backups being considered inactive), and the RPG delves into the possible abuses of this (like cult leaders implanting a copies of their own minds in every cult followers' neural interfaces). The RPG Eclipse Phase takes place in a frightening future after a technological singularity in which a group of superintelligent Seed AIs known as TITANs that were infected by an alien nano-virus forcibly destructively uploaded most humans and transhumans alive at the time and kidnapped their egos (term used for brain emulations in the setting), while destroying the surface in an event called "The Fall". Most of the survivors live in space, and have uploaded their personalities (or "egos") and can regularly switch between physical bodies ("morphs"), or inhabit simulated bodies ("infomorphs") in virtual environments. Duplication of uploaded personalities is also possible ("forking").
