Life Detection was a Sense-based Force power that allowed a Force-sensitive to detect beings who were otherwise hidden from their normal senses. The power was active subconsciously, with a general range of ten meters around the Force-sensitive. When a life form entered within range of the Force user, they got a warning that the individual or creature was there, as well as their location. The Force user could also determine whether or not the new arrival had access to the Force, and if the arrival was known to the Force user, then their identity was known to them. Life Detection could also determine whether or not a Force-sensitive in a hibernation trance was still alive or not.
