The Sa'ari mind shroud was a Force power that occurred naturally in members of the Sa'ari species. Due to their endemic sensitivity to the Force, individuals gradually adopted this type of mental barrier as a means of retaining their personal identity and protecting their privacy. One of the most heinous acts that a Sa'ari could perform was to force their way past another Sa'ari's mental shrouding without permission. Referred to as shroud-crime, such acts were capable of killing the victim, or at least causing severe emotional distress.
