Morinth is the fugitive daughter of Samara. She is an Ardat-Yakshi, asari who are born with an inherited trait which kills their mates during sexual encounters by burning out their nervous systems. Morinth joins Shepard if she is assisted with trapping Samara so that Morinth can execute her. She will then disguise herself as her mother and takes her place in Shepard's plans squad, so that only Shepard knows of Samara's death. Shepard may choose to mate with Morinth, although it will result in his or her death. If the player imports a save game where Morinth is recruited and survives the events of "Mass Effect 2", she will appear in "Mass Effect 3" as an indoctrinated husk-like enemy type known as a banshee.
