Nef

Nef was a human teenager living on Omega. She was killed by the Ardat-Yakshi Morinth, who seduced her and then killed her my melding with her.

During the mission Samara: The Ardat-Yakshi, Shepard and Samara can help Nef's mother in investigating her death. Her mother implores them for her help, claiming that no one on Omega seems to care that her daughter was murdered, and that she is desperate for help from whoever will aid her.

In the process of helping Nef's mother, they can search her room for evidence. In her room, they find that Nef was an artistically-talented teenaged girl who, though shy and reserved, possessed incredible creative ability.

Nef's mother informs Shepard and Samara that, all of a sudden, her daughter became infatuated with an Asari on Omega (Morinth, unbeknownst to the three at the time), despite her mother's warnings and worrying. She says that Nef spent entire nights out at the Afterlife Club. Nef sometimes did not return for days, and until news of Nef's death reached her mother, she had no way of knowing that her daughter had died.

The Asari enthralled Nef by appealing to her artistic and musical interests. Morinth also addicted her to Red Sand to make her more impressionable and prone to suggestion. Finally, when Nef was at her most vulnerable, Morinth joined minds with her, thus killing her.

If Commander Shepard helped Nef's mother, completed Samara's Loyalty mission, and chose to aid Samara in killing Morinth, he/she will receive a mail from her. Her mother states that even though her daughter is gone forever, and that what little Nef had was wrongfully taken from her, she is happy to see that she has been avenged, and that Morinth has paid for her crime.
