One of the three childlike Drayans cared for by Tuvok on a sacred moon, who disappears overnight as her long life comes to its natural end.
Elani is a Drayan. She appears in the second-season Voyager episode Innocence.
She is found with Tressa and Corin by Tuvok after his shuttle goes down. The three look and behave like small children, terrified of being left alone in the dark, and Tuvok shelters them in the wreck while he tries to repair it.
The children believe that a monster takes people in the night, and Elani is among those who vanish. First Prelate Alcia later explains to Captain Janeway that Drayans are born old and grow younger; the moon is where they go to die, and the confusion of extreme age has made them forget why they came.
