Ennia was a member of the Sevateem, daughter of Sole and Neela, and Leela's sister. (AUDIO: The Revisionists)
When she was three years old, a year before Leela was born, Ennia was killed by a pack of Horda. Neela then killed the Horda with a knife and later gave the knife to Leela. (PROSE: Eye of Heaven)
