Originally from Torajii Alpha, Lessak's parents were wealthy and owned a chain of coffee houses. Her mother was preoccupied with her older brother, Stephan, and Erina felt left out. She was managing one of these shops, bored out of her mind, when Riley Vashtee of the Pentallian came in. She sat down in front of him and was seduced by the idea of seeing the stars. (PROSE: 42 Prologue) She was killed by Hal Korwin, who was at the time possessed by the sentient star Torajii. (TV: 42)
