A girl, she was born in the mid-20th century before her planet's scientists attempted to synthesize a life prolongation agent. The prolongation agent mutated into a virus, killing all the adults and causing the children to have slow metabolisms allowing them to live centuries for they reached puberty and succumbed to the sickness they carried.
After the Federation developed a treatment to allow the children to live normal lives, Rhea was convinced by Jahn to help him rebel against the Federation authorities on their world attempting to take charge of the wild children. (TOS novel: The Cry of the Onlies)
