Joy Fairn is the daughter of Harry Fairn and Miriam Wild, and Indio's twin. She was born September 4th, 1990, in the Fairn family home in Anaconda, Montana. At the age of six, Joy accompanied her mother to the Light ashram in Arizona where she has lived ever since - leaving behind her brothers Caleb, Indio, and Jesse. She settled into her new life well and became a true believer in the Light. She helped raise her younger half-sister Wynter who was born when she was seven.
In January 2013, when she is 22 and Wynter is 14, Joy escapes with her from the ashram and sends her to Caleb's house in Seattle (01 Little Sister Song). She is excommunicated as a result. Joy explains her rash action to her mother by claiming Wynter does not belong in the Light. However, Wynter believes the reason relates to a secret Joy is holding.
After one year, Joy completes her atonement and returns to the ashram (03 Rhythm and Rhyme). She leaves a farewell note for her siblings and doesn't contact them again.
