Caleb Henry Fairn is the eldest son of Harry Fairn and Miriam Wild, born January 12th, 1988 in the Fairn family home in Anaconda, Montana. Along with his three younger siblings Indio, Joy, and Jesse, he was raised by his single mother until the age of nine. He and his brothers were then raised by their father, moving to Seattle when he was 15. Due to Harry's inadequacies, Caleb took over the role of father figure to his brothers from a young age.
Caleb joined the US Coast Guard after high school, eventually achieving the rank of Petty Officer First Class. He receives a medical discharge at age 26 and works as a military contractor.
Upon the arrival of his half-sister Wynter in January 2013, Caleb attempts to get custody of her. The family moves from Columbia City, Seattle, to an old farmhouse on Tiger Mountain, which he's slowly renovating.
Caleb plays bass in Rule212 and sings back-up vocals, as well as being the band manager. He took free piano lessons at school in Montana from third to eighth grade. He started playing guitar as a young teenager, then switched to bass when he was 15 so he and his brothers could form a band, the Fairn Boys.
