Theo, a Theelin of the male sex, was the offspring of Hackrack Bep, who held the position of Vice President on Dalnan, and his husband, Zian. During the year 230 BBY, Nihil pirates abducted Theo from the south meadowlands of Dalna and imprisoned him within an isolated shelter situated in the Maawat Mountains. While probing Nihil operations on the planet, a Jedi squad located Theo at the cabin, subsequently bringing him back to his home located in the capital city of Saludad.
