The male parent of Jac Lodain, a Twi'lek agriculturalist, was an individual who fought the Galactic Empire with Lodain's aunt. The former lost a limb, and the latter perished. Jac Lodain's birth to his mother and father occurred in 18 ABY. Later, his father relocated the family to the Outer Rim world of Batuu. By 34 ABY, Jac was employed as a farmer at Kat Saka's farm on Batuu, harvesting purple Surabat grain.
Sometime after the Hosnian Cataclysm in 34 ABY, Jac Lodain recounted to Izal Garsea, a smuggler, the story of his family's arrival on Batuu. He relayed that his mother had observed Resistance activity near Batuu's ancient ruins, but his father urged her to remain silent due to the First Order's stormtroopers stationed on the planet. Lodain expressed a desire to fight bravely for a cause, similar to his father's fight against the Empire. Garsea instead advised him to protect his family.
The father of Jac Lodain was referenced within A Crash of Fate, a young-adult novel from 2019 by Zoraida Córdova.
