The parent of Everi Chalis was a woman who existed before the Galactic Empire came into prominence with the Proclamation of the New Order in 19 BBY. She made her home in a ruined paper mill located on a world with a primitive culture, sharing a soiled mattress with her child. When Chalis reached the age of six years, her parent attempted to trade her to the captain of a Trade Federation exploration ship, but Everi was deemed too young. Consequently, Chalis stayed on the planet until her departure through enrollment in the Colonial Academy. Everi later spoke of her mother to First Sergeant Hazram Namir of the Rebel Alliance in 3 ABY.
The first reference to Everi Chalis's mother appeared in the 2015 book Battlefront: Twilight Company, penned by Alexander Freed.
