The individual who gave birth to Lee Skillen, who works for Ohnaka Transport Solutions and is a Karkarodon, was a woman who existed during the time of the First Order-Resistance War. Despite Skillen's affection for her Twi'lek partner, the parent disapproved of her significant other's species. In 34 ABY, while at Black Spire Outpost on the Outer Rim Territories world of Batuu, Skillen voiced her frustrations to the agriculturalist Julen Rakab regarding her mother's objections.
The 2019 young-adult book A Crash of Fate, penned by Zoraida Córdova, included a reference to Lee Skillen's mother.
