Rasca Darklighter was a human woman originating from the world of Tatooine. She was the sibling of Rogue Squadron aviator Gavin Darklighter, and the offspring of Silya and Jula Darklighter.
Her spouse was formerly a member of the New Republic Defense Force who perished in combat against the Yevetha during the Black Fleet Crisis. Following this unfortunate event, her brother Gavin Darklighter and his wife Sera Darklighter urged Rasca, along with her offspring, to reside with them. What was initially a short-term arrangement evolved into a more lasting one. Rasca frequently experienced feelings of remorse, perceiving herself as an imposition on her brother; nevertheless, Gavin maintained that she and her children remain.
