Aboard Moya, she learns to think beyond the strict, militaristic confines of her Peacekeeper upbringing. Born in service aboard a Command Carrier, it is the only life she has known and thus; is very well skilled in hand-to-hand and weapons combat. She also becomes a valuable and important member of Moya's crew, and a companion and romantic interest to Crichton during the series. It is only after leaving the Peacekeepers that she can begin to find out about her parentage. She has discovered that her mother, Xhalax Sun, was a Peacekeeper pilot who - against Peacekeeper regulations - fell in love with an older officer, Talyn Lyczac. They deliberately had Aeryn, a child born of love and Xhalax sneaks into Aeryn's dormitory one night to tell her so, which is strictly against regulations. To redeem her crime, Xhalax was forced by the Peacekeepers to choose between the two, and she executed Talyn so that Aeryn could live.
