However, Aeryn's Prowler was caught up in the stream of Moya's starburst when Moya first escaped from the Peacekeepers, and Aeryn was brought on board Moya as a prisoner. Because of her time spent with Crichton and the others, she was deemed "irreversibly contaminated" by the Peacekeepers and ordered to be put to death.
She was saved by the crew of Moya and since then has learned to think beyond the strict, millitaristic confines of her Peacekeeper upbringing. She is very well skilled in hand-to-hand and weapons combat and can more than hold her own in a fight. She has also become a valuable member of Moya's crew and a companion and romantic interest to Crichton.
Aeryn was raised from birth to become a Peacekeeper, and she now has difficulty dealing with the fact she can never return to her previous life. Her experiences, however, have taught her that there is more to life than the emotionless, structured existence of the Peacekeepers.
