Many cycles before Farscape began, Sierjna left her homeworld of Delfarion on board a Leviathan, traveling to an unknown destination. On her journey, she was spotted by the alien Mu-Quillus, who fell desperately in love with her and decided to make her his by using a siren star to kill her Leviathan and everyone on board, and then trapping her soul before it could escape into the next world. Sierjna knew none of this; all she knew was that one moment she was alive and on board her Leviathan, and the next, she was in limbo, with Mu-Quillus in hot pursuit.
