Moya and her crew follow Larraq's former flight path to a secret PK Gammak base, in search of a way to save Aeryn from a near-fatal injury. Reaching their destination, Crichton and Chiana successfully infiltrate the base and obtain what they need with the help of an old friend. Crichton tries to return to Moya, but is captured by Scorpius, a hybrid Scarren-Sebacean. Crichton is trapped in Scorpius' Aurora Chair, an inquisition device where his memories are literally torn from his mind.
