Skywalker

The starship which first brought human refugees, among them Jetta, to Trycanta. Capable of holding fifty thousand passengers (and perhaps not full to capacity), only thirty-five thousand remained after an only vaguely described disaster.

The Skywalker 's original destination was Aurora, a safe, explored and uninhabited planet in the Tau Ceti system. But there was a takeover of the ship, in which many passengers, most of the crew and a number of the senior officers were killed. The attackers seemed to have been killed as well, by rebelling passengers, and in the meantime contact with Earth was lost, the ship's course altered.

Ruan Shi-wen, also known as Naomi Ruan, was the most senior surviving officer and became Captain in the aftermath. She signed Jetta on board due to Jetta's (half-forgotten) astronomical expertise, as many of their experts had died in the attack.

Another member of the crew was Victor. He had a good relationship with Jetta generally, though she could also find him annoying at times.

Eventually, after passing several stars, Jetta finds Skywalker is on course for a G-type main-sequence star, slightly larger than Sol, with an inhabitable planet - which will become known to them as Trycanta.
