As Blake and the crew of the Liberator made a name for themselves, Avalon reached out for passage to a safer planet than the one she found herself on. Before the Liberator arrived, Avalon was betrayed by Terloc and captured by Travis. They enacted "Project Avalon", replacing Avalon with an android replica.
The android was discovered to be an imposter while aboard the Liberator, though they were quick to rescue the real Avalon. After escaping the Federation, the Liberator deposited Avalon on a safer planet.
Avalon is derived from Blake's 7.
