Synopsis by Hal Erickson
Sucked into a black hole in space, the Liberator crew comes across a hitherto uncharted domain. The area is held in thrall by the Thaarn (Marcus Powell), a creature from the mythology of Cally's home planet. Recognizing someone from his own culture, the hideous Thaarn demands that Cally (Jan Chappell) marry him. Meanwhile, Avon (Paul Darrow) and Tarrant (Steven Pacey) are faced with their own particular horror -- this one of a mathematical variety. "Dawn of the Gods" was originally broadcast on January 28, 1980.
