Norna

Norna was a member of the human colony on Frontios, and the daughter of Range.

Biography
Norna was born on Frontios and she assisted her father in his science-related workings. When the Fifth Doctor came to Frontios, Norna helped him aid the sick.

Norna told Tegan and Turlough that an acid jar could be used to power the phosphor lamps so that they were brighter. She bargained with Plantagenet to be allowed entrance to the research room on the colony ship. Once she gained entrance, she helped Tegan and Turlough sneak in. Together they managed to lever an acid battery out of the ship and carried it back to the Doctor.

Norna and Turlough returned to the research room and explored the caverns beneath it. Norna was captured by Tractators, as was the Doctor. They were freed when Tegan threw a phosphor lamp among the Tractors as the explosion injured them.

Turlough was sent into shock due to an ancestral memory of the Tractators and Norna was left to care for him. She eventually returned to the surface and was captured by Cockerill and his fellow deserters. She managed to cut herself free from her bonds and told the deserters than Plantagenet had not been killed. They followed her into the caverns to see for themselves.

After the Tractators were defeated, Norna and the other colonists bade their farewells to the Doctor and his companions. The Doctor told them not to speak of his visit to the colony as is went against the Time Lord non-interference policy. (DW: Frontios)
