Range

Chief Science Officer Range was a colonist on Frontios.

Range had a daughter called Norna who was born on Frontios. As a doctor, Range began gathering information on the instances of unaccountable deaths. He never made this work public, even to his superiors.

When the Fifth Doctor visited Frontios, Range helped him with the wounded. He told the Doctor of the situation on Frontios and that they were at war. Range vouched for the Doctor when the Plantagenet cast doubt on his trustworthiness.

Range accompanied the Doctor into the caverns beneath Frontios and looked after Vislor Turlough when he went into shock. After returning to the surface, Range volunteered to return below to find the Doctor.

However, Turlough followed him. Worried for his daughter's safety, Range returned to the surface. On the way he was attacked by a Tractator but it freed him when it was called back to fend off an attack on Gravis.

After the Doctor defeated the Tractators, Range and the other colonists bade their farewells to him and the Doctor told them not to tell anyone of his interference as it broke the Time Lord non-interference policy. (TV: Frontios)
