- You may be looking for the fourth episode of An Unearthly Child or the city named Gor.
Chief Gor, (PROSE: Doctor Who and an Unearthly Child) also known as the Firemaker and the Great Firemaker, provided fire for the Tribe of Gum. He was Za's father and the leader of the tribe. The Firemaker was killed before he could pass the secret of fire to anyone else. (TV: "The Cave of Skulls")
Gor taught his son Za how to make sharp stones for spears and axes, and how to make traps for tigers and bears. He would have taught Za how to make fire too, had a beast not killed Gor while he was hunting one day. (PROSE: Doctor Who and an Unearthly Child)
