Geathian

The Geathians were the inhabitants of the city of Geath, a city known for its hospitality before the Enamour incident. They and the residents of the unnamed planet on which they lived were apparently human, although they were currently at an Elizebethan stage in technology and culture, without any contact with aliens before the Doctor arrived, so it is more likely that they were a similar species.
