Aneth
From Tardis Wiki, the free Doctor Who reference
Aneth was a planet with a monarchy. It was the home planet of the Anethans. Hymetusite could be found on Aneth. Its people were subjects of the Skonnan Empire, but were freed when the empire collapsed. Several generations later, the Skonnans returned, demanding sacrifices of people and hymetusite, both of which were given as sacrifice to the Nimon.
The Fourth Doctor said he had visited Aneth at some undisclosed point in time and considered it a pleasant place. (DW: The Horns of Nimon)
