Aneth
From Tardis Wiki, the free Doctor Who reference
Aneth is a planet with a monarchy. Hymetrusite can be found on the planet. They used to be subjects of the Skonnan empire, but they were freed when the empire collasped. Several generations later, the Skonnans came back, demanding sacrifices of people and hymetrusite. (DW: The Horns of Nimon)
