Ruta III
From Tardis Wiki, the free Doctor Who reference
Ruta III was an icy world, though still within a range tolerable to humans. The only known inhabitants were the Rutan Host, which evolved from aquatic lifeforms and adapted to land. (DW: Horror of Fang Rock) The Queen of the Rutans lived on the planet and without her the Rutan Host would fall apart. (NA: Shakedown)
