Drahva
From Tardis Wiki, the free Doctor Who reference
Drahva, located in Galaxy 4, was the home world of the Drahvins. (TV: Galaxy 4) It was shaped in a torus, and had a weird tilted orbit, one half was in permanent darkness and had mountain ranges on in edges of the inner and outer ring. (AUDIO: Empress of the Drahvins)
It was one of the planets which took part in the Intergalactic Song Contest. (AUDIO: Bang-Bang-a-Boom!)
