Medattia
From Tardis Wiki, the free Doctor Who reference
Medattia was a planet rich in vegetation and swamp-like jungles and home to two main humanoid tribes with different colour skin: the Gibbles with reddy-pink coloured skin and the blue skinned Wynals. Their tribal existence was maintained by their primitive belief system in voodoo as practiced by the priest Cronker who used it to help keep the two races separate through fear using the creation of the Gibwyn creature.
A new era of racial integration was accepted in 1875 and symbolised by the marriage of the two young lovers from rival tribes when Cronker was exposed by the Eleventh Doctor. (COMIC: The Curse of the Gibwyn)
