Gallifrey
The first televised black Time Lord appears during this Gallifrey flashback, although a black Time Lord appeared in the spin-off novel The Shadows of Avalon by Paul Cornell.
Whilst the boy Master wears a black-and-white outfit like those worn by the first Time Lords seen on screen, in The War Games in 1969, the adult Time Lords are depicted dressed in the ceremonial robes first seen in The Deadly Assassin in 1976. Created by then BBC staff designer James Acheson prior to his film career, the huge stiff collars of these outfits remained the distinctive look for officials of the Doctor's race. The collars used were the originals, on loan from the Doctor Who Exhibition in Blackpool.
The Seal of Rassilon—the equally well-established Gallifreyan symbol employed by Acheson (originally in the non-Time Lord-related Revenge of the Cybermen)—appears here for the first time since its prominent use in the television movie.
