Flidor

Flidor was a moon of Skaro. It was a dead world but it was rich in blue-veined gold, which was used to construct the casing of the Dalek Emperor. (COMIC: Genesis of Evil)

Behind the scenes

 * According to The Dalek Dictionary, a reference source published in The Dalek Book, Yarvelling was the first Dalek to travel beyond Skaro and bring back gold from Flidor.
 * There is no actual name for the blue-veined gold. "Blue veined gold" is the most suitable name for it.
