Dalek transport official (Hostage!)

One Dalek transport official who was a member of the Brindigulum on Valkenine that was interrupted by a slave revolt, acted as an intermediary between the captive Daleks and the victorious rebels. Though allegedly agreeing to forward the slaves' demands to the Golden Emperor, the Dalek official managed to trick the slaves into fighting among themselves, distracting them enough for the captive Daleks to wipe out their jailers and wipe out the rebels. (PROSE: Hostage!)

Behind the scenes
The transport official is illustrated as an entirely light-gray Dalek with black sense globes, similar to the Silver Daleks featured in Death to the Daleks. The History of the Daleks states that, in the original Dalek hierarchy established by the Dalek Prime, Red-and-gray Daleks were responsible for transportation.
