Mark of the Rani


 * Not to be confused with the serial of a similar name.

The "mark of the Rani" was a name once applied by the Master to a large, red circle he once observed on the neck of a human that had been killed by the Rani. It was symptomatic of some sort of biological control the Rani enjoyed over her victims. (DW: The Mark of the Rani) It indicated that the person had been killed by strangulation. (DWN: The Mark of the Rani)  Its precise operation was never divulged by the Rani to either the Master or the Sixth Doctor.
