Melkur



Melkur was a name given in Trakenite culture to corrupted creatures that were attracted to the planet Traken, the seat of the Traken Union.

Biology
Melkur, literally, "a fly trapped in honey". The peaceful atmosphere of Traken rendered them immobile and harmless. There were several Melkurs attracted to Traken, most decayed without causing any long term harm. They were rendered as stone through the imobilisation.

Impersonation
The Melkur that seduced Kassia was more virulent than previous Melkurs and was revealed, shortly after the arrival of the Doctor and Adric, to be the Master's TARDIS. The Master utilised the Melkur form to become Keeper and take control of The Source. (DW: The Keeper of Traken) Nyssa and Tegan saw an illusion of the Melkur intended to frighten them. (DW: Time-Flight)

Behind the Scenes

 * The word "Melkur" is similar to "Melkor", (later called Morgoth Baulier), a character from J.R.R. Tolkien's books The Silmarillion, and The Children of Hurin. Melkor was also a malevolent creature, capable of causing weeds to sprout in the Earth around him, much like the Melkur.
