Light (Ghost Light)

Light is an alien species who travels through the universe making a catalogue of all life. He has taken Nimrod last of the Neanderthal race as a specimen. Redvers Fenn-Cooper claimed to of seen a dazzling light while hunting in Africa, he says it had wings and other features similar to that of Light, but it is not proven that this was Light. Light has been asleep for centuries while in his spaceship and while he has been life has been evolving. Josiah Samuel Smith is lights survey run under the auspices of another alien on Light's ship, Control. Josiah changes to mimic the different life on earth and in doing so leaves behind Husks. Light's form depends on his environment and so when he awakes he is human in appearance but glows with a yellow light. Light is angry that his catalogue is ruined due to life evolving and so decides to destroy all organic matter so hat it will stop and his catalog will be complete. He kills a maid and takes apart a maid in order to see how it works. He kills Inspector Mackenzie and turns him into soup and also turns Lady Pritchard and her daughter Gwendoline to stone. When the The Doctor shows Light that he too is evolving and that all life does evolve Light realises that he is wrong and is dispersed.

In appearance Light is human in figure while on Earth he has metal shoulder plates that hold his yellow cloak in place. His hair is golden and his face white. When Light moves golden light surrounds him. The Doctor tells Ace that Light travels at the speed of thought.
