Veil (species)

The Veil were a reptilian species capable of taking over the bodies of other species.

Biology
The Veil were a reptilian humanoid race, with scaly skin and horns of various size protruding from their head and shoulders. They also had long tongues which they could flail and retract at will and would show up when they possessed someone.

The Veil were capable of possessing other beings, effectively allowing them to "jump" into their bodies. When possessed, the Veil would be able to control the person and gain some of their memories, though the original person would be able to communicate with the Veil. (TV: Prisoner of the Judoon) This possession gave off an specific type of energy. Possession by a Veil would feel very unpleasant to the possessed victim, and the victim would also be able to feel the emotions of the Veil possessing them. (TV: The Vault of Secrets)

The Veil also had the ability to stun people, a procedure which could be stopped by spraying the affected with water. (TV: Prisoner of the Judoon)

Technology
Veil ships were angular and black. They were powered by stardrives and were capable of keeping the veil in suspended animation. (TV: The Vault of Secrets)

History
The Veil were an ancient species, conquering worlds long before Earth had formed. At some point before the 21st century, the Veil home planet was turned into a ball of ice when their star was extinguished, wiping out all but Androvax, who had been travelling the stars and returned to find his people dead. (TV: Prisoner of the Judoon)

Before they had died, a ship of 100 cryogenically frozen Veil were sent out into space, but crashed on Earth in the 1970s. It was taken and stored in a vault by the Alliance of Shades. Androvax managed to free the craft from the vault and set out to find a new world for the Veil to colonise. (TV: The Vault of Secrets)
