Halldon

The Halldons were a race of powerful beings.

History
The Doctor once discovered an account claiming that Halldon scientists had created the Daleks by transplanting primitive humans to the planet Ameron and artificially accelerating their evolution. (RT: We are the Daleks!)


 * This account contradicts the known origins of the Daleks and is probably apocryphal.

The Halldons fought a time war with the Eternals, which resulted in the Time Lords intervening. (Doctor Who Annual 2006)
