Disciples of the Light

The Disciples of the Light were a highly advanced civilisation who, according to the Beast, lived before this Universe was created.

Appearance
Pictograms made by the Disciples show them as a humanoid species with black bodies and white heads. How much of that is simply artistic design is unknown, although many Earth cultures drew similar stick figures with black bodies and white heads. (DW: The Satan Pit)

History
Before the creation of this Universe, the Disciples battled with the Beast, and buried it on a planet later called Krop Tor, which was probably their homeworld. Both the planet and K37 Gem 5, the black hole it orbited, served as a prison for the Beast. Their means of maintaining the orbit without obvious technology surpassed even the Tenth Doctor's understanding.


 * The Disciples may also have imprisoned the Beast's son, Abaddon, using the Cardiff rift.

After the Beast was sealed away, the Disciples of Light apparently disappeared, leaving only shards of pottery and the Galis Expedition notebook. Translations were nearly impossible, since the language seemed to have no modern descendants. (DW: The Satan Pit) The Doctor's TARDIS was also unable to translate it, and the Doctor stated that the writing must be impossibly old. (DW : The Impossible Planet)


 * It is unknown to whom specifically they were Disciples, although it is possible they worshipped the Ancient Lights which originate from the same period (SJA: Secrets of the Stars) or if they imprisoned Pwccm (but not Abaddon), they may have worshipped the Light. (TWN: The Twilight Streets)
