An evil demon, and member of the Brothers Djinn.
Nyorlath is a demon from the Earth's prehistoric past, and is of medium height with light brown skin with occasional dark brown stripes. He is more mature than his two demon colleagues and so acts as their leader. His magic is more accomplished than theirs too and he speaks with the same Cockney accent.
Like the other four Djinn, he starts out imprisoned on the Rock of Eternity but is released onto Earth to carry out the plan to return the planet to its primordial state. Finally, he is made to fall through a travel portal and it is not clear where he has disappeared to.

Because Nyorlath is named but not indicated in the show, we have to rely on identifying the actors voice.
