Lud (A Handful of Dust)
From Tardis Wiki, the free Doctor Who reference
Lud was a creature that lived on the supposedly dead planet of Nemeqit. He wanted to find out what the old religion of the planet was. He said he loved questions. He wanted to help Bernice Summerfield feel as comfortable as she wanted. He turned out to be the son of Nemeqit. (AUDIO: A Handful of Dust)
