Warren Gadd was a 19th century human, born in 1851.
While a child, he created a conceptual space with his mind, containing every possible book that could ever be written.
By the 1890s he was infirm, but had made a younger avatar of himself. He targeted creative homosexual men, bringing them to his house and draining their imagination to feed his library. Hardwick and Kempston persuaded him to go after Oscar Wilde, so the temporal disruption caused by the writer's premature death would bring Claudius Dark into the open. However, Leela, Henry Gordon Jago and George Litefoot were able to stop Gadd without Dark's help. (AUDIO: Beautiful Things)
