Hellfire Club

The Hellfire Club was a semi-secret organisation of politicians, businessmen and other powerful people for drinking and debauchery. A number of people used the organisation over the centuries as a cover for attempts to conjure demons and aliens in the guise of Lucifer.

History
The club was created to mock the prevalent religion of the time. Sir Francis Dashwood continued the tradition in the 1750s. The Eighth Doctor described their activities thusly:

"[Francis Dashwood's] so-called Club was simply a group of chums who spent weekends with him at Medmenham from time to time. No doubt they drank more than was good for them, but the nearest thing they had to a manifestation of The Devil was one of their inebriated number sticking horns on his head, and jumping out of a bush yelling 'Boo!' Certainly Sir Francis was interested in reinventing the Greek Eleusinian Mysteries, but that's a far cry from human sacrifices and pacts with anyone called Lucifer."

- The Eighth Doctor

The Club fell into disrepute in the 1760s and faded into obscurity. In the following decades it was sporadically reformed by various people making serious attempts at summoning arcane beings.

In July of 1778, Shardlow lost a game of backgammon to the Celestial Toymaker at the Hellfire Club and was forced to become his slave. (PROSE: The Nightmare Fair/AUDIO: The Nightmare Fair)

Scarlette, the proprietess of a brothel on Henrietta Street in London, claimed she was the last Madam of the Hellfire Club. She used her arcane knowledge and the Eighth Doctor's help to defend Earth from an invasion of Babewyns in 1782. (PROSE: The Adventuress of Henrietta Street)

19th century
In the early nineteenth century, Lord Aldbourne set up his own version of the Hellfire Club in Devil's End. (PROSE: The Eight Doctors)

21st century
By 2003 a new Hellfire Club had been set up in Malebolgia (the 51st state in the United States of America) to assist in electing Brigham Elisha Dashwood III as their first Governor... and to continue the drinking and debauchery of their predecessors. Dashwood summoned the demon Marchosias, but the subsequent invasion of Psionovores was prevented by the Eighth Doctor. This chapter of the Club was presumably shut down soon after.

Alternate timeline
In an alternate history where Sebastian Grayle achieved immortality, the Eighth Doctor and Charley Pollard arrived in Wycombe Caves in 1806. Grayle had set up the Hellfire Club as a psychic conduit for summoning the Nimon to Earth. The Doctor and Charley interfered with Grayle's plans and stopped the invasion, but not before the Nimon had consumed most of the current membership. (AUDIO: Seasons of Fear)
