Standing on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. In the Classic World of Darkness, this region is one of the most frequently-described in Europe.
Vampire: The MasqueradeEdit
The British Isles, including London, are described in a chapter of A World of Darkness and A World of Darkness Second Edition. The first edition introduced Prince Mithras, a methuselah who ruled London for over a millennium until he was forced into torpor by the Nazis' WWII blitz on London. Mithras' seneschal, Anne Bowesley, rules as "Queen Anne" in his absence. Bloody Hearts: Diablerie Britain features a brief, sparsely detailed sojourn to London during the hunt for a slumbering methuselah's haven. By the time of A World of Darkness Second Edition, Mithras is dead, having been diablerized by Monty Coven, and Queen Anne formally rules as the Prince of London, her rule fully consolidated and uncontested by the time of her profile in Children of the Night.
London has been touched on in several historical Vampire supplements. Giovanni Chronicles II: Blood & Fire and Giovanni Chronicles III: The Sun Has Set visit London in 1666 and 1848, respectively. The former details the events of the Great Fire of London as it occurred in the World of Darkness. London is the iconic city for the Victorian Age: Vampire setting; it serves as part of the setting of the Victorian Age Trilogy, and is fully detailed in London by Night. Dark Ages Europe touches on the vampires of Dark Ages London, and Ashen Cults details the Cult of Mithras.
The founding Chapterhouse of the Arcanum is located in London. The Men in Black of the Technocracy owe their origins to the Skeleton Keys, British intelligencers who served Queen Victoria during the Victorian Age; Victoria herself is suspected to have been the head of the Technocracy during her lifetime, and is sometimes alleged to still live on in that capacity to this day. The Skeleton Keys' founder, Lord Craven, may have some connection to the London-based Victorian-era Wyrm-cult that appears in Chronicle of the Black Labyrinth. The histories of the mages and changelings of Britain are detailed in Isle of the Mighty, a sourcebook for Changeling: The Dreaming. The London Necropolis is described in Ends of Empire and, briefly, in Wraith: The Great War Rulebook.
