I hate to break it to you, but Cradle of Filth didn't invent that logo. If anything they stole it. It is a drawing of a talisman which a member or some members of the Order of the Dragon wore. The Order of the Dragon has been around since the crusades and the father of Vlad Tepes was a member of this very group. Vlad Tepes, if you didnt know, is believed to be the historical basis for Bram Stoker's Dracula. Actually, draculya translated in Romanian means son of the dragon, or son of the devil. Vlad Draculya's father was named Vlad Dracul, due to the fact that he was a fierce warrior in the Order of The Dragon.
Also, Cradle of Filth licks balls.
