A Call of Cthulhu version is also available at [1shotadventures.com](1shotadventures.com).  \nIn November 1879, the Paris Opera premiered La Demoiselle aux Lanternes, an unusual opera about a heroine who is always seen carrying a magic lantern that she claims guides her, though no one else can see its light. However, no one from the performance returned to their homes afterwards. It seems that the entire audience, including several influential citizens, just vanished in the middle of the performance. The authorities are baffled, and call in experts to investigate the mysterious event.  \nAn Opera Unceasing is suitable for three-to-five \"ordinary\" 100-point characters. The end of this adventure includes six pregenerated characters so groups can get started right away, but players can also create their own scholars, detectives, antiquarians, physicians, occultists, or other suitable figures.  \nCharacters introduced for the first time in the adventure are noted in ALL-CAPS. Sections marked with a person  are opportunities for specific PCs, notably the pregenerated characters from the end of this adventure.  \nThe Backstory  \nLa Demoiselle aux Lanternes was a brand new opera that starred Corinne d’Orsay, a talented and up-and-coming ingénue. However, hours before the opera’s premiere, the critical prop from the show – the heroine's lantern – vanished.  \nDesperate for a new lantern, the opera house’s director sent his propmaster to scour Paris for a new one. One was found, an antique lantern of strange design, the \"Threnolume Lantern\". Little did anyone know, however, that this strange new lantern was a horrific artifact from eons past. It had the terrible capability to send men to the Howling Vortex, a universe where all things, if they endure long enough, become only screams and raw sound.  \nThe swap of lanterns was intentional, set up by a wealthy textile magnate, the untalented and music-obsessed Maurice  \nBeaumont. He discovered the lantern and its occult secretsand plotted to have the opera's performers swept up into the Vortex. Then, he planned to channel the Vortex with a modified phonograph, and spend hours listening again and again to this opera of the damned.  \nBeaumont, however, was too cowardly to use the lantern himself. So he hired a patsy, Armand Albret, the lazy and unemployed twin brother of the lead soprano's jealous boyfriend. During the opera’s third act, just when its complex notes triggered the lantern's light, the performers and audience vanished. Armand took the lantern from the stage and swept up the remaining crew so as to leave no witnesses.  \nThe next morning, as the city of Paris realized that nobody returned from La Demoiselle aux Lanternes' inaugural performance, the authorities began their investigation. Utterly baffled by the case, the police called in the best investigative minds from Paris to assist in the matter   \n2  \nv1.0  \nAdventure Synopsis  \nAn Opera Unceasing spans three parts. In part one, the PCs are contacted by the Inspector Morel of the Paris authorities. They have no leads in the disappearance of hundreds of people at the opera the night before. The inspector asks the expert PCs to investigate the Opera House to discover what might have happened. They will discover that opera's lantern was replaced with a bizarre one at the last minute, and that Corinne had both a jealous boyfriend, Etienne Albret and wealthy admirer, Maurice Beaumont.  \nIn part two, the PCs follow these leads across Paris. This isan open-ended investigation. They will find the origin of the lantern at a local shop, find that Etienne had a twin brother, Armand, who was involved with the disappearance, and that Maurice Beaumont was involved, paying Armand to use the lantern, and disappearing the next day.
