Welcome to Age of Twilight - a role-playing game set in the end of the Victorian era.
The game take place in the end of the 19th century. Most game material will be written for adventures in or about 1890. The game can be described as a mix of Sherlock Holmes investigations, Jack-the-Ripper murders and, in the background, Cthulhu mythos (along with suitable cults and slimy things). London will be described using a mix of the real world and fictional events and characters.
