About Cthulhu Britannica: London
The Cthulhu Britannica: London boxed set comprises three books: The Investigator's Guide to London, The Keeper's Guide to London and Adventures in Mythos London.
The Investigator’s Guide to London is a comprehensive guide to the capital in the 1920s. It contains, amongst other things, information on public transport, the bustling party scene, the people and a whole lot about the places investigators might go in the course of your adventures. Great for both players and Keepers alike, and packed full of maps and beautiful artwork.
Secondly is the Keeper’s Guide to London, which is strictly for the Keeper’s eyes only! This book is jammed full of ideas for running Call of Cthulhu adventures set in London, including new cults and Mythos threats, advice for capturing the unique feel of the city, a ready-made private club devoted to investigating the weird and wonderful, and a whole swathe of NPCs and plot hooks that you can use in your own games.
The final book is Adventures in Mythos London, which includes three complete, standalone adventures set in the capital city: Terror on the Thames, by Peter Wright, which has the investigators caught up in a night to remember on a boat trip down the river; Those Poor Souls Who Dwell in Light, by Call of Cthulhu 7thedition author Paul Fricker, which concerns the sins of Reverend Leigh, a vicar who has come into possession of a potent artefact; and The Non-Euclidean Gate, by Mark A. Latham, which is all about what happens when seven pages from one of John Dee’s notebooks turns up unexpectedly on the open market.
But that’s not all that will be included in the boxed set: we also have six sheets of beautifully designed handouts for you to use in your games (in the physical edition these will be die-cut - you'll have to print and cut them out for yourself in the PDF edition). Some of these are taken from the scenarios in Adventures in Mythos London, others completely new to inspire your own scenarios.
The physical boxed set also contains four poster maps, including a beautifully illustrated Macdonald Gill map of Central London - these are included at screen resolution in the PDF version.
