One of the many great things about Masks of Nyarlathotep is how it has so much fan-generated content, possibly more than any other roleplaying campaign ever made. There's an entire Companion, plenty of prop downloads, and oodles of advice but how to expand on it or just plain old make it better. So I wondered if I could use the New York chapter as the foundation for a Murder Mystery Event / Conspiracy LARP.
Basically Erica Carlyle pulls together interested buyers in her brother's books *and* those involved or surrounding the mystery of Elias Jackson's death to a single great soiree to see the lunar eclipse and finally get to the bottom of Elias Jackson's claims. Naturally there's a number of investigators, cultists, witnesses, conspiracy theorists, and hardened killers to sweeten the pot.
I've managed to grab a venue that has four main rooms and a foyer - one of which stands well as a library - and there are plenty of props and handouts to bring to hand, including Cryptocurium's excellent Bloody Tongue Avatar statuette that can be brought into game. The rules will be very simple to keep it fun for all and the focus on the characters rather than the traits.
The main mystery I'm figuring out now is how to include all the various props without over complicating it and making it impossible to solve. I'm figuring that I'll have the props around, as props, but ensure that you can solve it based on what people know (through their character kits) than the handouts they bring to game or which are already there.
