About the adventure
Cthulhu sleeps in the corpse city of R’lyeh, watching centuries pass in silence. Now the stars are realigning, and his worshippers believe the time has come for their god to rise. In 1920s Boston, the Hermetic Order of the Silver Twilight, an exclusive society of scholars, politicians, and social elites, hides a far darker purpose behind its respectable façade. Shadows of Yog Sothoth is a globe spanning Call of Cthulhu campaign of investigation, cults, and cosmic horror, suitable for new and experienced players alike, focused on atmosphere, discovery, and the slow erosion of sanity.

Meet the Game Master
About me
I’ve been running weekly games on Fantasy Grounds for around 10 years and have hosted 500+ sessions as a virtual Gamemaster. I run a wide range of systems and modules, including Call of Cthulhu, Vampire: The Masquerade, and many of the classic and modern D&D adventures. A large portion of my library has been personally converted to Fantasy Grounds from original books or PDFs, often because I want to run something now rather than wait for an official release. Prepping and running games has been a long-standing passion of mine. It started in the late 1980s when I picked up my first Fighting Fantasy gamebook and realised tabletop roleplaying was something special. Since then, game preparation, adaptation, and presentation have become a genuine special interest. At the table, I value atmosphere, pacing, and player engagement.

Creating your character
The first session will be a free Session Zero. We’ll talk through the game’s tone and themes, set expectations, agree on table boundaries and the code of conduct, and then create characters together. Players can either create a new investigator with my guidance or choose from a selection of pre-generated characters I’ve prepared. Character creation will follow the standard Call of Cthulhu rules, with stats rolled or assigned during Session Zero so everyone starts on equal footing. All investigators begin as starting characters appropriate to the 1920s setting. No prior system experience is required, and no additional books are needed beyond what I provide. If time allows during Session Zero, we’ll begin the adventure so everyone can ease into play.
What to expect
Preparing for the session
Before the game, you’ll need the following: A desktop or laptop computer. This game is not suitable for phones or tablets. A headset with a microphone, set to push-to-talk. Laptop microphones, speakers, or playing from across the room won’t work for this game. A Discord account for voice chat. If you’re unfamiliar with Discord, I’m happy to help you get set up. Fantasy Grounds Unity installed and ready to go. You do not need to purchase a licence to play in this game. Don’t worry if you’ve never used Fantasy Grounds before. There’s a small learning curve, but I’ll guide you through the basics, and most players are comfortable after a session or two. It’s a powerful virtual tabletop and well worth learning.
What flashingturtle brings to the table
What I Provide I bring a Fantasy Grounds Ultimate licence and over 10 years’ experience running games on the platform. Players only need Fantasy Grounds Unity installed to join; no purchase or licence is required. I use a large library of maps, tokens, handouts, and images, shared directly to your screen to support immersion and investigation. My GM style prioritises atmosphere, pacing, and player choice. Combat is dangerous and meaningful rather than tactical or grindy. I occasionally use ambient audio or a soundboard to enhance key scenes. New players are very welcome. I’m experienced at teaching both Call of Cthulhu and Fantasy Grounds, and for the first few sessions I can handle rolls and interface elements so you can focus on roleplay and decision-making. I generally run rules as written, with flexibility where it improves flow and tension.

How flashingturtle creates a safe table
This campaign contains themes of cosmic horror, psychological distress, cult activity, and the gradual loss of certainty and sanity. Players may encounter violence, body horror, existential dread, and morally challenging situations. These themes are presented for atmosphere and tension, not shock value. During the free Session Zero, we’ll discuss tone, expectations, and boundaries so everyone knows what kind of experience they’re signing up for. I encourage players to speak up if something feels uncomfortable or isn’t working for them. During play, anyone can pause the game, change direction, or step away at any time. I’m happy to check in after intense scenes and make sure everyone is comfortable before continuing. The aim is to create an unsettling, immersive horror experience that remains respectful and enjoyable for everyone at the table.
