About the adventure
Step into the shoes of ordinary people drawn into an extraordinary nightmare. It begins in 1921—an archaeological expedition in the Peruvian Andes. You’re there for discovery, not danger. But what you find will shatter your understanding of reality. Masks of Nyarlathotep is the legendary Call of Cthulhu campaign of investigation, conspiracy, and cosmic horror. From the windswept peaks of Peru to the crowded streets of New York, from Cairo’s blazing sands to the jungles of Kenya and the neon alleys of Shanghai—your journey will span the globe and test your courage, intellect, and sanity. You’ll chase cryptic clues, infiltrate cults, face unimaginable horrors, and uncover the truth behind a dark god’s rising influence. Every discovery brings you closer to revelation—and ruin. As your Keeper, I’ll immerse you in the roaring 1920s through vivid scenes, rich characters, and nerve-wracking mysteries. Will your investigators survive long enough to stop the coming darkness, or will they fall victim to it—body, mind, and soul? Prepare for the most acclaimed horror campaign ever written. The world’s fate—and your sanity—hang in the balance.

About me
I specialize in atmospheric, story-rich RPGs where tension builds naturally, characters matter, and the world feels vividly alive. My games are designed for players who want immersion, meaningful choices, and stories that stay with them after the session ends. I particularly love horror, mystery, and dark fantasy, and I work hard to make those experiences both intense and welcoming. That means strong scene-setting, memorable NPCs, approachable guidance through complex systems, and a table culture that takes safety and inclusiveness seriously. Whether you are a veteran player or trying a new system for the first time, I aim to make the experience seamless, engaging, and player-driven. You will have room to explore, influence events, and build the kind of moments that feel earned rather than scripted. If you are looking for a polished online game with real atmosphere and real agency, you are in the right place. 🎲 Grab Your Seat Today and Let’s Create Something Amazing Together!

Creating your character
During session 0, we create characters together. Pre generated characters are available for play, however, it is recommended that players create original characters as they need to feel comfortable with playing the characters for many sessions (hopefully). These characters need to be able to work together through the campaign, so players are encouraged to coordinate with each other so that they do not create characters that cannot work together.
Before settling on a character, create 3 concepts for a character. We will choose the one that fits the setting and Pack the best. To help you brainstorm the concepts, consider the below parameters. The concept only has to be a single sentence long! When your PC is completed, your PC will: 1. Have a clear motivation. 2. Be able to collaborate effectively with other party members. 3. Have a foil within the group: someone will complement your weaknesses or serve as a friendly rival. 4. Have a well-defined personality weakness. Use the 7 deadly sins for inspiration. 5. Have a well-defined backstory. Background Story Requirements: 1. Your story must align with the setting. 2. Your character's backstory should not exceed their current level of power. 3. Be concise, no longer than one page.

Safety
How Mikael Hellstrom creates a safe table
Players should expect a role-play focused game. Session 0 involves not just a discussion about safety at the "table" but also character generation, including backstory and relations before play starts. Players are certainly invited to create families and contact networks for their characters that the Keeper can draw upon during play. The GM will adapt the story to player needs to some extent, of course, including calibrating the era.
