About me
👋 Hello, I’m Leo — a professional Game Master specializing in immersive horror roleplaying. With over 24 years of experience, I focus on delivering tense, atmospheric games built around investigation, dread, and meaningful player choice. My tables are designed for players who want suspense, strong narrative cohesion, and stories that linger long after the session ends. If you’re looking for carefully paced horror, deep immersion, and a GM who treats the game seriously while keeping it fun and welcoming — you’re in the right place. 🕯️ My Specialization: Horror & Investigative Play Horror is my main focus and strongest discipline. I specialize in games where atmosphere, mystery, and tension drive the experience: 🕵️ Call of Cthulhu – My signature system. From classic 1920s investigations to modern cosmic horror, I emphasize slow-burn dread, strong clues, and player-driven discovery. 🕶️ Delta Green – Psychological and conspiracy horror, where paranoia, secrecy, and moral pressure are as dangerous as the Mythos itself. 👽 ALIEN RPG – Cinematic survival horror in space: lethal, intense, and tightly paced, inspired by the tone of the films. My games prioritize investigation, character perspective, and narrative tension over mechanical complexity or power gaming. 🌍 About Me I’m bilingual — fluent in Spanish (native) and English — originally from Venezuela and currently based in Chile. I’ve run games for players across the USA, UK, and Spain, and I adapt my style to match each group’s experience level and expectations. I’m also a published writer, with three Call of Cthulhu scenarios released on Chaosium’s Miskatonic Repository, where my work has been praised for atmosphere, pacing, and table usability. 💡 What You Can Expect at My Table 🌑 Beginner-Friendly Horror – New players are welcome; I enjoy teaching systems and easing people into horror roleplaying. 🎭 Immersive Presentation – Atmospheric narration, music, and visual support when appropriate. 🧩 Player-Driven Investigation – Your choices matter; clever thinking is rewarded. ⏱️ Professional Reliability – Clear communication, preparation, and respect for everyone’s time. 🔥 Why Choose Me? 🕯️ Horror Specialist – Decades of experience running investigative and atmospheric horror. 📚 Published & Proven – Officially released Call of Cthulhu scenarios with real table use. 🎲 Narrative-First GMing – Focus on tension, mood, and meaningful decisions. 🤝 Respectful & Inclusive – A safe, collaborative table where everyone gets a voice. Ready to uncover dark secrets, face cosmic terror, or struggle to survive against impossible odds? Browse my available games or send me a message — I’d be glad to bring your next horror story to life. Let’s make something unforgettable together.

How Leopoldo "Leovor" Rueda creates a safe table
IMPORTANT: While it is not required to have experience in this kind of game, I do not recommend this campaign as you first Call of Cthulhu Experience, since it is a long campaign and not every element of the game may show up in the first session. If you aren't sure Call of Cthulhu is a game for you I encourage you to sign up for an one shot introductory adventure with me or other GM. These adventures are better designed to showcase the different elements of the game in one sitting. Also Masks of Nyarlathotep is a huge campaign packed with content and very rewarding payoffs, but it is a big time commitment as it contains months worth of gaming. Only sign up if you are prepared to make such a commitment. Why Join? 🎲 Immersive Roleplaying: Interact with dozens of NPCs. Your choices in dealing with them will shape your journey. 📜 Intriguing Clues: Discover and piece together clues, all meticulously recorded in the VTT as graphic and text handouts for easy reference. But don’t forget to take your own notes—what seems trivial now might be crucial later! 🗺️ Dynamic Campaign: While the opening chapters are set, the story will evolve into a sandbox-style campaign, allowing you to decide where to go next. This might feel overwhelming for beginners, but I'm here to guide you through the rules without slowing down the fun. While racism is not a main theme, historical injustices of the era and setting are acknowledged for authenticity. These elements are not highlighted or directly experienced by player characters, ensuring the story remains respectful and immersive. We begin with a thorough Session Zero to set expectations, create characters, and address any concerns. 📞 I can be reached outside of game hours via discord DM if any player need to talk about the game, has ideas, suggestions etc. also a discord text channel will be available at all times exclusively for players of this campaign Join Us for an Unforgettable Story! Ready to dive into an epic adventure? Whether you’re a seasoned player or a complete newbie, we’re here to create an unforgettable story together. Let’s make this journey one for the ages!
