About the adventure
💡 Edge of Darkness — A Call of Cthulhu One-Shot A former acquaintance reaches out with a desperate plea—one last request before death. Years ago, something went terribly wrong. Now, the consequences have come due. You are entrusted with a task that was never completed… and should never have been left unfinished. What begins as a favor becomes a race against time as you uncover the truth—and prepare to confront it. 🎭 Why My Table? I’ve been running tabletop RPGs for over 20 years, with a strong focus on Call of Cthulhu. I specialize in guiding players through tense, immersive investigations while keeping the game clear, engaging, and easy to follow. At my table, you can expect: 🕯️ Atmospheric tension that builds naturally 🔍 Clear objectives and meaningful choices ⚡ Focused pacing with a strong, memorable finale 🎙️ Immersive narration and sound design 🧭 This Game Is Perfect If You: ✔ Want a complete Call of Cthulhu experience in one session ✔ Enjoy mysteries that lead to decisive action ✔ Like tension that builds toward a final confrontation ⚠️ Table Expectations This is a roleplay-driven horror experience. Players are expected to: • Engage with the investigation and the situation • Respect tone and immersion during key moments • Work together when it matters Light humor is welcome—but not at the expense of the experience. ⚠️ Some Things Should Not Be Left Unfinished The past has caught up. The ritual must be completed. Whatever happens… happens tonight.

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
I run structured, respectful horror games where expectations are clear from the start. All scenarios include content notes, so players can make an informed decision before joining. I don’t alter the core content of a scenario, but I’m always open to straightforward communication. If something becomes uncomfortable, you can speak up, step away, or we can briefly redirect the scene. My table is built on common sense, mutual respect, and clear communication. The goal is to create tension and immersion while maintaining a comfortable and controlled environment for everyone at the table.
