About the adventure

Welcome to The First Descent, an intense and immersive Marvel Multiverse tabletop RPG experience set in the eerie depths of the Mystery Flesh Pit, a colossal and enigmatic organism discovered beneath the Texas wilderness. As part of an elite team of scientists, government agents, corporate representatives, and locals, you’ll venture into an awe-inspiring and terrifying biological anomaly. What lies within is unlike anything Earth has ever encountered: a living ecosystem filled with bio-organic horrors, ancient secrets, and the looming threat of cosmic forces beyond human comprehension. This campaign begins in the late 20th century, during the initial discovery of the Mystery Flesh Pit, long before it became a catastrophic cautionary tale. Your mission starts with exploration and scientific discovery, but as you delve deeper into the pit’s pulsating chambers, you’ll uncover its true nature—an ancient sentience tied to the Multiverse. Players will face harrowing combat encounters, moral dilemmas, and the creeping corruption of the pit’s influence. Each choice you make will shape your character and the fate of the world above. Will you risk everything to uncover the truth, or will you fall victim to the pit’s insidious whispers? Drawing inspiration from Marvel’s rich lore and cosmic horror elements, The First Descent integrates the intrigue of Roxxon’s corporate greed, the vigilance of S.W.O.R.D., and the devastating potential of an ancient celestial entity awakening beneath your feet. Expect high-stakes decisions, unforgettable NPCs, and visceral, tension-filled moments as you navigate this unique setting. Every session blends exploration, action, and psychological suspense, offering a campaign that evolves based on your group’s choices. Whether you're a Marvel fan, a horror enthusiast, or a thrill-seeker looking for a gripping, character-driven narrative, The First Descent will keep you on the edge of your seat. This campaign is perfect for players eager to explore the darker corners of the Marvel Universe, testing their courage and ingenuity against unimaginable odds. Prepare to descend, uncover the secrets of the Mystery Flesh Pit, and face the question: Can you survive what lies beneath?

How to prepare

How to Prepare for The First Descent To make the most of this immersive campaign, here are a few tips for preparation: Familiarize Yourself with the Setting The campaign combines the Marvel Multiverse with the eerie and unsettling world of the Mystery Flesh Pit. Expect cosmic horror, corporate intrigue, and a sense of discovery. Watching videos or reading summaries of the Mystery Flesh Pit lore (if unfamiliar) can help immerse you in the setting. Character Ideas Think about who your character is: Are they a scientist intrigued by the pit’s mysteries, a Roxxon employee with corporate ambitions, or perhaps a local Texan drawn into the chaos? Decide how they might react to the horrors of the pit—are they curious, skeptical, or desperate to escape? If you’re bringing in a Marvel hero or Multiverse tie-in, consider how their powers and backstory connect to the campaign’s themes of exploration and survival. Understand the Marvel Multiverse System If you’re new to the Marvel RPG system, don’t worry! Familiarizing yourself with the basics (like archetypes, powers, and dice mechanics) will help, but I’ll guide you through everything you need to know. Access to the Marvel books on Roll20 ensures you’ll have all the resources at your fingertips. Prepare for the Tone and Themes This campaign leans heavily into cosmic horror, body horror, and psychological tension. Consider your comfort level with these themes, and use the provided safety tools (like Lines and Veils) to set boundaries. Be ready for moments of intense decision-making, teamwork, and roleplay. Session Zero Attend Session Zero to finalize your character, learn about the world, and discuss safety tools and group dynamics. This session will ensure everyone’s on the same page before the story begins. If you already have a character in mind, bring your ideas to Session Zero, and we’ll refine them together. Technical Prep Ensure you’re comfortable using Roll20 for maps, visuals, and character sheets. I’ll help with any setup or troubleshooting. Have a stable internet connection, a microphone for clear communication, and headphones to reduce background noise. By preparing with these steps, you’ll be ready to dive into the mystery, horror, and adventure of The First Descent!
